Characteristics and main uses
Stainless steel with the particularity of being almost 100% non-magnetic in the hardened state thanks to the high manganese content. A layer of manganese oxide (whitish) can easily appear on the surface during heat treatment.
- Non-magnetic structure in all conditions
- High mechanical strength under cold rolling conditions. The resistance can be further increased by quenching, without any effect on the non-magnetic structure.
- High yield strength and energy storage capacity in cold rolled and tempered condition, which is important for spring applications.
- Operating temperature: up to 250 ° C (480 ° F)
- Corrosion resistance comparable to that of ASTM 301/304 (The high nitrogen content is known to be beneficial for resistance to pitting and crevice corrosion. However, all austenitic steels of this type are susceptible to cracking stress corrosion cracking (SCC) when in contact with chloride solutions at elevated temperatures.)
Main uses
- Spring and other components in the electronics and computer industries
- Printer components
- Springs for generators
- Electronic instrument enclosures
- Measuring instrument components
- Zipper parts and other components requiring non-magnetic properties
- Surgical tools
- Equipment for an open architecture in which surgery is performed simultaneously with magnetic resonance imaging.
- Reinforcement for high voltage cable where transmission losses must be kept low.
