c45 quenched & tempered qt steel bar  

c45 quenched & tempered qt steel bar C45 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. Heat treated steel bar - quenched and tempered steel bar can be used to produce High Strength Marine Anchor Bolt, Wind Turbine Anchor Bolt, Mining And Tunneling Rock Bolt, High Strength Steel Bolts, Sheet Pile Ti…
