Super alloys or high performance alloys are of three types that include iron-based, cobalt-based and nickel-based alloys. These alloys are of different shapes and they possess good oxidation and creep resistance. Super alloys can function under high mechanical stress and high temperatures and also in places that require high surface stability. Super alloys can be strengthened by precipitation hardening, solid-solution hardening and work hardening methods.

S31500/3RE60 the mechanical properties of the report, the report provides detailed performance analysis and application.
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
3RE60 is an excellent material for use in chloride-bearing environments where pitting and stress corrosion cracking are potential problems. In such environments, 3RE60 is far superior to the standard austenitic steels. The material is therefore particularly well suited for use in heat exchangers that work with cooling water with moderate chloride contents.
Typical application examples are found in oil refineries, chemical and petrochemical plants and within the pulp industry.
The high strength and hardness of 3RE60 make the material an attractive alternative to the austenitic steels in structures that are subjected to heavy loads or wear.
