What is AMS5662?
What is AMS5662?
AMS 5662 is a designation of Nickel Inconel 718, itself a nickel-chromium alloy with high strength, corrosion and oxidation resistance, and excellent tensile and impact strength at cryogenic temperatures. Nickel Inconel 718 AMS 5662 can be age-hardened directly, without stress relief.
What is B637 ASTM?
ASTM B637 Round Bar is a precipitation hardening nickel super alloy that combines superior corrosion resistance and strength with high weldability.

How can you tell the difference between Inconel and stainless steel?
Inconel, a product of Special Metals Corp., has a nickel, chromium and molybdenum composition. Inconel is resistant to corrosion and pitting and comes in several different alloys. Stainless steel is composed of carbon, manganese, phosphorus, sulfur, silicone, chromium and nickel.
What does AMS 5662 mean?
Alloy 718 is a high nickel alloy that can be heat treated for higher strength. Rolled Alloys stocks annealed 718 (AMS 5662) and aged 718 (API 6A). The annealed condition (AMS 5662) is commonly sold for general use in the Aerospace and Oil & Gas industries, and can be heat treated to meet various other conditions.
Why choose AMS 5662/5663 SSS Super Alloys?
Alloy 718 – AMS 5662/5663 SSS Super Alloys specialise in the supply of Alloy 718 for aerospace application. Alloy 718 is a high strength nickel-base alloy initially developed for the aerospace industry and is used in applications requiring high strength to approximately 1400°F (760°C) and oxidation resistance to approximately 1800°F (982°C).
What is the difference between ams5663 and astm-5663?
The ageing cycle of AMS5663 does not have that leeway and all sizes are treated at the same ageing times and temperatures. The next difference comes in the expected grain size. Both material standards allow bars and flash welded rings under 58 cm² cross sectional area to have a grain size of ASTM 5 or finer.
How long does it take for AMS 5662 to age?
AMS 5662: Solution annealed between 941-1010°C followed by rapid cooling AMS 5663: As above plus precipitation hardened at 718°C for 8 hours, furnace cooled to 621°C and hold for total ageing time of 18 hours
