Difference between SA182-304 and SA479-304

[radd02]

Are these two alloys interchangeable, or is there an annealing process that makes interchange impossible?

SA-479 covers bars and shapes. SA 182 covers forgings.

Some product forms in some sizes may be certified to both. You really need to read each spec as to heat treatment, etc.

SA-479 references heat treatment per SA-484, which requires 304 to be in the solution annealed condition.
