Pre-hardened plastic mould steels are widely used for manufacturing mould for plastic because of their four main properties and characteristics:Wear Resistance Corrosion, Resistance Mirror, Finish ability,Surface Work ability. These steels are quenched and tempered before being manufactured into mould for plastic, therefore the deformation and cracking of mould resulted from heat treatment can be avoided.

2. Hardness and toughness: plastic mould steel needs to have a good balance between hardness and toughness. It should be hard enough to withstand the production of numerous plastic products but also tough enough not to break or crack easily.
3. Corrosion resistance: plastic mould steel should have excellent corrosion resistance properties, as it is frequently exposed to moisture, heat, and other harsh conditions during use.
4. Machine ability: plastic mould steel should be easy to machine and work with during the manufacturing process.
5. Heat treatment: plastic mould steel needs to undergo an appropriate heat treatment process to achieve the desired properties for specific applications.

Hot working tool steels are used in the hot-forming of work-pieces made of iron and non-ferrous metals as well as alloy derivatives at high temperatures. They are utilised in processes such as pressure die casting, continuous casting, extrusion and drop forging as well as in tube and glass manufacturing.

Cold working tool steels are high carbon steels that contain alloy additions of tungsten, manganese, chromium and molybdenum, which increase the hardenability of the steels. The high carbon content produces adequate wear resistance for short run applications. Cold work tool steels are used for cutting and pressing tools, for dies and knives, for stamping and drawing tools, hobs, thread rolling tools and in many other applications due to their typical properties – high hardness, good toughness and compressive strength and high wear resistance.

Bearing steels are used for ball and roller bearing applications and are comprised of low carbon (0.10 to 0.20% C) case-hardened steels and high carbon (-1.0% C) through-hardened steels.
