Carbon Steel

Carbon steels are a type of instrumental staley.Oni widely used for the manufacture of metal-working tools, various accessories and parts engineering (shafts, gears, bushings, etc.), instrument making, shipbuilding and stankostroeniya.Svoystva carbon steels determined by the amount of carbon content in them and depending on this carbon tool steels are divided into grades. High-quality carbon steel (grade A) have fewer contaminants and less prone to cracking during quenching and shlifovke.Oni less dye and therefore preferable in the production of more complex form tools in steel and detaley.Uvelichenie carbon content increases its hardness, but at the same time and were not hrupkost.Uglerodistye have red hardness, ie can not retain the hardness when heated to 300-400 degrees Celsius. The original structure of carbon steels to provide them with good workability and structure meets the conditions zakalivaemost.Etim fine pearlite with uniformly distributed grains of excess tsementita.V depending on the carbon content of carbon steels have rzlichnoe application. For the manufacture of percussion instruments, such as: chisels, axes, stomestki, brand, sledge hammers and other uses carbon steels U7 and U7A. Steel U10, U10G, U10A used for tools and parts with high strength and toughness of some intended for the unstressed work wear: taps, dies, drill bits for wood, tapered and shaped gauges, bushings and clamps konduktornyh. Steel U12 and U12A – for instruments with very high hardness in the unstressed work: countersinks, reamers, taps, surgical tools, metal saws and other tools used in metalworking, woodworking, etc. Steel U13A and V13 – for high hard tool with thin blades: engraving tool, blades, scrapers, wire-drawing tool.
