How to improve toughness of a573 grade 58 carbon-manganese-silicon steel grade

Our company's a573 grade 58 carbon-manganese-silicon steel grade power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the a573 grade 58 carbon-manganese-silicon steel grade utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

Bridge steel plates are steel plates specially used to build railway or highway bridges. It is required to have high strength, toughness and bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The steel a573 grade 58 carbon-manganese-silicon steel grade for tie-welding bridges should also have good welding performance and low notch sensitivity。

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This a573 grade 58 carbon-manganese-silicon steel grade alloy steel a573 grade 58 carbon-manganese-silicon steel grade still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

Alloying elements can strengthen the properties of structural steels. a573 grade 58 carbon-manganese-silicon steel grade, Alloy structural steel has suitable hardenability. After proper metal heat treatment, the microstructure is uniform sorbite, bainite or very fine pearlite. Therefore, alloy structural steel has higher tensile strength and yield ratio (generally about 0.85), higher toughness and fatigue strength, and lower ductile brittle transition temperature. Alloy structural steel can be used to manufacture machine parts with larger section size.
