Product Description

416 Stainless Steel Bar

416 Stainless Steel Bar

416 stainless steel bar is a free-machining variation of martensitic stainless steel with the addition of sulphur or selenium. The material can be hardened by heat treatment to higher strength and hardness levels. It has better machining properties than the austenitic grades, but lower corrosion resistance.


Applications of 416 Stainless Steel Bar:

•Cutlery and kitchen utensils
•Steam and gas turbine blades

The characteristic orthorhombic martensite microstructure was first observed by German microscopist Adolf Martens around 1890. Martensitic steels are low carbon steels built around the Type 410 composition of iron, 12% chromium, and 0.12% carbon. They may be tempered and hardened. Martensite gives steel great hardness, but it also reduces its toughness and makes it brittle, so few steels are fully hardened.
