O1 tool steel

 General purpose oil hardening tool steel which hardens at a relatively low temperature with
 minimum distortion.

D2 tool steel

 High carbon high chromium tool steel giving a good hardness with added toughness. This steel
 can be vacuum hardened when minimum distortion is required.

D3 tool steel

 Similar steel to D2 tool steel, this steel attains a slightly higher hardness and has good abrasion
 resistance.

D6 tool steel

A2 tool steel

 Air hardening tool steel which is easier to machine than D2 or D3 but offers high abrasion
 resistance with good toughness.

H13 tool steel

 5% chromium hot work tool steel. This steel is air hardening with very little distortion. H13 tool steel
 can be vacuum hardened and may be water cooled in service.

S1 tool steel

 Excellent tough and shock resisting tool steel, with good abrasion resistance. When hardened 
 S1 has a good cutting ability with great toughness

P20 tool steel

 Pre-hardened high tensile steel which is readily machineable. P20 can also give a higher hardness
 than its supply condition and can be nitrided.

1.2767 tool steel

 4.25% nickel steel, which achieves a good through hardness. 1.2767 is capable of taking a good 
 polish and is commonly used as a plastic mould steel.

M2 high speed steel

 General purpose high speed steel. M2 which offer good wear resistance and superior toughness
 and machineability.

420 stainless steel

 13% chromium stainless steel which will achieve a high hardness. 420 stainless steel
 gives a good polish and is resistant to attack from corrosive plastics.

1.2842 tool steel

 M42 high speed steel
