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…
As the name implies, people called the steel tube or pipe used for mechanical applications mechanical tubing, sometimes the steel pipe for structural applications also be referred to as the mechanical tubing. It is characterized by high precision, smooth internal and outside uniformity, high strength, high-pressure resistance, low cost and long service life, can be…
Alloy steel is divided into silicon-manganese carbon steel, stainless steel, high-speed steel and silicon electric steel according to the different elements. Before the invention of high-speed steel, the cutting tool material in the metal processing industry is mainly high carbon steel, but the cutting speed is relatively slow, usually below 10m/min. The cutting speed of…
Chrome-Moly steel, or Chromoly steel, is a type of low alloy heat resistant steel, also known as medium temperature hydrogen resistant steel, which has better mechanical properties and hydrogen resistant properties at room temperature and high temperature. The main alloying elements in steel are molybdenum, chromium, vanadium, silicon, boron, etc., among which Cr(≤ 1O %)…
