ALLOY 316TI • UNS S31635 • WNR 1.4571

ʻO 316Ti (UNS S31635) kahi mana paʻa titanium o 316 molybdenum-bearing austenitic stainless steel. ʻOi aku ka paʻa ʻana o ka 316 alloys i ka corrosion maʻamau a me ka pitting/crevice corrosion ma mua o ka chromium-nickel austenitic stainless steels maʻamau e like me 304. Hāʻawi pū lākou i ke kolo kiʻekiʻe, ke kaumaha-rupture a me ka ikaika tensile i ka wela kiʻekiʻe. Hiki i ke kila kila kila kiʻekiʻe 316 ke maʻalahi i ka sensitisation, ka hoʻokumu ʻana o ka palena o ka palaoa chromium carbide ma nā mahana ma waena o 900 a me 1500 ° F (425 a 815 ° C) hiki ke hopena i ka corrosion intergranular. Loaʻa ke kū'ē i ka sensitization ma Alloy 316Ti me nā mea hoʻohui titanium e hoʻopaʻa i ka hoʻolālā e kū'ē i ka chromium carbide precipitation, ʻo ia ke kumu o ka sensitisation.
