Nickel Alloys Alloy 718 Industrial Valves Overview
Zeon Exports supplies Nickel Alloy 718 (Inconel, UNS N07718) industrial valves – ball, gate, globe and check types – a precipitation-hardening nickel-chromium superalloy with exceptionally high strength from cryogenic temperatures up to 704°C.
Nickel Alloy 718 (Inconel) Industrial Valves control and isolate flow in the most demanding high-pressure, high-temperature and sour-service process lines where standard valve alloys lack sufficient strength. Its niobium-driven age hardening gives exceptional strength and creep-rupture properties from cryogenic temperatures up to roughly 704°C without sacrificing weldability.
- Age-hardened via niobium, aluminum and titanium for very high strength
- Tensile ≥1241 MPa, yield ≥1034 MPa in the aged condition
- EN 10204 3.1 certified, export-ready worldwide

Corrosion Resistance of Nickel Alloys Alloy 718
Nickel Alloy 718 Industrial Valves combine corrosion resistance with the highest strength of the common nickel superalloys.
- Pitting and crevice resistance: chromium and molybdenum give strong resistance to pitting and crevice corrosion.
- Oxidation resistance: performs reliably in oxidizing atmospheres up to its service temperature ceiling.
- Sour-service resistance: API 6ACRA variants are qualified for NACE MR0175 sour oil & gas service.
Heat Resistance of Nickel Alloys Alloy 718
Nickel Alloy 718 valves retain their strength up to roughly 704°C (1,300°F) and remain ductile and tough down to cryogenic temperatures. Strength drops sharply above roughly 650°C as strengthening precipitates transform. Confirm exact service limits against the governing standard and application before specifying.
Key Properties of Nickel Alloys Alloy 718 Industrial Valves
Beyond corrosion and heat performance, Alloy 718 valves offer these additional properties.
- Highest strength of the common wrought nickel superalloys
- Excellent weldability with resistance to strain-age cracking
- Good creep-rupture strength at elevated temperatures
- Remains ductile and tough at cryogenic temperatures

Frequently Asked Questions About Nickel Alloys Alloy 718 Industrial Valves
Common questions about Nickel Alloy 718 (Inconel) Industrial Valves, answered below.
Q1: What is Nickel Alloy 718 (Inconel)?
Ans. Inconel 718 (UNS N07718) is a precipitation-hardening nickel-chromium superalloy strengthened by niobium, aluminum and titanium.
Q2: What standards do Inconel 718 valves meet?
Ans. Valves are manufactured per applicable ASTM forging/casting standards, certified to EN 10204 3.1 mill test certificates.
Q3: What is the maximum service temperature?
Ans. Inconel 718 retains its strength up to roughly 704°C (1,300°F); confirm the correct condition against your design code.
Q4: Is Inconel 718 magnetic?
Ans. Inconel 718 is essentially non-magnetic in the aged condition, being an austenitic nickel-based alloy.
