Product Description

5140 quenched and tempered qt steel round bar


5140 steel is a Chromium through-hardening steel of medium hardenability. It is a general purpose high-tensile steel with medium strength level and good impact properties.

 

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.

 

5140 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
