Alloy steel and carbon steel 2017-09-04 10:34:18

The difference between alloy steel and carbon steel: 1. The definition of steel: steel can be divided into carbon steel and alloy steel according to its carbon content and the content of alloy composition. Is a steel alloy of iron and carbon or carbon in the crystal in the iron solid solution. The steel refers to the steel in addition to containing silicon and manganese as alloying elements and deoxidizing elements, also contain other alloying elements (such as chromium, nickel and molybdenum, vanadium, titanium, copper, tungsten, cobalt, aluminum, niobium, zirconium and other elements etc.), and some also contain some nonmetallic elements (such as boron and nitrogen) steel. In accordance with the element content in steel alloys ", can be divided into low-alloy steel, medium alloy steel and high alloy steel. Steel is a kind of steel in addition to containing certain amount in order to join the deoxidation silicon (generally not more than 0.40%) and manganese (generally not more than 0.80%, higher to 1.20%) and other alloying elements, does not contain other alloying elements (except for the residual elements of steel). According to the content of the concave and convex and Nianye can be divided into low carbon steel (carbon content is generally less than 0.25%); medium carbon steel (carbon content is generally between 0.25%-0.60%); high carbon steel (carbon content of a show of 0.60%). But there is no harsh border between them. Two, alloy steel definition: contains other alloy elements steel is alloy steel. The total content of alloy elements is high alloy steel can reach 10~28%. Alloy steel is the addition of iron and five elements of nature in steel, but also the addition of additional alloy elements to alter or improve certain characteristics of steel, such as CrNiMnMoWVB. In addition to iron and carbon, alloy steel also involves some other metals that change the function of the material. The action of chromium is to make the steel has erosion resistance, the action of nickel is to reduce the austenitizing temperature of stainless steel. Three carbon steel definition: carbon steel does not contain other alloy elements; carbon steel is also carbon containing less than 1.35% of the steel. Carbon steel, which in addition to iron, carbon materials generally only silicon manganese and phosphorus sulfur in these five big natural elements, and then did not add other alloying elements. Four. The difference between alloy steel and carbon steel: carbon steel does not contain useful alloy elements. It is an alloy with iron, carbon and manganese as the primary elements. Mechanical performance is usually inferior to alloy steel. Moreover, the price of carbon steel is much lower than that of alloy seamless steel tube. From the above 2 points, the Suzhou alloy steel supplier believes that the function of alloy steel exceeds that of carbon steel, which is the biggest difference.
