Description

API 6A CRA Nickel Alloy Forging | UNS N07718 Inconel 718 Forged Components



The API 6A CRA / UNS N07718 Nickel Alloy Forging is a high-strength, corrosion-resistant component designed for extreme service conditions in oil, gas, and energy industries. Manufactured from Nickel Alloy 718 (UNS N07718), these forgings combine outstanding mechanical strength, fatigue resistance, and excellent stress-corrosion cracking resistance. Strictly produced to API 6A standards, they ensure reliable performance in demanding subsea and high-pressure environments.

Key Features

  • API 6A Compliance – Engineered and tested to meet the stringent requirements of the oil & gas industry.

  • Corrosion-Resistant Alloy (CRA) – Exceptional resistance against sulfide stress cracking, chloride attack, and sour gas environments.

  • Superior Mechanical Strength – Maintains tensile and yield strength even at elevated temperatures.

  • Excellent Fatigue Resistance – Long-lasting durability under cyclic loading and extreme pressure conditions.

  • Custom Forging Capability – Available in various forged shapes, including blocks, discs, shafts, and rings.
