Product Description

Owing to our immense industry experience and knowledge, we are engaged supplying a broad stock of AISI 4140 Steel Bars. The offered pipes are precisely engineered by using best quality material that enhances their durability and longevity. Used for diverse constructional applications, the gamut of AISI 4140 Steel Bars is delivered in square as well as in round shapes. Moreover, we deliver the entire range of in variegated shape, sizes and thickness.
These AISI 4140 Steel Bars feature excellent resistance to high temperatures, corrosion and other adverse conditions. The alloys we use in manufacturing these bars is cold drawn annealed steel of relatively high harden- ability. These steel bars respond well to heat-treatment and are relatively easy to machine. These bars have good strength and wear resistance, excellent toughness, coupled with good ductility, and the ability to resist stress at elevated temperatures.
