Applications

With its high wear resistance 1.8519 steel is used widely in the engineering and automotive industries. Suitable for components with medium and large cross sections which require high tensile strength and good toughness. Typically used for in gear and engine construction for components such as crankshafts, connecting rods, steering knuckles, screws and bolts.

Carbon 0.27-0.34% Chromium 2.30-2.70%
Manganese 0.40-0.70% Molybdenum 0.15-0.25%
Sulphur 0.035% max Silicon 0.40% max
Phosphorous 0.025% max Vanadium 0.10-0.25%

Heat slowly, allowing sufficient time for the steel to become heated through. Begin forging at 1050°C. Do not forge below 930°C reheating if necessary. After forging, cool very slowly.

Heat to 860-900°C. Soak well and allow to cool in the air.

Heat uniformly to 680-720°C.  Soak well, cool slowly in the furnace.  Hardness after annealing is 248 HB max.

Heat uniformly to 840-880°C until heated through. Quench in oil or water.

Heat carefully to a suitable temperature, selected by reference to a tempering chart or table (usually between 540-680°C). Soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in the air.

Tools machined from pre-hardened 1.8519 may be nitrided to give a wear resistant case of approximately 800 HV surface hardness.

 

Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of 1.8519 tool steel.
