Martensitic Stainless Steel Aermet 100 High Strength Mechanical AMS6532 K92580

Martensitic Steel Alloy A-100 High Strength Excellent Mechanical Performance

A-100 (AerMet 100) is an ultra-high strength type of martensitic steel alloy, It has a very hard form of steel crystalline structurewas and developed in response to a need for a stronger and tougher material with superior fracture toughness and ductility. The minimum tensile strength of the alloy is 280 ksi (1930 MPa).

Due to the alloy is not a corrosion-resistant alloy, the sealing must be performed if used in a wet environment. Excellent hardness, tensile strength, and ductility make the alloy a candidate for various applications, including landing gear, armor, fasteners, actuators, ordnance, jet aircraft, engine shafts, drive axles, and structural tubes. AerMet 100 high-strength steel can be used in operating condition up to 427 °C (800 °F).

Parameters

• Density: 7.9g/cm3(0.285lb/in3)
• Elastic modulus: 28.2 * 103KSI
• Resresistivity: 259.0 ohm-cir-mil / ft (70.0 ° F)

Advantages

• High hardness and strength
• Excellent mechanical performance
• Safety belts and strength
• Excellent ductility and toughness
• High fracture toughness
• Excellent fatigue and stress corrosion cracking resistance
• High fatigue strength

Decarburization

Like other carbon bearing high strength alloys, AerMet 100 alloy is subject to decarburization during hardening. Heat treatment should take place in a neutral atmosphere furnace, salt bath or vacuum. Decarburization should be determined by comparing the surface and internal hardness of a small test cube for proper response. Metallographic determination of decarburization is not recommended for this alloy.

Normalizing

AerMet 100 alloy can be normalized by heating to 1650° F (899° C) holding for one hour and air cooling to room temperature. Optimum softening for machining is obtained by following the 1650° F (899° C) normalize with a 16 hour 1250° F (677° C) overage anneal.

Annealing

AerMet 100 alloy is softened by using a 1250° F (677° C) overage anneal for 16 hours. The optimum annealed hardness of 40 HRC maximum is obtained following this anneal.

Solution Treatment

The solution treatment temperature range is 1625° F+/-25° F (885° C +/-14° C) for 1 hour. The solution treatment temperature must be monitored by a thermocouple attached to the load.
