ASTM AISI Grade 440 stainless steel round bar rod
Stainless steel bar round bar, hexagonal bar, square bar, flat bar, solid bar.
SUS440 stainless steel commonly used models have three kinds: SUS440A, SUS440B, SUS440C, and SUS440F (easy to process type).SUS440 belongs to high-strength cutting tool steel, which is martensitic stainless steel. Due to high carbon content, it is 0.95-1.2%, and the Cr content is 16-18%. It is fully hardenable and the hardness can reach HRC58.The quenching temperature is 1010-1070 and the oil is cold.Temper 100-180 rapid cooling.High yield strength can be obtained after proper heat treatment, and the hardness can reach 58HRC, belonging to the most rigid stainless steel.
440A stainless steel has excellent quenching and hardening properties, high hardness, and higher toughness than 440B and 440C.
Used as cutting tool, measuring tool, bearing.
440B stainless steel has higher hardness and toughness than 440A steel.440B stainless steel for cutting tools, measuring tools and bearings, valves.Suitable for bayonet blade material.
440C has high hardness after quenching.It is mainly used for manufacturing bearing parts working in corrosive environment and non-lubricated strong oxidizing atmosphere.440C has good temperature properties and can also be used as corrosion-resistant high-temperature bearing steel.Good corrosion resistance (magnetic) tableware (knife), turbine blade hardened, higher hardness than 440A steel (magnetic), can be used to produce high-quality blade, pipe mouth, valve, plate ruler, tableware, knives, such as medical scalpel, scissors, nozzle, bearing, etc.
