Stainless Steel Grade 440c Properties

Astm a276 standard grade 440c stainless steel is a high carbon martensitic stainless steel.

Stainless steel grade 440c properties. Grade 440c stainless steel is a high carbon martensitic stainless steel. Grade 440c stainless steel is a high carbon martensitic stainless steel. It has better temperature resistance than 304 stainless steel. Ss 440 stainless steel ss 440a 440b and 440c stainless steel are aisi and astm standard high carbon high chromium martensitic stainless steel ss440 has high strength good hardness corrosion resistance wear resistance and high temperature dimensional stability.

It has high strength moderate corrosion resistance and good hardness and wear resistance. It has high strength moderate corrosion resistance and good hardness and wear resistance. The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity k or λ measured in w m k. It has good resistance to the atmosphere fresh water and mild acids.

Grade 440c stainless steels are high carbon steels which attain the highest hardness wear resistance and strength of all stainless steel grades after heat treatment. Type 440c is a martensitic stainless steel with high carbon and chromium content. These properties make this grade suitable for applications such as valve components and ball bearings. The thermal conductivity of martensitic stainless steel grade 440c is 24 w m k.

It belongs to the general model which is 18 8 stainless steel. The 303 stainless steel can be machined more easily than 304 stainless steel by adding a small amount of sulfur and phosphorus. Gb grade is 0cr18ni9. Otai steel supplies reliable quality of 440c steel materials.

Its very high carbon content of 1 0 is responsible for these characteristics which make 440c particularly suited to such applications as ball bearings and valve parts. The following datasheet gives an overview of grade 440c stainless steel. It is a measure of a substance s ability to transfer heat through a material by conduction. Grade 440c is capable of attaining after heat treatment the highest strength hardness and wear resistance of all the stainless alloys.

Compared to austenitic grades 440c has moderate corrosion resistance comparable to 304.
