Alloy X-750 High-Temperature Corrosion-Resistant Superalloy

Quality Assurance

We strictly adhere to ASTM B637,AMS 5598, AMS 5542,AMS 5582, AMS 5667 and AMS 5670 standards. Each batch undergoes chemical composition analysis, tensile testing, and hardness verification, with complete inspection reports provided to ensure full material traceability. Our AS 9120B and ISO 9001:2015 certifications guarantee supply chain quality management. 

Delivery Capability

We maintain stock for standard sizes across multiple forms (bar, sheet, wire, coil) and support custom length, diameter, and tolerance requirements, with a typical lead time of 4-6 weeks.

Technical Support

Our engineering team provides material selection guidance, heat treatment recommendations, and processing consultation to help you optimize product performance and cost.

Workability

The furnace temperature should be 2100°F (1149°C)-for optimal starting temperatures of 1950/2000°F. For service below 1100°F (593°C), higher strength can be obtained by combining some cold work with heat treatment because the effects are additive.

Machinabiliy

Alloy X-750 work hardens quickly and is more difficult to machine than most standard ferritic and martensitic alloys. The alloy is most easily machined in the stress-equalized condition. Because specific cutting forces are high, the machine tools used must have ample power and the cutting speed should be slow. The tools must have smooth finishes, be sharp, and be very rigid. To avoid work hardening , a continuous, smooth cutting action should be maintained; thus, the machines must have a minimum of backlash and the tool and workpiece must be rigidly supported. If at all possible, avoid very small cuts and feeds.

Welding

Alloy X-750 should be welded in the stress-equalized condition, 1625°F (885°C) heat treatment, and solution treated and age hardened after welding has been completed. If this is not practical, the alloy should be welded in the solution-treated condition and age hardened after welding with or without the inclusion of a short-period stress-relieving treatment at 1625°F. Weld joints, because of softening of the alloy within the heat-affected zone, should be located where lower creep properties are required.
