Product Description

4142 quenched & tempered qt steel round bar

4142 steel is a medium-carbon steel with chromium-molybdenum through heat treating to get a good strength levels and roughness.

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.
