Description:
In addition to iron and carbon, other alloy elements are added to steel, which is called alloy steel. The main alloy elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth, etc. According to the different added elements and combine with proper processing technology, the special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance and non magnetism can be obtained by alloy steel plate.
Application:Alloy structural steel is used to make important engineering structures and machine parts. Alloy quenched and tempered steel is widely used in manufacturing various important parts of automobiles, tractors, machine tools and other machines, such as gears, shafts, connecting rods, bolts, etc.

Manufacturing Technique
Cuttinglarge steel plates as your requirements to make the surface of the plate bright by miling and grinding, also can make holes and make angle degrees,and can weld by your drawing.
For the thickness under 30mm, cutting by laser; For thickness over 30mm, mainly OXY-cut, flame cutting.
For the thickness 200mm steel plate, because during the flame cutting, the temperature is very high, so the cutting parts steel plate might be broken at the angle part, then our workers will repair the angles to be good condition.
