Stainless Steel Seamless TubesAlloy Steel Astm A335 P12 Seamless Pipes
Alloy Steel ASTM A335 P12 Seamless Pipes are formulated with a precise composition including carbon, manganese, phosphorus, sulfur, silicon, 0.8% chromium, and 0.45% molybdenum. With a maximum carbon content of 0.015%, these pipes are classified as low carbon steel. As Manufacturers, Suppliers, Stockists, and Exporters, Metinox Overseas stands at the forefront, offering a diverse range of ASTM A335 P12 Seamless Pipes in various types, shapes, and sizes to meet industry demands.
The welding process for these pipes is straightforward, 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 primary difference between P11 and P12 pipes lies in their chemical composition. P11 pipes contain up to 1.25% chromium and up to 45% molybdenum, while P12 pipes can have up to 1% molybdenum. This variance imparts different corrosion resistance and hardness to ASTM A335 P12 Seamless Pipes. 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, normalized, and tempered processes are employed.
