440B stainless steel is a high-quality martensitic stainless steel with high hardness and excellent wear resistance. It is widely used in cutting tools, measuring tools, bearings and other fields that require high strength and wear resistance. Compared with SUS440A, 440B has higher hardness; compared with SUS440C, it has better toughness. During the processing, although it heats up quickly and has greater viscosity, its grinding and cutting performance is superior to carbon steel. Suitable for applications that require high hardness and good wear resistance, such as mechanical parts such as cutting tools and bearings.

PRODUCT FEATURES
PRODUCT CHARACTERISTICS OF 440B STAINLESS STEEL PLATE
440A steel and 440B steel have higher hardness; compared with 440C steel, 440B has better toughness.
It is especially suitable for making bayonet blades in the fields of cutting tools, measuring tools, bearings, valves, etc.
440B steel has excellent wear resistance and is suitable for use in high-load and high-wear environments. It can maintain a higher working life to a certain extent.
