what is 904 steel Welded pipe

904l stainless steel Welded Pipe Supplier

In the ERW and EFW manufacturing process 904L Welded pipe are formed by hot or cold rolling plate and welding the seam. In order to keep the outside (O.D.) surface of a 904L SS Welded pipe smooth and uniform a cutting tool called scarfing blade is used to remove the weld flash. Stainless Steel 904L Welded pipe are used especially for pipeline constructions and for larger dimensions in the process plants; any specifications and qualities are part of our supply program. SP Metal stocks & supplies ASTM B673 UNS N08904 Welded Pipe in accordance with ASTM A673 and as rolled and welded. We work with a range of material grades that include 300/400 series of stainless steel, Duplex and other specialty alloys. We can fulfill our customer's project requirements by providing ASTM B673 904L ERW Pipe sizes of between 2" to 48" with schedules that include 5S, 10S, 40 and 80. UNS N08904 Welded Pipe is used in the Petrochemical, Oil & Gas, and Industrial applications. 

SP Metal high frequency 904L electric weld (ERW) line pipe and standard 904L electric resistance weld pipe products are smoothly finished and thin-walled. They are produced by continuously forming coiled hot rolled strip into a tube and welding the longitudinal seam using high-frequency electric resistance welding. Chemical and mechanical property requirements are as prescribed by current API 5L and applicable ASTM standards.

SP Metal is the leading Manufacturer & Supplier of 904L Stainless Steel Welded Pipe in India since 2002. We strive to provide SS 904L ERW Pipe for over 40 years with the finest quality being offered at very cost-effective prices. SP Metal also has advanced post-weld bead rolling capability and advanced post-weld cross-sectional weld and parent metal cold work facilities. Special non-destructive testing methods – including eddy current, ultrasonic and pressure testing – are used to ensure a consistent weld. Just like with seamless manufacturing, welded pipe can be drawn down by plug drawing or sinking. This method can be used to create very long lengths of 904L ERW Pipe

904L Stainless Steel Welded pipe Manufacturing

At the start of the welded pipe manufacturing process so called slabs or billets are cast in a steel mill. Dependent on the external dimensions and wall thickness there are different methods of producing welded pipes and tubes: Electric Resistance Welding (ERW), Fusion Welding (EFW) and Double Submerged Arc Welding (DSAW). In the ERW and EFW manufacturing process welded pipes are formed by hot or cold rolling plate and welding the seam. In order to keep the outside (O.D.) surface of a welded pipe smooth and uniform a cutting tool called scarfing blade is used to remove the weld flash. Scarfing from the inside (I.D.) welded flash is also possible. With a heat treating at the end of the manufacturing process the weld zone of the steel pipe can be made less visible. Due to the weld seam lower operating pressures are stated in accordance with ASME compared to seamless pipes. In general welded tubes possess tighter dimensional tolerances than seamless pipes and are less costly if produced in same quantities.

904L Stainless Steel ERW Pipe Manufacturing

A process for producing welded tubes is Electric Resistance Welding (ERW) also known as Contact Welding. The manufacturing starts by cold-forming a coiled plate of steel with eligible thickness and certain width into a cylindrical shape. As the cylindrical plates come together, an electric current using heat merges the edges together to create the final product.

904L Stainless Steel EFW Pipe Manufacturing

Processing of Electric Fusion Welding, also called Continuous Welding begins as coiled steel with appropriate thickness, width and weight is made. To form a continuous ribbon of steel several coils are welded together. Then the steel ribbon is heated to the necessary temperature and formed into an oval. In the next step the edges of the tube strip are permanently pressed together by rolls in order to receive a forged weld. In the last stage sizing rolls convert the welded tube into specific dimensions.

Advantages Of 904L Stainless Steel Welded Pipe

  • 904L Stainless Steel Welded Pipe are typically more cost effective than their seamless equivalents.
  • 904L SS Welded Pipe are usually more readily available than seamless. The longer lead time required for seamless pipes can not only make timing problematic, but it also allows more time for the price of the materials to fluctuate.
  • The wall thickness of 904L Welded Pipe is generally more consistent than that of seamless pipes.
  • The internal surface of 904L ERW Pipe can be checked before manufacturing, which isn’t possible with seamless.

Stainless Steel 904L Welded pipe Alternative Grades

Possible alternative grades to grade 904L stainless steel Welded pipe

Grade

Reasons for choosing grade 904L

316L

A lower cost alternative, but with much lower corrosion resistance.

6Mo

A higher resistance to pitting and crevice corrosion is needed.

2205

A very similar corrosion resistance, with the 2205 having higher mechanical strength, and at a lower cost to 904L. (2205 not suitable for temperatures above 300°C.)

Super duplex

Higher corrosion resistance is needed, together with a higher strength than 904L.

SUS 904L Welded Pipe Heat Resistance

Grade 904L stainless steels Welded Pipe offer good oxidation resistance. However, the structural stability of this grade collapses at high temperatures, particularly above 400°C.

904L Welded Pipe Welding

Welding of grade 904L stainless steels Welded Pipe can be performed using all conventional methods. This grade does not require pre-heat and post-weld heat treatments. Grade 904L Welded Pipe can be subjected to hot cracking in constrained weldment. Grade 904L electrodes and rods are used for welding grade 904L steel Welded Pipe according to AS 1554.6.

Stainless Steel 904L Welded Pipe Machining

The cold work hardening rate of Alloy 904L Welded Pipe makes it less machinable than 410 and 304 stainless steel Welded Pipe.

904L Welded Pipe producing through Cold forming

904L stainless steel Welded Pipe is quite ductile and forms easily. The addition of molybdenum and nitrogen implies more powerful processing equipment may be necessary when compared with the standard 304/304L grades.

SS 904L Welded Pipe Fabrication

Grade 904L stainless steel Welded Pipe are high purity steels with low sulphur content. They can be machined using any standard methods. These grades can be readily bent to a small radius under cold conditions. Although subsequent annealing is not required in most cases, it should be carried out when the fabrication is performed under severe stress corrosion cracking conditions.

AISI 904L – Austenitic Stainless Steel

AISI 904L is an austenitic stainless steel that offers a strong resistance to reducing acids aswell as a good resistance to several types of corrosion. UNS NO8904, commonly known as 904L, is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate. Stainless Steel grade AISI 904L. Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content.


 


904L Stainless Steel Welded pipe Corrosion Resistance

904L gives good resistance to both organic and inorganic acids.The addition of copper in 904L grade gives excellent corrosion resistance against nickel stainless steels, to sulphuric, phosphoric, acetic acids, hydrochloric acids, etc. It also gives a high resistance to pitting in chloride solutions, an excellent resistance to both crevice and stress corrosion cracking.The 904L is much better than austenitic stainless steels due to the higher alloying of nickel and molybdenum.The high percentage of chromium content in 904L gives and maintains a passive film which protects the material in many corrosive environments.

 


Stainless Steel 904L Welded pipe Hot Forming

Hot and heat forming should be done after uniform heating.Complete annealing should be done before any hot forming in order to retain maximum ductility and corrosion resistance property. It is very important that the whole process should be done above 1100°C.

 


904L SS Welded pipe Machining

The machining of  904L  requires proper care to achieve the expected result. The cutting speed should be slow and proper care should be taken while doing so.

 


904L Welded pipe Welding

The 904L material should be allowed to cool in between, preferably to below 150°C temperatures. To obtain good welding properties welded condition, filler material shall be used.Because of high thermal expansion, welding must be carefully planned in advance to ensure that distortion of the welded joint can be kept under control.

 


Alloy 904L Welded pipe Heat Treatment

The heat treatment should be accompanied by cooling in water or air immediately. This treatment should be applied for both solution annealing and stress relieving from the 904L material.

 


stainless steel 904l vs 316l

suitable welding consumable when dissimilar materials are to be joined. welding wire and rods are filler metals optimized, 316L base metals, use 316L filler metal. Joining of stainless high-alloy NiCrMoCu grade 904L or other. 904L is a high alloy austenitic stainless steel used to weld base metal of similar composition and with its extra low residual elements such as C, Si, S, P, and N improves the weld metal from hot cracking & fissuring. 904L with it 20% Cr, 25% Ni, 4.5% Mo and 1.5% Cu is often found to manufacture or repair processing equipment, tanks, vessels, and piping that handles acetic & sulfuric acids and other chlorides. Also used for joining 317L & 904L to 304 or 316 where added corrosion resistance is needed.

stainless steel 904l Welded pipe corrosion resistance

The corrosion resistance of grade 904L is intermediate between super austenitic grades, with 6% molybdenum content, and standard 316L austenitic grades. Grade 904L is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum. This steel grade needs to be solution treated following cold working, to achieve maximum stress corrosion cracking resistance under critical environments.


 


904l SS Welded pipe casting grade

The main reason for the change was the higher pitting resistance equivalent number (PREN) measurement of 904L, which has a value of approximately 36 PREN in comparison to that of 316L that has approximately 26 PREN.
