Application of 30CrMnSiA steel, A514 grade C alloy steel plate:30CrMnSiA steel is generally used after quenching and tempering. 30CrMnSiA steel is mainly used to manufacture various important parts with high load and high speed, such as gears, shafts, clutch friction plates, sprocket wheels, grinding wheel shafts, shaft sleeves, bolts, nuts, etc. 30CrMnSiA steel is also used for manufacturing wear-resistant parts with low working temperature and variable load welding components, such as blades, valve plates and non corrosive pipes and pipes of high-pressure blowers.
Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of A514 grade C alloy steel plate, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).
Alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel. Welding and forming of this steel plate A514 grade C alloy steel plate should be avoided. It is best utilized wherever high resistance to fatigue and or impact is necessary. We can supply ASTM, JIS, DIN and GB various standards alloy steel grades.
After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
