    Change of magnetic properties of steel by thermal treatment!

    Hello, Does stainless steel loose its non-ferromagnetic properties when exposed to temperatures up to 850°C (Brazing) for a period of several hours. Final use will be at low temperature. The steels we are looking in are 304, 310, 316, 321. Thanks

    Searching non-magnetic low thermal expansion material!

    Hello, I am looking for a non-ferromagnetic, maybe a steel type and brazeable material which has an expansion coefficient in an order of magnitude of 8-15ppm/K from 20°C to 800°C , as mean value, would be ideal. Has anybody any ideas? Thanks!
