Inconel 718 Plates
Description

Inconel 718 plate is a precipitation-hardenable nickel-chromium alloy known for its exceptional strength, corrosion resistance, and outstanding high-temperature performance. The alloy maintains excellent tensile, creep, and rupture strength up to about 700°C (1290°F), making it one of the most widely used superalloys in aerospace, power generation, and chemical processing industries.

Due to its balanced composition of nickel, chromium, molybdenum, and niobium, Inconel 718 offers superior resistance to oxidation and pitting in both oxidizing and reducing environments. It is easily fabricated and weldable compared to many other nickel-based superalloys, while still providing remarkable fatigue and stress corrosion cracking resistance.

We offer Inconel 718 plates in various thicknesses, tempers, and specifications, cut to customer requirements, ensuring reliable performance in demanding high-temperature and corrosive service conditions.

Prices

Specification (Thickness / Width)	China (USD/kg)	India (USD/kg)	Europe (USD/kg)	USA (USD/kg)	Remarks
Thin Plates ≤ 6 mm	55 – 70	60 – 75	75 – 95	80 – 100	Cold rolled or hot rolled; used in aerospace, chemical, and marine applications. Surface finish and certification affect price.
Medium Plates 6 – 20 mm	50 – 65	55 – 70	70 – 90	75 – 95	Hot rolled; commonly used for structural components. Width, temper, and certification impact pricing.
Thick Plates ≥ 20 mm	48 – 60	53 – 65	68 – 90	73 – 95	Heavy plates for aerospace, turbines, and chemical reactors. Larger plates reduce unit cost but increase total cost.
Small Batch (< 500 kg) Surcharge	+10% ~ +25%	+10% ~ +25%	+15% ~ +40%	+15% ~ +45%	Prototype, small quantity, or urgent delivery increases cost; aerospace-grade certifications add extra premium.
