What is weather-resistant steel?


What is weather-resistant steel?

Weathering plate that is resistant to atmospheric corrosion steel, is a low alloy steel series between ordinary steel and stainless steel, weathering steel from ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements, with high-quality steel, strong, plastic extension, forming, welding, abrasion, high temperature, fatigue resistance and other characteristics.Today's fast horse steel to share with you!

The use of weathering plate.

1. High performance weathering steel and fire-resistant steel can reduce the maintenance costs of steel structures, providing a new solution to the problem of fire and corrosion of exposed unprotected steel structures, such as high-voltage towers.
2.The production and installation process of fire-resistant weathering steel is basically the same as conventional steel, and the design method is the same as ordinary steel structures, but more tests are needed to verify.
3.High strength weathering steel has been used in bridge projects, need to study the design theory and method.
4.Fire-resistant weathering steel can also be used in floor bearing plate.

Weather resistant steel quality

1、Ferrite stainless steel. Contains 12% to 30% chromium. Its corrosion resistance, toughness and weldability with the increase in chromium content and improve the chloride stress corrosion resistance than other types of stainless steel.
2, austenitic stainless steel. Contains more than 18% chromium, but also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Comprehensive performance is good, can be resistant to a variety of media corrosion.
3, austenitic. Ferritic duplex stainless steel. Combines the advantages of austenitic and ferritic stainless steel, and has superplasticity.
4, martensitic stainless steel. High strength, but plasticity and weldability is poor.

The above is the sharing of fast horses, I hope it can help you
