S1 Tool Steel

BS4659 BS1 is a high duty shock resisting alloy steel/" target="_blank" class="keylink">tool steel. In the hardened condition S1 heat resisting tool steel combines great hardness with good toughness and shock resisting properties.

TYPICAL ANALYSIS
C.	Si.	Mn.	Cr.	V.
0.50%	0.80%	1.50%	2.50%	0.20%

Forging:

Heat slowly and uniformly to 1000°C. Forge within a range of 1000/800°C, reheating if necessary. Cool slowly (preferably in a furnace) to avoid setting up stresses.

Annealing:

Heat uniformly to 770°C, equalise, then furnace cool.

Stress Relieving:

If machining operations have been heavy or if the tool has an unbalanced section, remove stresses before hardening by heating up to 700°C, equalise, then cool slowly.

Hardening:

Pre heat the S1 steel/" target="_blank" class="keylink">tool steel to 650°C and thoroughly soak. Continue heating to the final hardening temperature of 900/950°C. Allow sufficient time for the component to be heated through. Quench in oil.

Martempering:

Martempering is an alternative hardening procedure which may be used when suitable salt bath equipment is available.

Tempering:

Heat uniformly and thoroughly at the selected tempering temperature and hold for at least one hour per inch of total thickness.
