904L (385) U.S. ALLOY CO. - Welding Products, Wires
904L is a high alloy austeniticstainless steel used to weld base metal of similar compositionand 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,
The high chromium content helps maintain a passive film, which shields the material in several corrosive environments. 904L possesses a higher resistance to precipitation of ferrite and sigma phases on cooling and welding than other stainless steels containing molybdenum like 316L and 317L.
ER385 filler metal is used primarily for welding of ASTM B625, B673, B674, and B677 materials for the handling of sulfuric acid and many chloride containing media. ER385 filler metal also may be used to join Type 317L material where improved corrosion resistance in specific media is needed.
904L, and this material is normally welded using a filler metal of the same composition as the base metal and can even be welded without filler metal. The welding consumables for 904L are 20 25 CuL covered electrode and 20 25 CuL wire. Machining The cold work hardening rate of Alloy 904L makes it less machinable than 410 and 304 stainless steels.
904L Super Austenitic Stainless Steel-Introduction
Like ordinary stainless steel, 904L can be welded by a variety of welding methods. The most common welding method is manual arc welding or inert gas welding. The welding rod or welding wire is up to the composition of the base metal and is of higher purity, but its molybdenum content is required to be higher than that of the base metal.

Stainless Steel 904L Tubes are available in sizes ranging from 1/4 in. OD to 5″ OD in. & lengths of 20 ft. Metline is a professional stainless steel 904L tube supplier and manufacturer with more than 30 years experience. Our stainless steel 904L tubes are produced in …
Sandvik 2RK65, also known as 2RK65, is a high-alloy austenitic stainless steel of '904L' type. The grade is intended for use under severe corrosion conditions within the process industry. Sandvik 2RK65 is available in a range of product forms, such as tube and pipe, billets, blooms and ingots.
Welding. Alloy 904L can be readily welded by most standard processes. Austenitic plate materials have a homogeneous austenitic structure with an even distribution of alloying elements. Solidification after welding causes the redistribution of certain elements such as molybdenum, chromium and nickel.

We offer prime quality of Indian, Chinese & US origin electrodes. 904L electrode is standardised as per grade ER385. 904L electrodes are use to weld pipes, tubes, fittings, flanges, valves covered under ASTM A213, A269, A276, A312, A479, B649, B677 specifications.
Avesta Welding AB is part of a group that is at the forefront of stainless steel technology. Designed to aid the selection of the most appropriate consumables and methods for welding stainless steels, it is hoped that the Avesta Welding Manual reflects this position. Stainless steel welding is a complex mixture of metallurgy, chemistry,
What is 904L Stainless Steel Tubing? Certain applications demand seamless stainless steel tubing for critical functions. Often, 904L stainless steel tubing is required for petrochemical, gas or nuclear applications where high pressures and exposure to corrosive environments are the norm, or if the tube’s wall is too thick to be rolled and welded.
904L is a high-alloy austenitic stainless steel with low carbon content. 904L has good resistance to general corrosion, particularly in sulfuric and phosphoric conditions. It has been application proved over many years and was originally developed to resist corrosion in dilute sulfuric acid.
Welding. 904L can be welded using common fusion and resistance methods. A more highly alloyed filler is recommended to give the optimum corrosion properties in the weld. We recommend you contact your welding consumables supplier who should provide you full assistance and information on welding 904L stainless steel.
What is 904L Stainless Steel Welded Pipe? Stainless Steel 904L Welded Pipe 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. SS 904L ERW Pipe with it 20% Cr, 25% Ni, 4.5% Mo and 1.5% Cu is often found to manufacture or repair

The corrosion resistance property of 904L stainless steel is impaired in certain environments due to the redistribution of nickel, molybdenum and chromium caused by the solidification of material after welding, although this is less evident in 904L grade.
Grade 904L stainless steel is one of many stainless steel grades that can be purchased at Tampa Bay Steel. The “L” in 904L stands for Low Carbon, specifically, that carbon added to the alloy represents .03 percent or less. This means that 904L has very good welding properties.
