Alloying steel brings about changes in its characteristics. Not only the properties of alloyed steels higher, but their longevity is also better. Despite being classified as a low alloy grade, the 20mncr5+Hh material Properties are significantly higher than conventionally used carbon steel alloys. Cheaper than most high alloy steels and stainless steel grades, this low alloy steel is case hardened for several reasons. Case hardening the 20MnCr5+HL steel Cold Rolled Round Bars improves the surface hardness of the alloy, keeping the core of the material softer. Because the material has been treated by case hardening, the surface becomes tougher, which means the alloy is suited to engineering purposes that require higher surface hardness properties. The core tensile strength properties of the AFRON 20MC5 Hot Rolled Round Bar are valued to be estimated between a range of 1000 N/mm² – 1300 N/mm². Since the alloy resists wear, the polishability of the 20mncr5 Round Bar is considered to be good. The microstructure of this low alloy steel shows a smaller grain size. The benefits of having a small grain size are appreciated because it optimizes the ductility of the IS 20MnCr1 Square & Black Bars. The fatigue strength of this alloy is also considered to be good. With the content of carbon being relatively lower in the alloy, the weldability properties of the Carbon Steel 20Mncr5 Hex bar are considered to be good.

From 5mm to 250mm diameter Carbon Steel 20Mncr5 Hex bar offer high strength 20MnCr5+HL steel Cold Rolled Round Bars at factory price
