APPLICATION: 
This material is mainly used for the production of special construction parts, valves, bearings, parts of fittings subject to abrasion, tools, guide rollers, bushings, rings, kitchen knives, ball bearings, hunting knives and knives used in food processing , which additionally require basic resistance to simple corrosive environments. 
SPECIFICATION: 
High-chromium and at the same time high-carbon stainless steel with a martensitic structure, made of which ready components are subjected to hardening and tempering. It is characterized by high hardness >55 HRC, while maintaining good resistance to corrosive environments and resistance to operating temperatures <400 ºC.Together with high hardness, the material is highly resistant to abrasion and wear, so the grade can be classified as a corrosion resistant bearing or tool steel.

Product Description

 
The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-free. Stainless steel plates refer to steel plates that are resistant to corrosion by weak media such as air, steam, and water, while acid-resistant steel plates refer to steel plates that are resistant to corrosion by chemically aggressive media such as acids, alkalis, and salts.
