Austenitic Stainless Steels

At its most basic, H1 is an austenitic stainless steel. Austenitic stainless steels are about as old as stainless steel itself, being developed by German metallurgists in the approximate time period of 1909-1912. They worked on 18% Cr, 8% Ni steels which are quite similar to common austenitic stainless steels like 301, 302, and 304. read more

Annealing

How Annealing of Steel Works – Subcritical vs Transformation Annealing

Why Anneal?

There are three primary goals of annealing steel:

  1. Make the steel machinable so that it can be easily cut, drilled, and ground.
  2. Setup the steel for austenitizing and quenching (hardening) so that is has good heat treating response
  3. Provide the best possible properties in the final heat treated product

The above goals are not always 100% compatible, but we would like to offer the optimal combination based on our priorities. However, to know what the trade-offs are we need to know how annealing works first. read more
