Galvanized sheet refers to the steel plate with a layer of zinc on its surface. Galvanizing is an economic and effective anticorrosion method of steel plate. Galvanized sheet can be divided into hot galvanized sheet and electro galvanized sheet according to production process. The zinc layer of hot-dip galvanized sheet is thick, which is used for S690QL1 for sale parts with strong corrosion resistance. The thickness of zinc layer of galvanized sheet is thin and even, which is mostly used for painting or indoor products.

15CrMo alloy steel plate is pearlite structure heat-resistant steel, which has high heat strength (δb≥440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of steel S690QL1 for sale is obvious and the weldability is poor. 15crmo alloy steel plate is mainly used in petroleum, petrochemical, high-pressure boilers, etc.

Heat treatment is a very important process to improve the performance of S690QL1 for sale etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.
