1045 quenched & tempered qt steel bar  

1045 quenched & tempered qt steel bar   1045 is a medium carbon steel for mechanical engineering and automotive components manufacturing. It can get high strength and high hardness after quenched and tempering. The similar material includes C43, C44, C45E, CK45, SAE1045, 080A42, S45C 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.   1045 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…
