ASTM A312 TP316Ti Stainless Steel Thick Wall Seamless Pipe
Leave a message
ASTM A312 TP316Ti stainless steel thick wall seamless pipe is a high-performance titanium-stabilized austenitic stainless steel pipe specifically designed for applications with extremely high requirements for corrosion resistance, high-temperature stability, and thick-wall structural integrity.
GNEE supplies high-quality ASTM A312 TP316Ti pipes, manufactured using precision rolling or extrusion processes. The thick-wall variant (typically with wall thickness ≥3.0mm) is produced through controlled hot working and solution annealing (1040-1100°C, followed by rapid cooling) to achieve a uniform microstructure and optimized mechanical properties, including a minimum tensile strength of 515 MPa, elongation ≥35%, and sustained performance in high-temperature and high-pressure environments. The ASTM A312 TP316Ti seamless pipes feature strict dimensional tolerances (outer diameter ±0.15mm, wall thickness ±10%), meeting the demanding requirements of industries that require thick-wall pipes with exceptional corrosion resistance and thermal stability.
