DIN 1681 GS‑45 Heat‑Treated Steel: Superior Strength for Heavy‑Duty Applications

GS-45, for castings without special stress: application in the heavy mechanical engineering and gearing manufacturing, in the manufacturing of agricultural machines and vehicles, in the construction of tools and processing machines, e.g. casings, hubs, bearing covers, bearing rings, bushes, pillow blocks, plates. With statical or dynamic stress: application for clutch carriers, bearings, rockers, commutator hubs, rib steel base plates, pins, hollow shafts, rope sheaves, front walls, centre pivots. Application for temperatures between -10 and +300 °C.
