Steel grade 25 is used to make flanges, bolts, axles, shafts, latches, washers, levers, other fastenings and non-critical parts, e.g. screws, bushes, etc. This steel is widely used for the manufacture of parts subjected to thermochemical treatment (carburizing, nitrocarburizing, nitriding, boriding), which provides high surface wear resistance and hardness with low core strength.
No welding restrictions except for thermochemically treated parts. Welding methods: manual metal arc welding, submerged arc welding, electric resistance welding.
