Introduction

Nitronic 60 stainless steel provides a significantly lower cost alternative to fight wear and galling compared to cobalt and high nickel alloys.

Nitronic 60/ UNS S21800/ alloy 218 stainless steel round bar

• Nitronic 60/ UNS S21800/ alloy 218 stainless steel round bar overview:
  • Nitronic 60(S21800) is known for its excellent galling resistance, even at elevated temperatures
  • The additions of 4% silicone and 8% manganese inhibit wear, galling, and fretting
  • It is commonly used for various fasteners and pins that require strength and resistance to galling
  • It maintains decent strength up to temperatures of 1800°F and has oxidation resistance similar to that of 309 stainless steel
  • The general corrosion resistance is between that of 304 and 316 stainless steel
