Nitrided Steel Sheets

Case hardening is a simple process of hardening the surface of a metal object.

Nitrided steel sheets.

Nitriding steel is steel treated by a highly specialized surface hardening process known as nitriding which is a heat treating process that diffuses nitrogen into the surface of a metal to create a case hardened surface. 0 to 0 1 v. Stainless steels ferritic martensitic austenitic ph grades cast iron grey or nodular. Less than or equal to 0 10 mn.

The processing associated with nitriding does have some advantages in avoiding problems such as quench cracking and distortion. Also known as flat stock the thickness on these sheets and bars is held to a tight tolerance. Hardened multipurpose 4140 alloy steel bars. These processes are most commonly used on high carbon low alloy steels.
