Special Alloy Steel Solid Bar AISI4140 OD 1-1/2" To 15" Length 6m

Special alloySteel AISI140 Introduction

AISI 4140 belongs to ultra-high strength steel, implemented standard: ASTM_A29/A29M (forged and cold-worked carbon steel and alloy steel bars)

AISI 4140 has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and resistance to multiple impact

after quenching and tempering, and good impact toughness at low temperature. The steel is suitable for manufacturing large and medium-sized

plastic moulds which require certain strength and toughness.

The chemical composition of AISI 4140 is shown below:

Scope of application:

High strength, hardenability, good toughness, small deformation during quenching, high creep strength and durable strength at high temperature.

Used in the manufacture requirements higher than 35CrMo steel strength and conditioning section more large forgings, such as locomotive

traction with the big gear, supercharger drive gear, pressure vessel, rear axle, gear load connecting rod and a spring clip, can also be used to

under 2000 m deep well of oil drill pipe joint and the fishing tool, and can be used for bending machine mould, etc.
