MECHANICAL ALLOY STEELS

They are machine-made steels that are hardenable, particularly in terms of carbon content, and exhibit high toughness at a specified tensile strength at the conclusion of the curing process.

Different machinery and engine components, forging parts, various bolts, nuts and studs, crankshafts, axles, control and drive parts, piston rods, various shafts, gears, etc. have excellent mechanical qualities as a result of the curing (hardening and high degree of tempering) process.

They are widely utilized, particularly in the fabrication of components.
