Applications |
Used in the heat treated condition for a great variety of components in vehicle and for general engineering where low mechanical properties and small sections of the heat treated articles are involved. The grades with higher "C" content are mainly applied for parts subject to wear in the normalised state: brake, camshaft, axles, spring bolts, roller - bearing for bridges, gear driving wedges, etcs

Applications |
Used in the heat treated condition for a great variety of components in vehicle and for general engineering where low mechanical properties and small sections of the heat treated articles are involved. The grades with higher "C" content are mainly applied for parts subject to wear in the normalised state: brake, camshaft, axles, spring bolts, roller - bearing for bridges, gear driving wedges, etcs

Applications |
For heavy duty gearing, air craft and transport vehicle construction. M-ECNMo 170 is well suited for parts where direct hardening is preferred. |
This class of steel possess high tensile strength of core coupled with high toughness and used for components in vehicles and air crafts as well as for general engineering purposes, where blows and shocks are involved. In case where exceptionally high toughness is required, our brands M-ESS Spl and M-PPA are economically used. |

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 |
