Weather-resistant board selection materials and specifications

Before purchasing weather-resistant boards, you still need to determine the actual specifications and dimensions of the boards. Moreover, different materials will have certain differences in their performance and application environment. Therefore, we still need to make it clear which material meets our needs, so that we can be confident when purchasing boards. So what are its specific materials and specifications?

Types of materials

Nowadays, the more common weather-resistant plates are made of ferritic stainless steel, which contains 12%-30% of chromium. Therefore, its corrosion resistance and weldability are good, its stability is guaranteed, and its chloride stress corrosion resistance is stronger than other stainless steels. There is also austenitic stainless steel, which contains 18% chromium and about 8% other metal elements. It has better overall performance, stronger corrosion resistance, and can be used in a variety of media. Martensitic stainless steel has high strength, but its plasticity and weldability are slightly worse.

Thickness specifications

When purchasing weather-resistant boards, you still need to consider whether other overall specifications meet the requirements. Nowadays, such materials are generally used in vehicle manufacturing, bridges, etc. . Generally, we can choose and buy according to the size of the steel plate we need. Each plate has different alloy elements, and its strength and corrosion resistance will also have certain differences. Therefore, we still need to consider the thickness and size specifications, so that subsequent use is also guaranteed.
