41Cr4 quenched and tempered qt steel round bar  

41Cr4 quenched and tempered qt steel round bar 41Cr4 steel is a Chromium through-hardening steel of medium hardenability. It is a general purpose high-tensile steel with medium strength level and good impact properties.   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…
