The wide range of superalloys and their diverse properties mean that material selection depends on the specific requirements of each project. Arya Steel Mehregan takes a specialized sourcing approach, assessing each material request individually to identify options that match the customer's technical requirements.
Superalloys are a group of advanced engineering materials designed to perform under demanding service conditions. Depending on their composition and microstructure, these alloys can retain mechanical strength, creep resistance, thermal stability and resistance to oxidation or corrosion in specific environments.
In many industrial applications, selecting an alloy cannot be based solely on its grade designation or the content of a single element. Service temperature, environment, mechanical stress, thermal cycles, fabrication methods and applicable standards must all be considered together.
Retention of mechanical properties under demanding thermal conditions
Performance suited to specific chemical environments
Resistance to gradual deformation under sustained load
Retention of structure and properties during long-term service
Superalloys and heat-resistant alloys are classified into different groups according to their base elements and alloy structures. The following are three important families of these materials.
Depending on their alloying elements, this family can offer a combination of properties such as corrosion resistance, oxidation resistance, high-temperature strength and stability under demanding service conditions.
Cobalt-base alloys are used in certain high-temperature and demanding service environments, where high-temperature strength, oxidation resistance and property stability are important.
This family includes heat-resistant alloys with properties such as creep strength, structural stability and resistance to oxidation and certain corrosive environments.
Some well-known alloys used in various industries are introduced below. This list is intended for general reference only and does not imply confirmed stock availability or guaranteed sourcing of every material.
A high-strength alloy offering excellent resistance to a wide range of corrosive environments, including pitting and crevice corrosion.
A precipitation-hardening alloy with high mechanical strength and the ability to retain its properties at elevated temperatures.

This page is not an exhaustive list of all superalloys and special alloys. Other materials, such as Alloy 617, X-750, Waspaloy, C-22 and other specialized alloy families, may also be considered depending on the application.
Due to the wide variety of superalloys, differences in chemical compositions, standards, product forms and specialized applications, it is not possible to provide one fixed list of specifications and prices for all materials.
For this reason, each customer request is assessed individually after submission. The review covers technical specifications, service conditions, required documentation and sourcing feasibility.
Submit an Assessment Request →The material name, grade, standard and initial order specifications are collected.
Chemical composition, mechanical properties, service conditions and intended application are reviewed.
Product form, dimensions, thickness, required quantity and sourcing possibilities are evaluated.
The assessment results and information about potentially available options are communicated to the customer.
The more complete the initial request, the more accurately technical requirements and potential sourcing options can be evaluated.
Trade name, grade designation or UNS number, if available
Sheet, plate, strip, bar or other required product form
Applicable technical standard and required analysis certificate or MTC
Operating temperature, corrosive environment and mechanical conditions
Required thickness, dimensions, number of pieces or total weight
