1.4401 Stainless Steel

All You Need to Know About Austenitic Stainless Steel X5CrNiMo17-12-2, 1.4401 According to EN 10088-1


What is 1.4401 Stainless Steel Grade

The 1.4401-grade stainless steel is austenitic stainless steel that is of high commercial importance. The stainless steel grade contains molybdenum in its chemical composition. This increases its corrosion resistance. This is particularly important when it comes to crevice corrosion in chloride environments.


The 1.4401-grade stainless steel has the following properties:

  1. Good corrosion resistance
  2. Weldable
  3. Good resistance to oxidation


Why use 1.4401 Stainless Steel

The 1.4401- stainless steel grade has good machinability. While the stainless steel grade cannot be hardened by heat treatment, it can be hardened by solution treatment. The good corrosion resistance showcased by 1.4401 stainless steel grade makes its marine grade stainless steel.


What is the chemical composition of 1.4401 stainless steel?
