440A stainless steel plate is a high carbon martensitic stainless steel with excellent quenching hardening performance and high hardness. Compared with 440B and 440C stainless steel sheet, 440A has higher toughness. Its carbon content is 0.75%, and it performs well in hardness and corrosion resistance. 440A stainless steel plate has the strongest rust resistance in the 440 series and is widely used in high-demand wear-resistant and corrosion-resistant occasions.

PRODUCT FEATURES
PRODUCT CHARACTERISTICS OF 440A STAINLESS STEEL PLATE
Excellent hardness>>440A stainless steel has excellent quench hardening properties and high hardness, suitable for use in applications requiring high strength and wear resistance.
Good toughness>>Compared with 440B and 440C stainless steel sheet, 440A has better toughness and is particularly suitable for applications that require both hardness and impact resistance.
Strong corrosion resistance>>Although 440A is slightly less corrosion-resistant than 440C, it still performs well in most industrial environments.
Wide range of applications>>Widely used in manufacturing tools, bearings, valves, measuring tools, etc., especially in applications requiring high hardness and toughness.
