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.

According to the market needs, henan KUNFENG supply the oversea markets for ASTM A29/A29M 5130 hot rolled round bars OD 6mm -80 mm and 5130 forged round bars OD 80 mm - 1200 mm, also ASTM A29/A29M 5130 forged square bars OD 100- 1200 mm. The OD tolerance is about 0-3 mm and length tolerance is about 0-20 mm.

s are usually produced under the followed procedures: EAF arc furnace + LF purify affinage + VDF + ingot steel(bottom gating /argon) + forged + annealing + black polishing (turnery) + Sep 1921-C/c,D/d,E/e UT test + smooth edges with sawing .
