Product Description

4137 quenched & tempered QT steel round bar


4137 steel is a Chromium-Molybdenum steel of medium hardenability which is mainly used in oil industry. It is a general purpose high-tensile steel with medium strength level and good impact properties. Through-hardening like quenching and tempering, 4137 material will get high tensile strength, high yield strength and high hardness. 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.

 

4137 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
