STAINLESS STEEL is a type of steel resistant to corrosion and wear, given that the chrome which it contains (minimum 10.5% of chrome) has a great affinity with oxygen and reacts with it thus avoiding corrosion of the iron.

High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is often used in power-saw blades and drill bits.

Tool steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. Their suitability comes from their distinctive hardness, resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated temperatures. Tool steels are suited for use in the shaping of other materials.

Through the addition of particular alloys, low-alloy steels possess precise chemical compositions and provide better mechanical properties than many conventional mild or carbon steels. These alloys typically comprise 1 to 5 percent of the steel’s content and are added based on their ability to provide a very specific attribute.
