CF10SMnN Stainless Steel: High Wear Resistance
Description
CF10SMnN stainless steel is recognized for its excellent wear resistance, even at elevated temperatures. The addition of 4% silicon and 8% manganese reduces wear, galling, and abrasion. This steel grade is commonly used for fasteners and pins requiring both strength and wear resistance. It retains good mechanical properties up to 1800°F and offers oxidation resistance comparable to 309 stainless steel. Its general corrosion resistance is between that of 304 and 316 stainless steels.
