Description

Introduce

405 stainless steel:

As a composite steel, 405 stainless steel does not harden significantly when cooled from high temperatures.


409 stainless steel:

Ferritic stainless steel 409 is commonly used in machinery, construction, and other engineering applications. Due to the presence of austenite grains, its mechanical properties are greatly improved. Furthermore, due to the addition of a lot of alloying elements, the strength and hardness are also greatly increased.


430 stainless steel:

430 stainless steel is a corrosion-resistant, general-purpose steel. It has a better thermal conductivity than austenite, a lower thermal expansion coefficient than austenite, is resistant to thermal fatigue, and is stabilized by titanium, so the weld has good mechanical properties. Architectural decoration, fuel burners, household appliances, and home appliance parts are among the applications of 430 stainless steel.


434 stainless steel:

The corrosion resistance, toughness, and weldability of 434 stainless steel increase as the chromium content increases, and it is more resistant to chloride stress corrosion than other types of stainless steel.


444 stainless steel:

It contains 18% chromium and 2% molybdenum, and is a ferritic stainless steel with low carbon and nitrogen content. This steel grade is ideal for various water treatment devices.


403 stainless steel:

In accordance with the American ASTM standard, 403 stainless steel pipe is a good heat-resistant stainless steel for high stress applications.


410 stainless steel:

410 stainless steel: good corrosion resistance, machinability, general purpose blades, valves


420 stainless steel:

420 stainless steel is a martensitic stainless steel, with certain wear resistance, corrosion resistance, high hardness, and other characteristics, making it a good choice for a wide range of precision machinery, bearings, electrical appliances, equipment, instruments, meters, transportation tools, household appliances, etc. Parts resistant to atmosphere, water vapor, water, and oxidative acid corrosion are mostly made from it.


440A stainless steel:

This stainless steel has excellent quenching hardening properties, high hardness, and a higher toughness than 440B steel and 440C steel.
