4145 quenched & tempered qt steel round bar

4145 quenched & tempered qt steel round bar

AISI 4145 steel is a Chromium-Molybdenum through-hardening steel of medium hardenability widely used thoughout oil and gas industry. It is a general purpose high-tensile steel with medium strength level and good impact properties. It also has one upgraded steel material 4145h which improve the hardenability and is more common used in high strength condition. 

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 Tie Rods, Marine Sheet Pile Tie Rod For Wharves, Post Tension Bar For Bridge, Tie Bar Construction, Structural Steel Tie Bars and high strength required steel shafts etc.
