Frequently Asked Questions

  • What is a stabilized ferritic steel?


    Stabilized ferritic stainless steels contain higher chromium content than martensitic steels and contain small amounts of ferrite stabilizers (i.e. titanium) which preference the ferrite phase over the austenite phase. This makes them more resistant to chloride cracking.

  • What is the melting point of 439 stainless steel?


    It melts at 2741°F (1505°C).
