 PRODUCT SPECIFICATIONS

40CrMnMo Steel Rod is a high-performance alloy structural steel material, which is widely used in the field of industrial manufacturing for its excellent comprehensive mechanical properties and heat treatment characteristics. The material is composed of carbon, chromium, manganese and molybdenum as the main alloying elements, and a unique microstructure is formed through precise proportioning. Among them, chromium significantly improves the surface hardness and corrosion resistance, manganese enhances the overall strength and wear resistance of the material, and the addition of molybdenum effectively improves the creep resistance and hardenability under high temperature environment, ensuring that large-section workpieces can still maintain uniform mechanical properties after quenching and tempering. After the quenching and high-temperature tempering quenching and tempering process, the steel rod can obtain an ideal match of strength and toughness, and its tensile strength can reach more than 900MPa, while maintaining good plasticity indicators. It is particularly suitable for manufacturing key load-bearing components such as precision gears, heavy-duty transmission shafts, hydraulic struts, etc. that bear complex alternating loads. In terms of processing performance, the material exhibits good machinability and moderate welding characteristics, and can be further improved by strengthening treatments such as surface carburizing and nitriding. The service life under specific working conditions. Its stable chemical composition control and strict production process management ensure that each batch of products meets the requirements of GB/T3077 standards and meets the stringent demands for high-strength and high-reliability structural parts in the fields of engineering machinery, mining equipment, automobile manufacturing and mold industry.

 FEATURES OF 42CRMNMO ALLOY STEEL BAR

The product advantage of 40CrMnMo Steel BAR lies in its excellent comprehensive performance: through the synergistic effect of carbon, chromium, manganese and molybdenum, it has high strength (tensile strength ≥900MPa), high toughness and excellent wear resistance, especially under high load and complex stress environment; after quenching and tempering treatment, the microstructure is uniform, and large-section workpieces can still maintain stable mechanical properties to meet the needs of high-temperature creep resistance; high processing flexibility, support cutting, welding and surface strengthening processes (such as carburizing/nitriding), can be targeted to extend the life of key components; strictly follow the GB/T3077 standard production, chemical composition and process control are precise, meet the engineering machinery, automobile manufacturing and other fields for high-strength, high-reliability structural parts of the stringent requirements, is the ideal material for heavy-duty transmission, precision gears and other core components.
