20CrNiMo2-2 quenched and tempered qt steel round bar
20CrNiMo2-2 steel is a common case-hardening steel of nickel, chromium and molybdenum. It has good strength and other properties. It is usually used to produce light or medium stressed components and shafts requiring high surface wear resistance. The similar standard materials include 8620,20CrNiMo2-2, SNCM220 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 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.
