Frequently Asked Questions
Is SS 410 Washer magnetic?
SS 410 is magnetic in all states, so a quick magnet test easily separates it from 300-series stock.
Can SS 410 Washer be heat treated for extra hardness?
By heating and cooling SS 410, you can boost its hardness to 480-540 HB for tough, high-wear jobs.
What makes SS 410 Washer different from SS 304 Washer?
SS 410 can be heat-hardened but rusts easier, while SS 304 can’t be heat-hardened but fights rust much better.
