Common corrosion types and causes of A572 Gr 42 carbon steel plate sheet

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the A572 Gr 42 carbon steel plate sheet project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of A572 Gr 42 carbon steel plate sheet customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

A medium tensile, low carbon manganese steel S355JR is readily weldable and possess good impact resistance. This material is commonly supplied in the untreated or normalized condition. Structural unalloyed steel A572 Gr 42 carbon steel plate sheet has a wide range of applications in construction, metallurgy, heavy and transport engineering, machine tool, power engineering and bridge building industries. Various profiles and metal structures, parts and elements of ground and underground equipment are made from steel S355JR.

09CuPCrNi-A steel is weather resistant steel. It is also called 09CuPCrNi-A weathering steel, or 09CuPCrNi-A anti-corrosion steel. 09CuPCrNi-A steel is equivalent to SPA-H, Corten B, etc. steels. Compared with those steels, 09CuPCrNi-A steel price is cheaper while the performance is similiar. That is mainly because the demands for 09CuPCrNi-A steel is very large in China, which is one of the largest steel prodction and export country. So the production capacity of 09CuPCrNi-A steel in very large in China. Consequently, the unit cost of 09CuPCrNi-A steel is cheaper.

If the chromium content in A572 Gr 42 carbon steel plate sheet alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.
