Grade 1.8931 equivalent equivalent astm material

Our company was founded in 2000, which initially committed to providing high-quality steel 1.8931 equivalent 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 1.8931 equivalent steel to the international market, opening up the international steel market.

Good weldabilityBecause of its low carbon content, low alloy element content, good plasticity and low hardenability, this material 1.8931 equivalent is not suitable to have quenching structure or crack at the weld. The cold and hot pressure processing performance is good. Because of its good plasticity and small deformation resistance, it is not easy to produce cracks after pressure processing. Good corrosion resistanceUnder various atmospheric conditions, it has higher corrosion resistance than carbon steel.

During the construction of hot-dip 1.8931 equivalent galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the 1.8931 equivalent construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.
