All You Need to Know About Austenitic, Corrosion Resistant Stainless Steel X2CrNiMo17-12-2, 1.4404, SUS316L

 

What is 1.4404 Stainless Steel Grade

The 1.4404-grade stainless steel is austenitic stainless steel that is of high commercial importance. The steel grade contains molybdenum in the chemical composition which improves its corrosion resistance. The 1.4404-grade stainless steel shows toughness even at cryogenic temperatures.

 

The 1.4404-grade stainless steel has the following properties:

  1. Good corrosion resistance
  2. Immune to carbide precipitation
  3. Excellent toughness

 

Why use 1.4404 Stainless Steel

The 1.4404- stainless steel grade is tough and has good corrosion resistance. It comes in two versions – the low carbon version and the high carbon version. Both of them can be used for specific purposes. The austenitic structure of the steel provides it with excellent toughness as well.
