If stainless steel having austenitic structure at high temperatures and having a Cr content of 0.1% by weight is watered, the austenitic structure transforms into a martensitic structure. The martensitic structure is a structure with high strength and hardness; The fragility is also relatively higher. Since the excess hardness will also cause fragility, the hardness can be lowered a little and the strength can be brought to the desired level by tempering during the manufacturing process.

They have moderate corrosion resistance, heat treatability, magnetism and low welding abilities.

Some Applications: Knives, surgical instruments ...
