UNS S21800 Forging Sleeve Nitronic 60 Forged Cylinder Sleeve

UNS S21800, also known as Nitronic 60, is a nitrogen-strengthened austenitic stainless steel forged sleeve engineered for applications demanding exceptional galling resistance, high strength and outstanding wear performance. This forged cylinder sleeve is precisely manufactured to 300mm outer diameter, 200mm inner diameter and 600mm length through open die and closed die forging processes, followed by solution annealing for a uniform fine-grained microstructure.

Key Features

• Superior Galling Resistance: Outperforms conventional 304 and 316 stainless steel in metal-to-metal wear and galling applications.
• High Strength: Nitrogen-strengthened matrix provides higher yield strength than standard austenitic grades at room and elevated temperatures.
• Precision Dimensions: 300mm OD x 200mm ID x 600mm length, machined to tight tolerances upon request.
• Excellent Corrosion Resistance: Comparable to 316 stainless steel in most corrosive media, with enhanced resistance to chloride stress corrosion cracking.
• Full Traceability: Mill test certificates, material inspection reports and third-party testing available.

Applications

UNS S21800 forged sleeves are widely used for valve components, pump shafts, wear sleeves, bearing housings and other wear-critical parts in chemical processing, marine, pulp & paper and food processing industries.
