What are the welding precautions for EN steel grade S420N material

Our company was founded in 2000, which initially committed to providing high-quality steel EN steel grade S420N material products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export EN steel grade S420N material steel to the international market, opening up the international steel market.

Alloy plate is a kind of steel plate with high thermal strength and oxidation resistance at high temperature, which has certain hydrogen corrosion resistance. Alloy plate is a new type of steel plate formed by adding other elements on the basis of steel plate material, which is to solve the problems existing in ordinary carbon steel plate. Alloy plate can be divided into bridge steel plate, boiler steel plate, shipbuilding steel plate, armored steel plate, automobile steel plate, roof steel plate, structural steel plate, silicon steel sheet, spring steel plate, EN steel grade S420N material, etc.

We have 4 typical production lines EN steel grade S420N material, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.

EN steel grade S420N material, Hot rolled seamless tube is usually produced on automatic tube rolling mill. After the solid tube blank is inspected and the surface defects are removed, it is cut to the required length, centered on the end face of the piercing end of the tube blank, then sent to the heating furnace for heating, and perforated on the piercing machine.
