317L Stainless Steel Overview
317L ine molybdenum inobereka, yakaderera kabhoni yemukati "L" giredhiaustenitic simbi isina tsvinaiyo inopa yakagadziridzwa corrosion kuramba pamusoro pe304L uye 316L simbi isina tsvina. Iyo yakaderera kabhoni inopa kuramba kwekunzwa panguva yewelding uye mamwe maitiro ekupisa.
317L haisi magineti mune annealed mamiriro asi inogona kuita zvishoma magineti nekuda kwewelding.
Corrosion Resistance
317L ine yakanakisa corrosion resistance mumhando dzakasiyana siyana dzemakemikari, kunyanya munzvimbo dzine acidic chloride dzakadai seidzo dzinosangana mumapupi nemapepa. Kuwedzera mazinga echromium, nickel uye molybdenum zvichienzaniswa ne316L simbi isina tsvina inovandudza kuramba kune chloride pitting uye general corrosion. Kupokana kunowedzera ne molybdenum alloy content. 317L inoshingirira sulfuric acid concentrations kusvika 5 percent patembiricha inosvika 120°F (49°C). Pakupisa kuri pasi pe100°F (38°C) iyi alloy ine yakanakisa kuramba kune mhinduro dzepamusoro. Nekudaro, bvunzo dzesevhisi dzinokurudzirwa kuti dzizvidavirire kune zvinokanganisa zvemamiriro ekushanda anogona kukanganisa maitiro ekuora. Mune maitiro apo kusvibiswa kwemagasi ane sulfur-bearing kunoitika, 317L inonyanya kupikisa kurwisa panzvimbo ye condensation pane yakajairwa alloy 316. Kugadziriswa kweasidhi kune simba rakajeka pamusoro pehuwandu hwekurwisa mumamiriro ezvinhu akadaro uye inofanira kunyatsogadziriswa nebasa. miedzo.

Welding 317L
317L inosungirirwa nyore nyore nehuwandu hwakazara hwemaitiro ekugadzira welding (kunze kwe oxyacetylene). AWS E317L/ER317L simbi yekuzadza simbi kana austenitic, yakaderera kabhoni yekuzadza simbi ine molybdenum yemukati yakakwira kupfuura iyo ye317L, kana nickel-base yekuzadza simbi ine yakakwana chromium uye molybdenum zvirimo kudarika corrosion resistance ye317L inofanira kushandiswa simbi ye317L.
