Below, I give you a few choices and of course will point out BUMAX as the in between a supper alloy and standard 316. www.bumax.us
Note: this is a limited list and yes I could mention 20 other materials,but pricing will not be satisfactory on the exotics. So I list a few and hopefully this will assist you with the start of finding something other than standard 316 stainless steel fasteners.
|Grade||Why it might be chosen instead of standard 316?|
|Bumax A4-316L||2x Tensile strength 150ksi, 2x corrosion resistance, up to 60% less expensive than exotics|
|316Ti||Better resistance to temperatures of around 600-900°C is needed.|
|316N||Higher strength than standard 316.|
|317L||Higher resistance to chlorides than 316L, but with similar resistance to stress corrosion cracking.|
|904L||Much higher resistance to chlorides at elevated temperatures, with good formability|
|2205||Much higher resistance to chlorides at elevated temperatures, and higher strength than 316|
