Product introduction

Product characteristics

440C stainless steel flat steel has the highest hardness of all stainless and heat resistant steels. It is used for nozzles, bearings, automatic lathes, etc. Martensitic stainless steels have the same hardening properties as ordinary alloy steels through quenching, so a wide range of different mechanical properties can be obtained by selecting the grade and heat treatment conditions.

440C stainless steel flat steel has high hardness and is mainly used to manufacture bearing parts that work in corrosive environments and non-lubricated strong oxidizing atmospheres. 440C has good resistance to high temperatures, so it can also be used as corrosion-resistant high-temperature bearing steel. In addition, it can also be used to manufacture high quality tools such as medical scalpels, scissors, nozzles, bearings, etc.

440C steel is a martensitic stainless steel. It contains 1.0% carbon and 16-18% chromium. It is a high quality stainless steel with strong rust resistance.

Scope of application: It is mainly used for manufacturing bearing parts that work in corrosive environments and non-lubricated strong oxidizing atmospheres. 440C has good high temperature dimensional stability, so it can also be used as corrosion resistant high temperature bearing steel. In addition, it can also be used to manufacture high-quality tools, such as medical scalpels, scissors, nozzles, bearings, etc. 440C has a low ability to withstand dynamic loads.

Scope of Application:

Mainly used for manufacturing bearing parts working in corrosive environment and strong oxidizing atmosphere without lubrication. 440C has good high temperature dimensional stability, so it can also be used as corrosion resistant high temperature bearing steel. In addition, it can also be used to manufacture high quality tools such as medical scalpels, scissors, nozzles, bearings, etc. 440F: is a steel grade to improve the easy cutting properties of 440C steel for automatic lathes, ordinary alloy steel like hardening characteristics through quenching, so a wide range of different mechanical properties can be obtained by selecting the grade and heat treatment conditions. 440C has a low capacity to withstand dynamic loads

Characteristic:

440: High strength cutting tool steel, slightly higher carbon content, after appropriate heat treatment can be obtained after high yield strength, hardness can reach 58HRC, belong to the hardest stainless steel among. The most common application example is "razor blade". There are three common types: 440A, 440B, 440C, and 440F (easy to machine).
