S355JR carbon steel plate sheet welding standards

The S355JR carbon steel plate sheet steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the S355JR carbon steel plate sheet internal quality of the steel.

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 S355JR carbon steel plate sheet 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.
