Steelmaking
The main alloy steel elements have silicon, manganese, chromium, nickel, tungsten, molybdenum, vanadium, titanium, niobium and zirconium, cobalt, aluminum, copper, boron, rare earth, etc. Which vanadium, titanium, niobium and zirconium, etc in steel is strong carbide form elements, as long as there is enough carbon, in the right conditions, to shape their own carbide, when lack of carbon or in high temperature conditions, the one with atomic state into the crystallology; Mn, chromium, tungsten, molybdenum carbide form elements for, some of the atoms in the state to enter the crystallology, another part of form replacement type alloy cementite; Aluminum, copper, nickel, cobalt, silicon carbide is not formed elements, general with atomic state exists in the crystallology. Free cutting steel: in steel join a certain number of one or more than one type of sulphur, phosphorus, lead, calcium, selenium, tellurium and cutting elements to improve its cutting sex of alloy. Also called the automatic machine processing steel, hereinafter referred to as automatic steel. This kind of steel can use high cutting speed and large cutting depth cutting processing. Because of the free cutting steel join element, make steel cutting resistance decreased, and cutting element characteristics of itself and by the formation of the compounds for lubrication cutting tool role, brittle flocks, reducing wear and thus reduce the workpiece surface roughness and the tool life and improve the production efficiency. Spring steel is mainly have good elasticity, and because it is in the dynamic loading environment conditions of the job, so to make the material of spring the main should have high yield strength; Under heavy load in does not cause the plastic deformation; Should have high fatigue strength, load under the action of repeated in with long service life; And have enough toughness and plastic, in case in the impact a role brittle fracture.
