UNS S21800 Forging Bar Nitronic 60 Stainless Steel Forged Round Bar for Valve Components

UNS S21800 Forging Bar Nitronic 60 Stainless Steel Forged Round Bar for Valve Components

UNS S21800, also known as Nitronic 60, is a nitrogen-strengthened austenitic stainless steel forging bar engineered for applications demanding exceptional galling resistance, high strength and outstanding corrosion resistance. Our forged round bars are produced through precise open die and closed die forging processes, followed by solution annealing to deliver 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.
• Excellent Corrosion Resistance: Comparable to 316 stainless steel in most corrosive media, with enhanced resistance to chloride stress corrosion cracking.
• Wide Size Range: Diameters from 20mm to 500mm, custom lengths available upon request.
• Full Traceability: Mill test certificates, material inspection reports and third-party testing available.

Applications

UNS S21800 forged bars are widely used for valve stems and seats, pump shafts, fasteners, bearings, conveyor components and other wear-critical parts in chemical processing, marine, pulp & paper and food processing industries.
