AMS 6265 is a specification that applies to 9310 alloy steel (UNS G93100 ), a low-alloy, high-strength steel known for its excellent toughness, fatigue resistance, and wear properties.
9310 VAR AMS 6265 is a Chromium-Nickel-Molybdenum Alloy used as a Carburizing Grade for Aircraft Parts. Users can obtain high case hardness coupled with high core strength and toughness. High alloy content makes it suitable for use in relatively large cross-sections. Its combination of high alloy and low carbon content can achieve high core hardness with a narrow range between thicker and thinner part cross sections.
Under AMS 6265, 9310 alloy steel (UNS G93100 ) provides a combination of core toughness and surface hardness, achieved through heat treatment and carburizing processes. This makes it ideal for applications that require wear resistance without compromising the overall strength and toughness of the material.

Heat Treatment
| Type | Process |
|---|---|
| Annealing | Heat throughout to 1475° - 1575° F, then furnace cool |
| Normalizing | Heat throughout to 1650° - 1750° F, then air cool |
| Carburizing & Hardening | Carburize at 1650° - 1700° F, slow cool. To harden, oil quench from 1425-1545 F |
| Temper | At 250° - 350° F |
| Approx Case Hardness | 60 – 62 HRC |
| Approx Core Hardness | 331 – 363 BHN |
Typical Core Properties after Pseudo-Carburizing
| Heat Treatment | Tensile Strength | Yield Strength | Elongation in 2" | Reduction of Area | Core Hardness |
|---|---|---|---|---|---|
| Pseudo Carburized 1700° F for 8 hours. Oil quenched, Tempered at 300° F for 2 hours | 187 ksi | 155 ksi | 15% | 51% | 375 Bhn |
| Pseudo Carburized 1700° F for 8 hours. Slow cool to room temperature. Heat to 1425° F, oil quench. Tempered at 300° F for 2 hours | 155 ksi | 130 ksi | 15.5% | 52% | 331 Bhn |
| Pseudo Carburized 1700° F for 8 hours. Slow cool to room temperature. Heat to 1525° F, oil quench. Tempered at 300° F for 2 hours | 175 ksi | 155 ksi | 16% | 53% | 363 Bhn |
Pseudo Carburized: Heat Treat with same process as for Carburizing, but without the presence of Carburizing Gas Furnace Atmosphere.
Tempering
