ASTM B444 GR.2 INCONEL 625 (NO6625) DIN 2.4856 NICKLE ALLOY SMLS PIPE
In ASTM B444， the specification specifically applies UNS N06852 and UNS N06219 for delivery in the solution-treated state. Regarding Inconel 625 (UNS N06625)， the specification outlines two states:
Grade 1 (Annealed): Grade 1 refers to the annealed state of Inconel 625. It is stronger and suitable for use at temperatures up to 1100°F (593°C). Grade 1 is typically the default delivery state for Inconel 625 and tubes. It is commonly used in applications where high corrosion resistance is required at moderately elevated temperatures.
Grade 2 (Solution Annealed): Grade 2 corresponds to the solution annealed state of Inconel 625. This state is recommended when the material is intended for use above 1100°F (593°C). Grade 2 helps to improve the creep and fatigue properties of the alloy， making it suitable for high-temperature applications. If you have the need for Inconel 625 and tubes to be used at higher temperatures， Grade 2 is the appropriate choice.
