Typical Mechanical Properties – for guidance only

Typical Mechanical Properties – for guidance only

Water or oil quenched at 830°C – 850°C and tempered between 540°C – 680°C

 upplied to chemical analysis only unless ordered in the heat-treated condition

Welding procedure:

Low hydrogen electrodes are recommended. Pre-heat at 200°C –300°C and maintain during welding. Cool slowly in ashes or sand etc and stress relieve when this is possible. Welding details for guidance only.

HEAT Treatment:

Forging:

Heat to 1250°C Hold till uniform

Minimum forging temperature 850°C Cool in still air

Annealing:

Heat to 800°C – 850°C -- Cool in furnace

Normalising:

Heat to 870 °C - 920 °C -- cool in still air

Stress Relieving:

Heat to 550°C – 660°C---Cool in still air

Hardening:

Heat to 820°C – 860°C --- Quench in oil or water

Flame and Induction hardening:

Heat quickly t othe required case depth at  830°C – 860°C and quench immediately in water or oil. temperature at  will reduce stresses in the case with minimal effect on its hardness. all de-carburised surface material must firstr be removed to ensure best.

Delivery Condition

Forged + Annealed + Machining (Peeled/Turned)

Size Availability

We offer different types of steels, including square, flat and round.

Both electric steel and electroslag steel/Standard – Non-standard are available.  

Dimensional Tolerance:

The dimensional tolerance and the straightness of black “as forged” bar

can vary quite considerably. Bars should always be checked prior to machining to ensure that they will clean up as required.

Quality Assured Supply:

1045 carbon steel is supplied in accordance with our ISO 9001 : 2008 registration.

Typical Applications:

Axles, bolts, connecting rods, studs, rams, pins, rolls, spindles, ratchets, crankshafts, torsion bars, sockets, worms, light gears, guide rods etc.
