34CrNiMo6 is a good general-purpose alloy steel that is mostly used in the manufacturing of various engineering parts. It can be heat-treated to produce lots of tensile strengths combined with resistance to shock and good ductility. It has good hardenability, which means it is fairly wear-resistant, and it provides good impact values at low temperatures. 

Alloy Steel Bars

Bars are frequently made available in the tempered and hardened condition with a tensile strength that exceeds 1000 N/mm2, depending on the size of that particular section. The material is readily machinable and therefore, the components can be used without any further treatment and the costs associated with that treatment. Bars are also available in a softened state which provides increased machinability, although they require hardening and tempering first.

What Are its Uses?

Uses for this type of steel include connection rod bolts, push rods, studs, breech mechanism parts, high-temperature bolts in steam and oil-refining installations, pinion sleeves, mandrel bars for the manufacturing of tubes, and all types of machine tool parts, such as slide cams, spindle gears, and power transmission gears.

Most companies that offer all types of alloy steel manufacture services will provide this grade of steel, which contains nickel, chromium, and molybdenum, giving it its hardness and toughness, not to mention its ability to inhibit temper brittleness and even reduce grain size. This is a multipurpose alloy steel that you can find numerous uses for.
