MS Seamless Carbon Steel Pipes Black Painted Erw Welded Carbon Steel Round Tube
Q345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel, material density is 7.85 g/cm3, tensile strength is 470-630 Mpa, and yield strength is 345 MPa, it has better properties than Q235. According to GB/T 1591 – 2008, Q345 material has 5 quality grades: Q345A, Q345B, Q345C, Q345D and Q345E.
Q345 steel has good weldability, cold & hot workability and corrosion resistance. Widely used in bridges, ships, boilers, pressure vessels, petroleum storage tanks, lifting transport machinery and other high-load welded structural parts.
Meaning & Designation
“Q” is the first letter of Chinese Pinyin: “qu fu dian”, that means Yield Point, “345” is the minimum value of yield strength 345 MPa for steel thickness ≤16mm.
