Rashdan Pipes and Tubes, a leading manufacturer and supplier in Amman, Jordan, excels in producing Stainless Steel 321/321H Seamless Tubing, titanium-stabilized austenitic grades for high-temperature stability and corrosion resistance. Compliant with ASTM A312 TP321/TP321H and A213 standards, these seamless tubes offer superior resistance to intergranular attack during welding, ideal for petrochemical, aerospace, and power applications up to 1500°F. From its Jordanian base, Rashdan provides precise seamless fabrication, rigorous testing, custom sizing, and global delivery for demanding thermal and corrosive environments.
Stainless Steel 321/321H Seamless Tubing features 17-19% chromium, 9-12% nickel, carbon 0.08% max for 321 and 0.04-0.10% for 321H, max 2% manganese, max 0.75% silicon, max 0.045% phosphorus, max 0.03% sulfur, and titanium 5x(C+N) min to 0.70% max, with density 7.9-8.0 g/cm³. The stabilization prevents carbide precipitation, ensuring oxidation resistance up to 900-1500°F and good aqueous corrosion performance. Mechanical properties include tensile strength min 515 MPa, yield strength 205 MPa, elongation 40% min, and hardness max 217 HB.
