Inconel 625 Grade 2 Pipe is supplied in the solution annealed condition. The main difference between Grade 2 and Grade 1 is the annealing temperature. The minimum annealing temperature for Grade 1 is 1600F (871 degrees Celsius), while Grade 2 is now 2000F (1093 degrees Celsius). Schedule 40 (SCH 40) is suitable for medium pressure applications without sacrificing strength or flexibility. Contact us for more information and a free quote!
