SAE 4130 is a water-hardening alloy steel of low-to-intermediate hardenability. It retains good tensile, fatigue, and impact properties up to about 370 °C (700 °F); however, it has poor impact properties at cryogenic temperatures. This steel is not subject to temper embrittlement and can be nitrided. It usually is forged at 1100 to 1200 °C (2000 to 2200 °F); finishing temperature should never fall below 980 °C (1800 °F).

SAE 4130 Chemical Compositions

SAE 4130 Mechanical Properties

SAE 4130 structural steel is with high strength and toughness, high hardenability, in oil critical hardening 15 ~ 70 mm diameter; Hot strength of the steel is better under 500 ℃, which has the enough high temperature strength, but the strength owns a significant reduction in 550 ℃.

SAE 4130 Applications:
4130 alloy structural steel properties and applications: the steel has high strength, high toughness and good high temperature strength, good processability, cold bending plastic medium, high hardenability and good welding performance, generally used in the quenched and tempered condition.
