4Cr5MoSiV1 steel has excellent wear resistance, heat resistance, and corrosion resistance, suitable for working environments such as high-speed cutting, cold stamping molds, and hot stamping molds. It has high hardness and good cutting performance, which
1.Resistance to intergranular corrosion in the as-welded condition2.Resists atmospheric corrosion3.Resistant to sulfidation4.Good stretching5.Oxidation resistance
BTC Casingis mainly used for the first drilling, drilling soft ground to the bedrock, in order to seal this part of the formation without collapsing, it needs to use surface casing to seal.
