Q355 Hot Rolled Seamless Steel Pipe
Q355 steel pipe is a Chinese low alloy high strength structural steel pipe, which replaced Q345, the material density is 7.85 g/cm3. According to GB/T 1591 -2018, Q355 has 3 quality levels: Q355B, Q355C and Q355D.
Q355 steel pipe is a low alloy, high-strength steel that is used in welded structures supporting stress and heavy loads. The Q references the yield point, while the number 355 indicates its yield strength.
Characteristics of Q355 Steel Pipe
Q355 steel pipe is a structural steel with a yield strength of 345 MPa and tensile strength of 450 MPa. It has terrific processing performance and compressive strength, which can be used to manufacture high-pressure gas pressure vessels containing less than 500 liters. Q355 also has a protective layer of rust resistance.
Uses of Q355 Steel Pipe
Q355 steel pipe has excellent mechanical properties, great weldability, and ample corrosion resistance. It can be utilized to manufacture and produce petroleum storage tanks, high-pressure vessels, boilers, ships, power stations, and many other high-load structural parts.
