410 STAINLESS STEEL BAR
410 STAINLESS STEEL BAR
410 is the basic, general purpose, hardenable martensitic stainless steel. It is used for highly stressed parts with good corrosion resistance and strength.
APPLICATIONS:
- Cutlery and kitchen utensils
- Steam and gas turbine blades
- Fasteners
- Valve components

Martensitic:
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.
