APPLICATIONS |
SS-303 N1
SS-304 N1
SS-316 N1
(6.5-6.8g/cc) |
Austenitic |
‘Low-temperature’ sintered
in a nitrogen atmosphere to provide a nitrogen-induced wear surface,
good strength, and lower ductility |
Pump components, threaded marine components,
non-magnetic housings |
SS-303 N2
SS-304 N2
SS-316 N2
(6.6-7.0g/cc) |
Austenitic |
‘High-temperature’ sintered
in a nitrogen atmosphere to provide a nitrogen induced wear surface,
high strength, and improved ductility |
Pump components, threaded marine components,
non-magnetic housings, all requiring improved physical properties |
SS-303L
SS-304L
SS-316L
(6.8-7.1g/cc) |
Austenitic |
‘High-temperature’ sintered
in either partial vacuum or a hydrogen atmosphere to improve
the ductility and corrosion resistance |
Food service equipment, pump components,
marine components, and non-magnetic housings |
Ultimet 16
(7.2g/cc to 7.5g/cc) |
Duplex |
‘High-temperature’ sintered
in a hydrogen atmosphere significantly improving the ductility
and corrosion resistance |
Hardware, locks, fittings, flanges, pump
components, and housings |
SS-409L
SS-409CB
SS-410L
SS-430L
SS-434L
6.9 to 7.3g/cc |
Ferritic |
‘High-temperature’ sintered
in a hydrogen atmosphere, densities above 7.2 g/cc optimize the
welding characteristics and magnetic properties |
Magnetic probes and sensors, armatures,
and pole pieces requiring protection from atmospheric corrosion
and general oxidation |
SS-410N2
SS-430N2
SS-434N2
6.9 to 7.3g/cc |
Ferritic |
‘High-temperature’ sintered
in a nitrogen atmosphere, slightly higher strength than ‘L’ series
with reduced corrosion resistance and magnetic response |
Magnetic probes and sensors, armatures,
and pole pieces requiring protection from atmospheric corrosion
and general oxidation |
SS-410HT SS-420HT SS-440HT 6.6 to 7.2g/cc |
Martensitic |
‘High-temperature’ sintered
in a hydrogen atmosphere increasing hardness and strength over
other stainless steels |
Wear plates, fuel injection nozzles, and
cutting instruments |
