ASTM A335 P12 Seamless Pipe & Tubes

ASTM A335 P12 Seamless Pipe & Tubes

Meta Aerospace stands as a prominent ASTM A335 P12 Seamless Pipes & Tubes Manufacturer and Supplier in India, offering a diverse range of products tailored to various types, shapes, and sizes. Crafted with a composition comprising carbon, manganese, phosphorus, sulfur, silicon, 0.8% chromium, and 0.45% molybdenum, our seamless pipes exhibit excellent welding capabilities, facilitated by their low carbon content. However, when welding with high-carbon pipes or other steel materials, preheating and post-weld heat treatment are necessary to prevent welding cracks.

The dimensions of our SA335 GR P12 pipes vary, with nominal bore sizes ranging from 1/8NB to 24NB and wall thicknesses from 2mm to 14mm. Outer dimensions span from 19.05mm to 114.3mm, with pipe lengths available in single random, double random, or cut-to-length sizes up to 16000mm. Our pipes feature different endings, including threaded, plain end, and beveled endings.

Distinguishing between P11 and P12 pipes lies in their chemical composition. While P11 contains up to 1.25% chromium and up to 45% molybdenum, P12 may have up to 1% molybdenum. This variance results in differing corrosion resistance and hardness in the ASTM A335 P12 Seamless Pipe. Both grades boast a minimum tensile strength of 415MPa and a minimum yield strength of 205MPa.

To enhance the hardness of Alloy Steel P12 Pipes, various heat treatment methods such as full or isothermal annealing, normalization, and tempering are employed.

At Meta Aerospace, we are dedicated to delivering superior-quality ASTM A335 P12 Seamless Pipes & Tubes to meet the diverse needs of our customers.
