Product Details

4130 Chromium-Molybdenum Alloy Tubing has a suitable hardenability, after a suitable metal heat treatment, the microstructure becomes a uniform arithmetic, bainite or a very fine pearlite, So it has a higher tensile strength and box strength ratio , higher toughness and fatigue strength,  lower toughness-brittleness transition temperature, which can be used to manufacture machine parts with larger size.

4130 Chromium-Molybdenum Alloy Tubing is usually used in the quenched and tempered state. When the carbon content is the lower limit, the steel can also be used as a carburizing steel that requires a higher core strength. In the medium-sized machinery industry, it is mainly used to manufacture quenched and tempered parts with large cross-sections and working under high stress conditions, such as shafts, spindles, and high-load control wheels, bolts, double-headed screws, gears, etc.
