Malzeme 1.4057
Stainless steel
The grade 1.4057 is a martensitic stainless steel.
1.4057 is mainly supplied in the quenched and tempered condition.
In the quenched and tempered condition, the tensile strength at room temperature is between 800 and 950 N/mm², the yield strength is at least 600 N/mm².
The nickel content gives the material X17CrNi16-2 its toughness.
We stock 1.4057 in round and flat dimensions. If you need tubes or forgings, this is also no problem.
For your important projects you will get European top quality products from us.
