Super Duplex 1mm Stainless Steel Sheet Mirror Finished 440c 409L

1. Introduction

440C steel is a Martensite type of stainless steel. Carbon content 1.0%, chromium content 16-18%. Strong rust resistance, high quality stainless steel.

Scope of application: Mainly used for manufacturing bearing parts in corrosive environment and strong oxidation atmosphere without lubrication. 440C has good dimensional stability at high temperature, so it can also be used as corrosion resistant high temperature bearing steel. In addition, it can also be used to manufacture high-quality cutting tools, such as medical scalpels, scissors, nozzles, bearings and so on. The 440C has a low capacity to withstand dynamic loads.
