Product Description

Hot Sale AISI 440c X105crmo17 1.4125 SUS440c 1.4057 SUS431 Round Stainless Steel 

1: 440C Stainless steel introduction

ASTM A276 standard grade 440c stainless steel is a high carbon martensitic stainless steel, which is generally supplied in the annealed condition with a maximum Brinell hardness of 269 (Rc29) or annealed and cold drawn with a maximum Brinell hardness of 285 (Rc31).

AISI 440C steel is characterized by good corrosion resistance in mild domestic and industrial environments, including fresh water, organic materials, mild acids, various petroleum products, coupled with extreme high strength, hardness and wear resistance when in the hardened and tempered condition. Grade 440C stainless steel is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Small AISI 440C steel sections can be air cooled and quite large sections oil quenched for maximum through hardness.
