Stainless steel 904l round bar

Om Export India, is reliable Stainless Steel 904L Round Bar manufacturer and supplier. It is available in various surface finish, end finish, dimension, shapes, length, sizes and toughness. It is use in the industries depending upon the nature of application.

Stainless Steel 904L Round Bar, is a low carbon high alloy austenitic stainless steel round bar. It is broadly used in application where corrosion properties are not adequate. By addition of copper provide corrosion resistant feature. It is superior to the chrome nickel round bars mainly in acetic, sulfuric, phosphoric and acid.

However there is limited use with hydrochloric acid. It even has high pitting resistance in chloride solutions. It has high resistance to both crevice and stress corrosion cracking.

Due to its higher alloying of nickel and molybdenum it performs better than other austenitic stainless steels.

It is non-magnetic in all environment and has excellent formability and weldability. The austenitic structure also provides excellent toughness even down to cryogenic temperatures.

Stainless Steel 904L has high chromium element which maintain a passive feature which protect it in various different corrosive environment.

It has high resistance to precipitation of ferrite and sigma phases on cooling and welding compare to other stainless steels containing molybdenum. Due to the low carbon content there is no risk of intercrystalline corrosion on cooling or welding. Its maximum service temperature is at 450°C.

DIN 1.4539 rod Applications

It is use in wide range of applications and various industries. Below are a few of them:

  • aerospace industry
  • chemical industry
  • energy industry
  • food processing industry
  • oil and gas industry
  • petrochemical industry
  • power plant industry
  • pharmaceutical industry
  • pulp & paper industry
  • refining Industry

Is ASTM B649 steel 904L bars magnetic?

904L stainless steel bar is non-magnetic in all condition which provide excellent formability and weldability.

It performs better compare to other austenitic steel due to high alloying of nickel and molybdenum. It also has excellent toughness even down to cryogenic temperature.

Does SS 904L bright bar rust?

SS 904L bright bar is different from any steel due to its extra amounts of chromium, molybdenum, nickel and copper it feature superior resistance to rust, corrosion and acid.

What is the ASTM standard for 904L?

ASTM A240 standard material is a specification for Low Carbon – Chromium Nickel Molybdenum for sheets, plates and strips useful in pressure vessels and general application.

How to weld alloy 904L T-Bar?

904L stainless steel can be welded by using typical welding process. While most suitable process are tungsten argon arc welding and manual arc welding.
