Alloy Steel Welded Tubing is made up of a carefully balanced mix of alloying elements, including chromium, molybdenum, manganese, silicon, and carbon. This combination boosts tensile strength, yield strength, hardness, and resistance to wear and oxidation. Depending on the grade, these tubes typically offer tensile strengths ranging from 415 MPa to over 620 MPa, along with good elongation for easy forming and fabrication. The alloy content guarantees outstanding performance under high-temperature and high-pressure conditions while maintaining excellent structural integrity and corrosion resistance.
