High strength S420ML equivalent ASTM good performance

SA387 GR22 CL2 steel plate has the properties of preventing hydrogen embrittlement, hydrogen corrosion, hydrogen peeling, and sulfide corrosion, as well as good low temper embrittlement. It is widely used in the manufacture of fertilizer, petrochemical and thermal power plant equipment. BBNSTEEL has leading production technology, and there are many S420ML equivalent ASTM products in stock. If you need to fix it, it can be 8mm-120mm-650mm thick and wide to 3900mm.

The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, S420ML equivalent ASTM flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.

The preparation of S420ML equivalent ASTM galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for S420ML equivalent ASTM centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
