Alloy Steel Grade 11 Coil is a ferrous metal composed primarily of iron, small quantities of manganese and carbon. It has high tensile strength and good weldability, making it suitable for heavy-duty applications such as pipes, valves, pumps and automotive components. The coil form is heat treated to provide excellent mechanical properties such as impact resistance and hardness. Grade 11 has the highest chromium content in its alloy steel range, increasing its corrosion and oxidation resistance while providing superior wear resistance levels. Additionally, increasing carbon content in this grade allows for higher hardenability than other grades, meaning it can be cold-worked at lower temperatures without cracking or degrading mechanical properties.
Alloy Steel Grade 11 Coil is noted for its excellent strength, creep resistance and toughness. It provides higher yield strength when compared to conventional steels. Due to good formability, it is used in the construction of bridges and for making automobile parts such as engine blocks, axles, shafts and more. This coil has a low carbon content that makes welding easier without suffering from cracking or embrittlement due to heat treatment. Its exceptional corrosion resistance has made it popular in chemical processing industries where carburization is an issue under high-temperature conditions.
