T4003 stainless steel is an economical grade with low chromium and low nickel content, offering good corrosion resistance. It fills the material gap between stainless steel and coated steel for applications requiring a certain level of corrosion resistance. With excellent weldability and formability, it is mainly used in railway freight car bodies, street sweepers, flue ducts, railings, and similar applications.

系列产品简介

410

410 stainless steel offers high strength, good toughness, excellent corrosion resistance, and favorable machinability. It is mainly used for components that require relatively high toughness, a certain degree of corrosion resistance, and the ability to withstand impact loads.

420J1

20Cr13 stainless steel exhibits high hardness in the quenched state and good corrosion resistance. It is mainly used for making cutting tools, qualifying as a “cutlery grade” martensitic steel. It is also employed in surgical knives and, additionally, in applications such as steam turbine blades, offering a wide range of uses.
