High Speed Steel Mechanical Properties

It is also called jis skh51 and din 1 3343 steel.

High speed steel mechanical properties.

It has a great impact on high speed steel wear resistance. The trs can be from 1700 mpa to 3300 mpa. Wear resistance and other properties of the high speed tool steels. Both of these properties enable hss tools to cut faster hence the name high speed and to be used for longer periods.

High speed steel hss or hs is a subset of tool steels commonly used as cutting tool material. The chemical composition of t1 tool steels is outlined in the following table. Increasing the silicon content from 0 15 to 0 45 gives a slight increase in maximum attainable tempered hardness and has some influence on carbide morphology although. When used in tools high speed steel operates at a very low thermal expansion rate of 9 7 microns per meter per degree celsius.

It can increase the red hardness of steel and wear resistance in high temperature. Molybdenum high speed steels are designated as group m steels according to the aisi classification system. Over 95 of high speed steels manufactured in the us are. It is easy to overheat control the quenching heating temperature is necessary and the heat treatment protection requirements are strict.

Tungsten exists mainly in the form of m6c in high speed steel. This article on tool steel type t1 will focus on the chemical composition physical mechanical and thermal properties and other designations of t1 tool steels. The porosity and mechanical properties of h13 tool steel processed by high speed selective laser melting takaya nagahama takashi mizoguchi makiko yonehara and hideki kyogoku process technology r d dept jtekt corporation 1 1 asahi machi kariya aichi 448 8652 japan. The shear modulus can take a value between 80 gpa to 105 gpa depending on its composition.

M2 high speed tool steel is tungsten molybdenum high speed steel with a well balanced carbon composition and high toughness. The amount of tungsten or molybdenum is the key. It also conducts heat at a very low rate. Tungsten high speed tool steels or group t steels range from t1 to t15 series.

The influence of silicon on high speed tool steel up to about 1 0 o is slight.
