Nitronic 60 (UNS S21800) stainless steel for action
|
|
Nitronic 60 (UNS S21800) Description
The Nitronic 60 is known for its excellent wear resistance, even at high temperatures. Adding 4% silicon and 8% manganese inhibits wear, wear and tear. It is commonly used for a variety of fasteners and pins that require strength and wear resistance. It maintains good strength at temperatures up to 1800°F and has similar yang resistance to 309 stainless steel. General corrosion resistance between 304 and 316 stainless steel.
