INCONEL alloy 718SPF is a specifically "tailored" version of INCONEL alloy 718, designed for the superplastic forming process. The alloy is optimized for the process by rigorous control of composition, melt practice and rolling conditions.

INCONEL alloy 718SPF was developed to meet the need for a nickel-base alloy suitable for manufacture into complex shaped components subject to a combination of high temperature, high temperature corrosion and high stress. INCONEL alloy 718SPF meets all the mechanical property requirements of AMS 5596G, as annealed plus aged, as well as all requirements of AMS 5950, which is specific to INCONEL alloy 718SPF.

Inconel 740 Tubing hardened nickel-based alloys and cold-worked solid nickel-based alloys offer many advantages such as high strength, toughness, low magnetic permeability and excellent corrosion resistance. Inconel 740 Tubing has proven to be a valuable and versatile material that is able to solve a wide variety of design and application problems. Inconel 740 Tubing has the ability to resist low temperature aggressive corrosion environments, as well as hostile high temperature environments. The excellent weldability of the alloy, and its ability to be joined very successfully to other alloys with different compositions.

Inconel 740 Tubing & other nickel based alloys from these ranges are ideal for cost-effective manufacture of pumps, valves and process control equipment in oil and gas extraction.

INCONEL alloy 740 is a precipitation-hardenable nickel-chromium-cobalt superalloy for high-temperature service in the automotive and power industries. The alloy is age-hardenable by the precipitation of a gamma prime second phase. Potential applications include advanced power production boiler tubes and diesel engine exhaust valves.
