Constructional Steel



  • EN-18 (C-35 - 45, AISI - 1040)
    • Application: Crank shafts, automobile axle beams, connecting rods, lightly stressed gears and other moderately stressed parts of motor vehicles and general engineering works.

 

  • EN-19 (AISI 4140, 42CrMo4 ) 
    • Application: Axle and crank shafts, gears, connecting rods, studs, bolts, propeller shaft joints. Suitable for heat-treated parts where high tensile and impact strength is required

 

  • EN-24 (AISI 4340, 34CrNiMo6 )
    • Application: Aircraft and heavy vehicle crank shafts, gear shafts, connecting rods, studs, chain parts, clutches, propeller shafts, cam shafts, spindles, screws, pinion, tappets, boring bars. Suitable for heat treated components having large sections and subject to exacting requirements.
