4130 / E4130 Chromium-Molybdenum Alloy Steel

Description

4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint. The alloy can be hardened by heat treatment. This grade responds to nitriding for excellent wear and abrasion resistance.

4130 HT (Heat Treated)
4130 QT (Quenched & Tempered)
Chrome Moly
E4130
E4130 HT (Heat Treated 26-32RC)
StarDOM 4130 (tm)

Applications

Typical applications for 4130 low alloy steel include. structural use such as aircraft engine mounts and welded tubing applications, shafting, alxes, gears, sprockets, pston rods, reamer bodies, well-head components, tool joints, fasteners, hand tools.
