20MnB4 steel round bar and wire rod

20MnB4 steel round bar and wire rod

20MnB4 steel material is belong to carbon steel material with low carbon content, but it also have small alloy element content such as Mn and Boron. In general, without heat treatment, 20MnB4 steel bar is not required to guarantee the mechanical properties. But it can be quenched and tempered to reach different strength to meet different manufactuers' usage requirements. 20MnB4 steel bar is usually used to produce chains, wheel hub and some wear parts in machineries. Mostly, 20MnB4 steel is in wire rods, so the diameters are not bigger than 30mm. With 20MnB4 wire rods, we can produce 20MnB4 Cold Drawn Steel Bar and Quenched And Tempered Steel Bar after straightening the wire rod to straight plain bar.

20MnB4 steel material chemical composition:

Except 20MnB4 steel material ,we can produce many kinds of steel grade Cold Drawn Steel bar, Annealed Steel Bar, Normalized Steel Bar, quenched and tempered steel bar, any demands. feel free to contact.
