Case hardening steels | The Engineer The Engineer
A new hardening process called Kolsterizing offers some tangible benefits over earlier techniques Austenitic stainless steels, like 316 and 304, are known to offer the benefits of corrosion resistance. However, disadvantages include a limited wear resistance and increased risk of galling. Galling, or fretting, occurs when two contacting surfaces, normally at rest, undergo minute oscillatory [.]

The Basics of Stainless Steel Temper Conditions | Ulbrich
For example, increasing the Nickel content in austenitic stainless steel will slow down the work hardening rate. This is why 301 stainless steel (6-8% Nickel) work hardens faster than 304 stainless steel (8-10% Nickel). This increase work hardening rate means that you can achieve higher strengths without losing as much ductility.
