Product Description

40Cr quenched and tempered qt steel round bar

 

40Cr steel is a Chromium through-hardening steel of medium hardenability. It is a  a steel for quenching and tempering recommended to produce high strength components lower than 42CrMo4 material. It can be min hardness 52HRC after induction surface hardening. The similar materials includes 41CrS4, SS2245, 530M40, 530H40, SCR440, 42C4, 1.7035, 1.7039, 40Cr etc.

 

Quenching and Tempering, abbreviated as Q&T is a king of processing that strengthen or harden steel bars by heating the materials and then cooling in water, oil or other liquid medium, that rapidly the change from austenite to perlite to get the proper properties for various usage. The quenched & tempered steel bar materials are usually with carbon from 0.30% - 0.60%, it is widely used as merchant bars in components of various machines.

 

40Cr material quenched and tempered q&t steel bar we supply includes following advangtages:

Consistent mechanical properties

Deep mechanical properties (from surface to the center according to your requirement)

Even hardness on the whole bars/Tougher and Increased strength

No brittle, UT testing/Precision size tolerance/Good straightness

Good Roughness/Professional technical service/Competitive price/Fast delivery
