Application

40 steel is widely used in piston rods, gear wheels, crankshafts, ring gears, flywheels, axles and bolts. It also features in medium-sized components like long axles, feed rods, cogs, etc, that are used in components for pipe fittings following preliminary quenching, which is conducted during the assembly of agricultural vehicles. 40 steel is used in fastenings for pipelines/boilers for thermal and nuclear power plants, and block/connecting components for turbines.


Welding

40 steel has limited welding capacity (to achieve a high-quality weld, the steel must be pre-heated before and annealed after the welding). The welding methods for this steel are manual-arc, automatic-arc and electroslag welding. Limitless contact welding can be applied.
