AISI 4140/SCM440/42Crmo4 Hot Rolled Steel Bar , Alloy Steel Round Bar ,Tool Steel Bar

 

Description:4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).
4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties.
Pre hardened and tempered 4140 can be further surface hardened by flame or induction hardening and by nitriding.

 

APPLICATIONS:

It is the most commonly used of the high tensile steels with a wide range of applications in automotive, Gear and Engine construction, Crankshafts, Steering knuckles, Connecting rods, Spindles, Intermediate gears, Pump and Gear shafts, Axles, Nuts and Bolts, bearing, gear, transmission gear, supercharger gear, engine cylinder, spring, 1200mm-2000mm rotary shouldered connections for petroleum industry, jar knocker.
