904L pipe is a non-stabilised Low carbon high Alloy Austenitic Stainless Steel. The addition of Copper to this grade gives it greatly improved resistance to strong reducing acids, particularly Sulphuric Acid. It is also highly resistant to Chloride attack - both pitting / crevice corrosion and stress corrosion cracking. This grade is non-magnetic in all conditions and has excellent weldability and formability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures. 904L does have very substantial contents of the high cost ingredients nickel and molybdenum. Many of the applications in which this grade has previously performed well can now be fulfilled at lower cost by Duplex Stainless Steel 2205 (S31803 or S32205), so it is used less commonly than in the past.

 

YUHONG GROUP deal with Austenitic Stainless Steel, Nickel Alloy Steel(Hastelloy , Monel, Inconel, Incoloy ) seamless and welded pipe and tube already more than 25 years, every year sell more than 80000 tons of steel pipe and tube. Our client already cover more than 45 countries, Like Italy, UK, Gernmany, USA, Canada, Chile, Colombia, Saudi Arabia, Korea, Singapore, Austrial, Poland, France , ....

Description

Material 1.4539 (alloy 904L) is an austenitic special steel with high molybdenum content as well as addition of copper and extremely low carbon content.
Our product range in 1.4539 are tubes and pipes, fittings and flanges, accessories.

 

Some of the quality tests carried out by us includes:

Corrosion Test Conducted only when specially requested by the client
Chemical Analysis Test done as per required quality standards
Destructive / Mechanical Testing Tensile | Hardness | Flattening | Flare | Flange
Reverse-bend and Re. flat tests Carried out in full compliance with relevant standards & ASTM A-450 and A-530 norms, which ensures trouble-free expansion, welding & use at customers end
Eddy Current Testing Done to detect homogeneities in subsurface by using Digital Flaw-mark Testing System
Hydrostatic Testing 100% Hydrostatic Testing carried out according to ASTM-A 450 norms for checking tube leakage, and biggest pressure we can support 20Mpa/7s .
Air Under Pressure Test To check any evidence of air leakage
Visual Inspection After passivation, every single length of tubes & pipes is subjected to thorough visual inspection by trained staff for detecting surface flaws & other imperfections


Supplementary Testing : Apart from the above mentioned tests, we also carry out on the manufactured products supplementary testing. The tests conducted under this include:

 

  • Eddy Current Testing
  • O.P Testing
  • Radiography Testing
  • Corrosion Testing
  • Micro Testing
  • Macro Testing
  • IGC Testing
  • Ultrasonic testing
  • Liquid Penetrate testing
