A new grade of stainless steel, S17710, commonly referred to as 302PH, has been developed. This alloy is intended for use in either the solution annealed or precipitation hardened condition. In the solution annealed condition, S17710 is austenitic and is therefore proposed for addition under the "austenitic" grades section of Tables 1 and 2. S17710 can also be used in the PH condition following heat treatment at 470C for 1 hour. As A493 does not contain PH condition or heat treatment/property details, this alloy is ONLY being proposed for addition in A493 in the annealed condition, consistent with 5.2.2.
