Stainless Steel and Plates (SS 309)

Stainless Steel Grade 309 is a highly alloyed austenitic stainless steel engineered for high-temperature service. Containing high levels of chromium and nickel, SS 309 delivers superior heat resistance, exceptional oxidation resistance up to $1000^\circ\text{C}$ ($1832^\circ\text{F}$), and higher creep strength than standard SS 304. It maintains excellent toughness and mechanical integrity in severe thermal environments while offering strong resistance to marine and industrial atmospheres.
