Work Item
ASTM WK91200
Revision of A240/A240M-24 Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications
Rationale
Studies have shown that 8-10 grains through thickness are required for adequate ductility of polycrystalline sheets. Since grain size control is difficult, an adequate margin must be applied above ten times the minimum specified grain diameter.
