Understanding of high speed steel&tungsten steel

Today we are going to learn about high speed steel&tungsten steel, thus you

can make better use of the two kinds of materials.
About high speed steel
High speed steel (HSS) is a kind of tool steel with high hardness and high

wear resistance and high heat resistance, also known as wind steel or steel,

it means even quenching cooling in air can be hardened, and very sharp. It's

also called white steel. It mainly used in the manufacture of complex thin

edge and impact resistance metal cutting tools, but also the manufacture of

high temperature bearings and cold extrusion mould, such as turning tools,

drills, hob, machine saw and the high demand of the mould.

About tungsten steel
Tungsten steel (carbide) has a series of excellent properties of high

hardness, strength and toughness, heat resistance and corrosion resistance,

etc, especially the features of high hardness and heat resistance , even at

a temperature of 500°C it remained unchanged, at 1000°C it still have high

hardness. Widely used as the material, such as turning, milling, drilling,

boring knife and so on . The cutting speed of the new type cemented carbide

is several hundred times of that of carbon steel.
