Deformed steel bar/In summary, the national standard GB/T13304 "steel classification" according to the chemical composition of the steel is divided into three categories: non-alloy steel, low-alloy and alloy steels. The international and European standards and foreign standards by some of the chemical composition of the steel into two categories: non-alloy and alloy steels, low alloy high strength steel alloy is only in a small class. There are many American ASTM standard low-alloy steel standard, most high strength low alloy steel standard.Deformed steel bar price
 

Of low-alloy steel grades have been a complete series and standard series. Grades series to manganese-based, some micro alloying elements molybdenum, niobium, vanadium, copper, nitrogen and rare earth. Wherein the mass production is 16Mn. If you follow some standard country or organization to classify steel, then some of our low-alloy steel should be classified as non-alloy steel, basically. American ASTM standard low-alloy steel is the same, except for some chrome, nickel content of high grades, many brands also classified as non-alloy steel. American ASTM standards as well as "carbon-manganese steel," as a kind of carbon steel, most of them with low-alloy steel approximation of manganese. Chemical
