Product Description
UNS S21800 Oxidation Resistance and Low Temperature Impact Resistance
Introduction
UNS S21800 stainless steel provides a significantly lower cost alternative to fight wear and galling compared to cobalt and high nickel alloys.
Chemical composition
| Element | Ni | Cr | Mn | Si | C | N | S | P | Fe |
| Weight(%) | 8.00~9.00 | 16.00~18.00 | 7.00~9.00 | 3.5~4.5 | ≤0.10 | 0.08~0.18 | 0.030 | 0.060 | Rem |
Characters
Nitronic 60’s uniform corrosion resistance exceeds SS304 in most media. Chloride pitting resistance is superior to SS316 and room temperature yield strength is twice of SS304 or SS316. Nitronic 60 offers excellent high temperature oxidation resistance and low temperature impact resistance.
Applications
Outstanding galling resistance at both room temperature and elevated temperatures makes Nitronic 60 Stainless Steel a valuable material for valve stems; seats and trim; fastening systems, including nuts and bolts; chain drive systems; pins, bushings and bearings; and pump components such as wear rings and lobes. Nitronic 60 is the most effective wear and galling resistant material for bridge pins and is used in hydroelectric dam wear applications. Cavitation erosion resistance of Nitronic 60 is superior to the austenitic stainless steels as well as duplex stainless steels making it highly successful for wear rings in vertical centrifugal pumps. The combination of Nitronic 60 and Nitronic 50 has replaced cobalt wear alloys in some cases. The use of Nitronic 60 weld overlay on most other stainless steels and certain carbon steels develops sound deposits with wear galling resistant properties about equal to an all weld deposit.
