Grade SDM
Sink, dairy & moderate-corrosion grade with balanced Cr-Mn-Ni chemistry.
Material Overview
Cr-Mn Austenitic (Jindal)
SDM (Sink-Dairy-Moderate) is positioned for components that face occasional moisture and mild chemical exposure — particularly in kitchens, dairies, and small-format food processing. It bridges the cost gap between Cr-Mn series and 304.
Equivalent / Comparable: Between J4 and 304
