STAINLESS STEEL 347 SEAMLESS TUBING

Neeka Tubes is a global manufacturer and supplier of Stainless Steel 347 Seamless Tubing, offering premium-quality tubing solutions for various industries. SS 347 seamless tubing is a stabilized austenitic stainless steel alloy with high resistance to intergranular corrosion and high-temperature use. This tubing is ideal for applications requiring superior strength, durability and oxidation resistance. We have tubing available in annealed and pickled, bright annealed, polished and cold-drawn conditions.Our SS ASTM A312 TP347H Seamless tubing contain chromium (17-20%) and nickel (9-13%), enhancing its corrosion resistance. The addition of columbium (Cb) and tantalum (Ta) improves its strength at high temperatures. This alloy has a tensile strength of 75 ksi (515 MPa) and a yield strength of 30 ksi (205 MPa), with an elongation of 40%. Our tubing conforms to ASTM A213, A269, A249, A511, A554 / ASME SA213, SA269, SA249, SA511 and SA554 standards, we have sizes from 1/2″ OD to 8″ OD with thicknesses ranging from 0.3mm to 50mm.
