D2 Tool Steel
D2 is a high carbon high chromium tool steel grade offering very high wear resistance and toughness.
D2 tool steel hardens in air with a low order of movement and offers a measure of corrosion resistance when polished. Commonly used for tools operating under conditions of severe wear and abrasion or as an alternative to oil hardening tool steel grades when long runs are required.
01 Tool Steel
The 01 grade is an oil hardening tool steel supplied in the annealed condition. O1 tool steel offers good durability, gives excellent wear resistance and holds a good cutting edge. With these properties, it is an excellent general-purpose tool steel often used where the expense of a high carbon high chromium tool steel would not be justified.
A2 Tool Steel
A2 is air-hardening tool steel which after heat treatment offers a high abrasion resistance coupled with toughness. Due to its lower chromium content, the wear-resistant properties of A2 are not as great as those to be found in high carbon, high chromium steels such as D3 and D2 but it is much easier to machine than the latter specifications and can be ground to a cutting edge which is less liable to crumble in service. Where tools of a large mass are being produced A2 tool steel, being an air-hardening quality, is more suitable than the oil or water hardening tool steels.
EN24T Tool Steel
EN24 is usually supplied in the T condition with a tensile strength of 850/1000 N/mm2. EN24T steel is a popular grade of through-hardening alloy steel due to its excellent machinability in the "T" condition. EN24T is used in components such as gears, shafts, studs and bolts, its hardness is in the range 248/302 HB.
H13 Tool Steel
H13 is a reliable hot work steel and is suitable for a wide variety of applications. It combines very good red-hardness with toughness, tools may be water-cooled in service. H13 may be cold-hobbed in the annealed condition.
P20 Tool Steel
P20 is an alloy tool steel which offers good machinability even in the hardened and tempered (Brinell 300) condition. This steel gives an excellent polished finish and is one of the most widely accepted specifications for machine cut plastic moulds and casting dies. P20 is often supplied in the hardened and tempered condition ready for machining. In this condition, it gives excellent wear resistance but if maximum surface hardness is required for compression moulding plastic dies or similar tools, the steel can be case hardened or nitrided.
