Product Description

B3 quenched and tempered qt grinding steel rod

B3 steel is a high carbon and high manganese Chinese standard steel. B2 steel grinding rod is used for rod mills in mines, cement plants, power station, chemical industries etc. Especially after quenching and tempering, the hardness can reach 65HRC max.

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.

B3 material quenched and tempered q&t steel bar we supply includes following advantages:

The wear resistant steel grinding rod is about 2 times stronger than hot rolled  bars.

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
