Forging A2 Tool Steel

The first high speed steel came to be known as t1 which had 4 cr and 18 w tungsten.

Forging a2 tool steel.

A2 tool steel properties. Do not continue forging below 1700 f 927 c. It contains chromium and molybdenum with a relatively high 1 carbon content and is capable of deep hardening from air quench so as to minimize distortion. This alloy is one of the cold work medium air hardening type tool steels.

Small simple forgings can be cooled slowly in lime. These tool steels should not be forged below 899 c 1650 f. It seems that whatever i try i can t get a nice smooth finish on the lathe. S7 tool steel is a versatile formulation suitable for both cold and hot work service.

The best practice for large forgings is to place them in a. It is heat treatable and will offer a hardness in the range 57 62 hrc. A2 is a 5 chromium steel which provides high hardness after heat treatment with good dimensional stability. Reheat as often as necessary.

Shut the forge off and leave the door closed allowing the steel to soak up the heat of the forge without the added oxidation of the forge blast. It has a relatively low carbon concentration compared to d2 and a2 steels 0 45 0 55 and significantly less chromium 3 00 3 50. Forming of a2 tool steels is carried out by machining or hot forging. I have tried everything hhs tool bits with various angles and radius different spindle rpm and feed rate different types of cutting fluid.

Tool steel a2 principal design features. A2 tool steels are heated slowly to 788 c 1450 f and this is followed by increasing the temperature to 954 c 1750 f. A2 tool steel is an air hardening cold work steel. I am working on a project that includes a2 tool steel parts and i have no experience of working with a2.

Forging a2 tool steel forges very much like a high speed steel. Bring the forge up to a strong heat run the forge at 10 12 psi for about 5 minutes place the tool steel into the heating chamber and heat the steel for about 30 40 seconds. S7 tool steel properties.
