What is ASTM B443 Alloy 625 Gr.2 (UNS N06625 / DIN 2.4856)?

Commonly known as Inconel 625, Alloy 625 Gr.2 (UNS N06625, DIN 2.4856) is a non-magnetic, solid-solution strengthened nickel-chromium-molybdenum-niobium superalloy. The unique combination of molybdenum and niobium elements in its nickel-chromium matrix grants the alloy exceptional mechanical strength, outstanding toughness, superior high-temperature oxidation resistance, and full-spectrum corrosion resistance. This premium nickel-based superalloy maintains stable structural integrity across extreme temperature ranges, from cryogenic conditions up to 1093°C (2000°F), making it indispensable for harsh high-temperature, high-pressure, and corrosive industrial working environments.

The internationally recognized ASTM B443 specification defines two professional grades of Alloy 625, tailored for distinct temperature and stress application scenarios. The grade difference mainly lies in heat treatment processes and high-temperature resistance performance, meeting diverse industrial standard requirements:

Alloy 625 Gr.1 (Annealed Condition): Designed for conventional industrial applications with continuous service temperatures below 593°C (1100°F). It delivers stable general corrosion resistance and reliable structural performance for medium and low-temperature working conditions.

Alloy 625 Gr.2 (Solution Annealed Condition): Specially engineered for critical high-temperature environments exceeding 593°C (1100°F), requiring excellent creep resistance and stress rupture resistance. The professional solution annealing process heats the UNS N06625 alloy plate to 1093°C (2000°F) followed by rapid quenching, which optimizes internal metallographic structure, significantly enhances high-temperature creep strength and long-term structural durability. It is the preferred material for high-temperature pressure vessels, thermal cycle components, and mission-critical industrial equipment.

Property	Value / Description
