    Can I buy AL-6X plates ?

    I am trying to find out the correlation between PRE and CPT of stainless steels. Thus, I need 'AL-6X and 254SFER' but I couldn't find where I can buy its plate. Would you please let me know where I can buy 'AL-6X and 254SFER plate' ?(for examples, any thickness(~6mm), several 30x30 cm plates)

    Why does PREN be greater than 32 for sea water?

    In AL6XN.com homepage, I found "For seawater, PREN must be greater than 32" in FAQs. I am wondering why PREN must be greater than 32. Is PRE 32 special criteria for seawater? Would you please let me know why PRE must be greater than 32 ? Thanks

    Why does PREN be greater than 32 for sea water?

    I read the Q&A elsewhere - for seawater, PREN of stainless steels must be greater than 32. I want to know why PREN must be greater than 32. Why 32? Another question, how is the lifetime of 316L stainless steel piping in 40C, seawater cooling condenser tubing? Thanks,
