ASTM A29/A29M 5130 alloy steel is a quenching and tempering steel. 5130 can also be used after normalizing. After the treatment, has excellent strength and hardenability.

Based on the properties, 5130 round bar is mainly applied to some important parts which work in abrasion and high impact and heavy load condition, such as shaft, small axles,equalizer beam,jointed arm,connecting rod,running pulley and so on.

ASTM A29/A29M 5130 alloy steel can be produced into hot rolled round bars and square bars, cold-drawing bars,forged bars. We henan KUNFENG can supply ASTM A29/A29M 5130 all of shapes.
