Alloy Steel Round Bar

ASTM A182, F5, F9, F11, F12, F22 & F91 Hot Rolled Alloy Steel Rounds and 42crmo4 Cold Drawn Bright Bars Manufacturer in India

Alloy Steel Round Bars can be found in various grades like ASTM A182, F5, F9, F11, F12, F22 & F91 for applications where high temperature oxidation resistance is necessary and in other applications where high temperature strength is required. 42crmo4 Bar has high chromium content which is so beneficial to the wet corrosion resistance and is also highly beneficial to their high temperature strength and resistance to scaling at elevated temperatures. SAE 4140 Rod performs well at high temperatures, which means they have high creep resistance and strength at high temperatures. Hot Rolled Alloy Steel Round Bars exhibits superior physical and mechanical properties are required in applications such as annealing of aerospace and medical components to critical specifications, voluminous production of components for brazing with controlled atmosphere furnaces, and heat treatment of large aerospace components in vacuum furnaces.

Alloy Steel Round Bar is a long, cylindrical alloy bar stock that has many industrial and commercial applications. Its most common application is shafts. It has variety of alloying elements which improves its mechanical properties. It has great strength, formability, and hardenability. SA 182 F91 Rod has high mechanical durability, high toughness and strength, superior electrical and thermal conductivity and low coefficient of thermal expansion. ASTM A182 F12 Flat Bar is a flat, rectangular section with square edges varying in sizes. It is suitable for a wide variety of applications and is distributed into the engineering, construction, manufacturing, fabrication, mining, grating, and many other industries. Its versatility is the primary reason it is usable through various industries, along with its excellent strength and formability.
