Questions about alloy steel casting service
Low-alloy steel refers to alloy steel with a total amount of alloying elements less than 5%. Low-alloy steel has been widely used in the manufacture of construction machinery, ships, bridges, high-rise buildings, boilers and pressure vessels, electric power, and various vehicles. High-alloy steel refers to alloy steel with more than 10% alloying elements in the steel. High-alloy steel includes high-quality alloy steel and special alloy steel; according to characteristics and uses, it is divided into alloy structural steel, stainless steel, acid-resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel, rolling bearing steel, alloy spring steel and special performance steel.
Chromium, molybdenum, vanadium, manganese, nickel
Low alloy steels have less than 8% total alloying elements in the composition, these steels have better hardness and resistance to wear over carbon steel but tend to have less tensile strength. The high alloy steels have more than 8% alloying elements and have better properties than those of the low alloying steels.
1: High strength, good plasticity and toughness. Due to the effect of alloying elements, its strength is 25%-50% higher than ordinary carbon steel, its elongation is 15%–23%, and its impact toughness at room temperature is higher than 60J/cm^2.
2: Good weldability. Because of the low carbon content and low alloying element content, its plasticity is good, and the hardenability is low, it is not suitable for quenched structure or cracks to appear at the weld.
3: Good cold and hot pressure processing performance. Due to its good plasticity and low deformation resistance, it is not easy to produce cracks after pressure processing.
4: Good corrosion resistance. It has higher corrosion resistance than carbon steel under various atmospheric conditions.
