Controlled Expansion Alloys
NAS36
- JISPD
- UNSK93600
- DIN/EN1.3912
NAS36 is an alloy with nickel (36%) and iron as its main components. Because its coefficient of thermal expansion is extremely low, at about 1/10 that of 18-8 stainless steel, thermal stress caused by temperature changes can be held to a very low level, and complex shapes (wave, bellows, etc.) like those required with other low-temperature materials are not necessary. NAS36 also shows high toughness at low temperatures and provides excellent weldability. Nippon Yakin supplies NAS36 in sheet and strip forms.
