Grade 2 titanium handles most seawater and chemical service, but in hot, tight, chloride-rich crevices it can start to corrode where a plain commercially pure grade has no answer. Grade 12 is the grade the chemical and process industries reach for at that point: a small molybdenum and nickel addition that pushes back the crevice-corrosion limit and adds strength, at a fraction of the cost of the palladium grades. This guide covers what Grade 12 is, the exact conditions where Grade 2 gives out, how far Grade 12 extends the envelope, and how to specify and verify it. The Grade 12 titanium data sheet<\/a> carries the UNS R53400 identity and the Ti-0.3Mo-0.8Ni composition behind it.<\/p>\n

Grade 12 nedir ve Grade 2 ile Grade 7 aras\u0131nda nerede yer al\u0131r?<\/h2>\n

Grade 12, nominal 0,3% molibden ve 0,8% nikel ilaveli titanyumdur; UNS R53400, Werkstoff 3.7105 olarak tan\u0131mlan\u0131r.
