Steel is greater than 0.025%, less than 2.11% of the carbon content of iron alloy carbon. Will the iron ore mining in blast furnace is then get pig iron smelting, pig iron smelting process and according to different purposes can be divided into steelmaking pig iron and casting pig iron.Steelmaking cast iron is a kind of carbon content > 2% of iron alloy carbon, but also with a small amount of silicon, manganese, sulfur and phosphorus silicon and manganese elements, which is beneficial elements, according to a certain proportion of existing steel can significantly enhance the strength of the material.Hardness and corrosion resistance and wear resistance, sulfur and phosphorus are harmful, will cause the hot steel respectively brittle and cold brittleness, reduce the material performance.The steelmaking with pig iron into LianGangLu according to a certain proportion of melting, will get the liquid steel casting forming, cooling namely after ingot casting, or get into various profiles for rolling, in order to get the different performance of steel, will be in smelting process to join chrome... Tungsten molybdenum nickel. Vanadium and other trace elements, and the chemical composition of the different characteristics to steel.The "chrome" can increase steel corrosion resistance, usually the international containing cr amount more than 13% of steel called stainless steel.Nickel can increase the strength of steel and toughness, molybdenum can prevent steel brittle, tungsten steel can increase the wear resistance sex, don't see tungsten hardness is low, only about 40 s, but their resistance to wear ability is very high, vanadium can increase the steel resistance to wear sex and ductility.Low carbon steel-carbon content is less than 0.25% carbon structural steel-mostly in the carbon content below 0.7%.
Medium-carbon steel-carbon content in 0.25 ~ 0.6% carbon tool-carbon content in general 0.65 ~ 1.35%.
High carbon steel-carbon content is more than 0.60%.
Stainless steel-carbon content in general 0.45 0.7%, more than 13% of containing cr.
The rolling bearing stainless steel, carbon content is in commonly 1%, including chromium quantity is more than 13%.
High speed steel-also called feng steel, carbon content in 0.7 ~ 1.65%, general with tungsten 5.5 ~ 19% and 600 degrees Celsius, hardness work can keep in HRC60 above.

GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
Bulb flat steel for shipbuilding
The bulb flat steel is a kind of medium section material which is mainly used in the field of shipbuilding and bridge building, and the shipbuilding bulb flat steel is an auxiliary medium section material for shipbuilding.
The steel for shipbuilding and oil platform---FH40, is the high tensile strength steel.The shipbuilding steel FH40 is the Hull structural steel.We can provide FH40 shipbuilding steel plate price.
