NITRONIC 60 -Weldability
Back To Weldability Alloys
NITRONIC 60 Stainless Steel gives a combination of corrosion resistance and strength not found in any other commercial material available in its price range. This austenitic stainless steel has corrosion resistance greater than that provided by Types 316 and 316L, plus approximately doubles the yield strength at room temperature. Likewise,NITRONIC 60 Stainless Steel has good mechanical properties at both high and sub-zero temperatures. Furthermore, unlike various austenitic stainless steels, NITRONIC 60 does not become magnetic when cold worked.
This working does not improve the anti-galling properties, as are ordinary for carbon steels and some stainless steels. The advantage of the cold or hot work put into the material is included strength and hardness, and the wear resistance does not decrease noticeably. Chromium and Nickel additions give it similar corrosion to 304 and 316 stainless steels, while having around double the yield strength. The high mechanical strength in annealed parts grants utilization of decreased cross sections for weight and cost reductions using thinner stock.
Applications
- Automotive valves - can withstand gas temperatures of upto 1500°F for a minimum of 50,000 miles.
- Fastener galling - capable of frequent assembly and disassembly, allowing more use of the fastener before the threads are torn up, also helps to eliminate corroded or frozen fasteners.
- Pins - Used in roller prosthetics & chains to ensure a better fit of parts (closer tolerance, non-lubricated) and longer lasting
- Marine shafts - better corrosion than types 304 and 316, with double the yield strength.
- Pin and hanger expansion joints for bridges - better corrosion, galling-resistance, low temperature toughness, & high charpy values at sub-zero temps compared to the A36 and A588 carbon steels commonly used.
