When talking about circular saw blades, it is common to hear the HSS saw blade, which is one of the important types among circular saw blades. Do you know the meaning of HSS? It is the abbreviation of High Speed Steel, which is the high alloy steel containing too many different chemical elements such as carbon, tungsten, molybdenum, chromium, vanadium and others and then processed with heat treatment. When the cutting and sawing temperature is up to 600 Celsius degree and above, its hardness still maintains the original condition, no obvious down trend. According to the different chemical components, powder high-speed steel mold can be divided into common powder high-speed steel mold and high performance high-speed steel. On the other hands, according to the different manufacturing techniques, it can be divided into the smelting high-speed steel and powder metallurgy high-speed steel. In China, the common manufacturing technique is smelting while in foreign countries the powder metallurgy workmanship is the main stream. In the following article, I will introduce some basic knowledge about common powder high-speed steel, are you interested in this topic? When cutting and sawing the complicated shape material, which is difficult to be cut and sawed with common cutting tool, the high speed steel cutting tool would be the best choice. As usual, common powder high-speed steel can meet lots of the cutting needs. In daily life, it is common to find two types of common powder high-speed steel, including tungsten series high-speed steel and chillagite series high-speed steel. Tungsten series high-speed steel If you notice its number is W18CR4V, it is the typical Tungsten series high-speed steel. Its heat treatment hardness would reach up to 66HRC while its bending strength would reach up to 3500MPa. In other words, it has good performance of abrasion proof. However, as for its shortcoming, its toughness is very poor and meanwhile it is easy to be fragile and even burst, therefore the number of such high-speed steel used for high-speed steel saw blade is limited. Chillagite series high-speed steel When taking about chillagite series high-speed steel, its typical number include W6Mo5Cr4V2. As for its advantages, its carbide contained inside is thin and distributed uniformly, meanwhile, its abrasive resistance is good performance and the cost of production is also too low. Similar with tungsten series high-speed steel, its eat treatment hardness would reach up to 66HRC but its bending strength would reach up to 4700MPa, which is better than tungsten series high-speed steel. Because of these feature, it is widely use in too many tools such as broach, milling cutter, gear cutters and so on. Let me introduce Flostools to you, which is the professional Circular Saw Blade manufacturer in China. You can get Panel Saw Blades, together with Plastic Saw Blades at here with affordable price.
