Detail Information

Application of 1.6510 steel:

The steel is suited to production of highly stressed components of large cross section for aircraft, automotive and general engineering applications, such as forged propeller shafts, connecting rods, gear shafts, crankshafts and landing gear components.

Heat treatment of 1.6510 steel:

Annealing: Austenitize at 1525ºF (830ºC) and slow cool from 1280 to 1200ºF (iso anneal) to give coarse pearlite structure for optimum machinability.

Normalizing: At 1600ºF (870ºC) followed by air cool.

Hardening: from 1525-1575ºF (830-860ºC) and oil quench for thin, intricate shapes, water quench for large, simple shapes.

Tempering: from 1000-1250ºF(540-680ºC) as per required properties.

Machinability of 1.6510 steel:

The steel may be readily machined, preferably from a coarse pearlitic structure.

Weldability of 1.6510 steel:

Pre-heat and post-weld stress relief are recommended for welding of this alloy. Welding should not be carried out in the hardened and tempered condition.
