M VCL135 | M VCL140 | Applications | Used where extra-ordinary high toughness is required. Their tendency to temper brittlleness is eliminated by rapid quenching in oil or water after hardening. Therefore temperature of 400° C should not be exceeded if a subsequent stress relieving is applied.
For heat treated components of large sections and subject to very exacting requirement. Due to Molybdenum contents, these steels are insusceptible to overheating and free from temper brittleness while permit higher stress relieving temperatures. Mainly used in the construction of air crafts and heavy vehicle for crank shafts, connecting rods, gear shafts, chain parts, clutches, propeller shafts, camshafts, cardon shatfs etc. | For treated parts of medium cross section where high tensile and impact values are required, combined with high endurance bending strength, gears, vehicle engine crank-shafts, stub axles, connecting rods, spindle, transmission gears, shafts for pumps and gearing, etc. If good weldability is also required, then M-VCL125 is recommended | Forging Temp. °C | 1200-850
