Stainless free cutting steel or stainless machining steel is a kind of alloy steel in which sulfur, lead, calcium, selenium, tellurium and other free cutting elements are added to improve its cutting ability. These free cutting element compounds lubricate the cutting tool and reducing the cutting resistance of the stainless steel, thereby reducing the surface…
Element Molybdenum(Mo) was first used as a cost-effective alternative element for tungsten in tool steels and high speed steels(HSS). Mo has about half the atomic weight of tungsten, and 1% molybdenum is about the same as 2% tungsten. Mo improves the hardness and wear resistance of tool steels, and promotes the formation of an optimal…
Matrix steel generally refers to the steel whose chemical composition is the same as that of the matrix in the quenching structure of high sped steel(HSS). That is, adding a small amount of alloying element or changing carbon content appropriately to the matrix composition of HSS to improve the performance of the steel to meet…
As we know, tool steels can be divided into carbon tool steels, alloy tool steels and tungsten carbide steels, all of which can be used to make tools, cutting tools, dies and measuring tools. Carbon tool steels have a good cold and hot workability, the highest quenching hardness can reach HRC66 ~ 67, but usually,…
Tungsten steel, also known as tungsten carbide, is a sintered composite metal containing some metal carbide, mainly including tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide. The tungsten steel matrix is composed of the hardening phase and the bonding metal. The grains of the carbide phase usually 0.2-10 microns, are bound together by…
