ASTM 5130 / EN 28Cr4 1.7030 Alloy Steel Bar / Rod Forged 130-1600mm
INTRODUCTION
ASTM A29/A29M 5130 alloy steel is a quenching and tempering steel.
5130 can also be used after normalizing. After the treatment, ASTM
A29/A29M 5130 round bar 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.
APPLICATIONS
This alloy is used for highly stressed parts with medium cross
sections for automotive and general engineering applications, such
as forged camshafts and gears, gear shafts, bushings and connecting
rods.
