DIN En Standard E235 E355 Cold Drawn Seamless Weld Precision Steel Tube
Characteristics and scope of application of precision seamless steel pipe: It is a weldable low alloy high strength steel with yield strength of 686MPa grade, and has good comprehensive mechanical properties. After different heat treatment, different comprehensive mechanical properties can be obtained to be suitable for different working conditions. Its corrosion resistance is higher than that of mild steel (about three times). Suitable for manufacturing all kinds of pressure vessels and engineering mining machinery and truck and other parts.
