317/317L kila kuhiliʻole 6.35*0.70mm paipu wili/puʻu pololei

317/317L kila kuhiliʻole 6.35*0.70mm paipu wili ʻia/pololei.

ʻO ka wehewehe pōkole:

ʻO ka maʻiʻo molybdenum kiʻekiʻe o Alloy 317L e hōʻoiaʻiʻo i ke kūpaʻa o ka corrosion ākea ākea a kūloko i ka hapa nui o ka media ke hoʻohālikelike ʻia me 304/304L a me 316/316L mau kila kila.ʻAʻole e ʻino nā kaiapuni ʻaʻole 304/304L kila kila ʻole i ka 317L.Eia naʻe, hoʻokahi mea ʻokoʻa, ʻo ia ka mea hoʻoneʻe ikaika e like me ka waikawa nitric.ʻAʻole hana maikaʻi nā huila i loaʻa i ka molybdenum i kēia mau kaiapuni.

Loaʻa i ka Alloy 317L ke kūpaʻa maikaʻi loa i ka nui o nā mea kemika.Kūʻē ia i ka hoʻouka ʻana i ka sulfuric acid, acidic chlorine a me ka phosphoric acid.Hoʻohana ʻia ia i ka lawelawe ʻana i nā mea momona a me nā momona momona i loaʻa pinepine i nā meaʻai a me nā noi hana lāʻau.

Pono ka pale ʻino o 317 a me 317L i kēlā me kēia kaiapuni.ʻO kahi hoʻokahi wale nō kahi e hōʻike ʻia ai ka huila i nā mahana i loko o ka chromium carbide precipitation range o 800 – 1500°F (427 – 816°C).Ma muli o kona haʻahaʻa kalapona haʻahaʻa, ʻo 317L ka mea i makemake nui ʻia i kēia lawelawe e kiaʻi ai i ka corrosion intergranular.

317/317L kila kuhiliʻole 6.35*0.70mm paipu wili ʻia/pololei.

Ma keʻano laulā, hoʻopili ʻia nā kila kila austenitic i ka chloride stress corrosion ma ka lawelawe halide.ʻOiai ʻoi aku ka pale ʻana o 317L i ke koʻikoʻi ʻana o ka corrosion ma mua o 304/304L stainless steels, no ka mea, ʻoi aku ka kiʻekiʻe o ka molybdenum maʻiʻo, hiki ke maʻalahi.

317/317L kila kuhiliʻole 6.35*0.70mm paipu wili ʻia/pololei.

ʻO ke kiʻekiʻe o ka chromium, molybdenum a me ka nitrogen maʻiʻo o 317L e hoʻonui i kona hiki ke pale aku i ka lua a me ka crevice corrosion i mua o nā chlorides a me nā halides ʻē aʻe.ʻO ka Pitting Resistance Equivalent me ka helu Nitrogen (PREN) kahi ana pili o ke kū'ē pitting.Hāʻawi ka pakuhi aʻe i kahi hoʻohālikelike Alloy 317L a me nā mea kila kila austenitic ʻē aʻe.
