Surface quality of St37-2 carbon steel material

The preparation of St37-2 carbon steel material 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 St37-2 carbon steel material centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

Stainless steel is resistant to chemical corrosion, air or water and other weak corrosion media. Stainless steel covers ordinary stainless steel and acid resistant steel. St37-2 carbon steel material, Ordinary stainless steel is generally not resistant to chemical corrosion, while acid resistant steel is generally stainless. The use of stainless steel is mainly to maintain the original appearance of the building for a long time.
