We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
These coils are known for their excellent **fabrication characteristics**, such as **formability**, **weldability**, and **dimensional accuracy**, making them ideal for rolling into **tubes, flanges, and pressure parts**. With a **minimum tensile strength of 415–585 MPa** and outstanding corrosion resistance, Grade 12 coils comply with both ASME and ASTM specifications (typically aligned with **SA387/ASTM A387 Grade 12** plate chemistry).
Alloy Steel Grade 12 Coil has a wide application in industries as it has great mechanical properties along with resistance against heat and corrosion. It is mostly applied for the production of heat exchangers, pressure vessels, boilers, and equipment used in power plants as it is capable of handling high pressures and temperatures. It is applied in the chemical and petrochemical industries in processing equipment as well. Moreover, its high strength and toughness render it applicable for structural use, automotive parts, and pipelines in severe conditions.
