Chitsulo chosapanga dzimbiri 317

317 chitsulo chosapanga dzimbiri, chomwe chimadziwikanso kuti UNS S31700 ndi Grade 317, chimakhala ndi 18% mpaka 20% chromium ndi 11% mpaka 15% faifi tambala pamodzi ndi kuchuluka kwa carbon, phosphorous, sulfure, silikoni komanso yogwirizana ndi iron.UNS S31700 /S31703 yomwe imadziwika kuti Stainless Steel 317/317L Dual Certified ndi mtundu wocheperako wa kaboni wa Stainless Steel 317 wamapangidwe owotcherera.

Mawonekedwe ndi maubwino a Stainless Steel 317 ndi 317/317L Zotsimikizika Pawiri zimaphatikizanso mphamvu zowonjezera, kukana kwa dzimbiri (kuphatikiza ming'alu ndi pitting), kulimba kwamphamvu komanso kupsinjika kwapang'onopang'ono. Makalasi onsewa amakana kulowa mu acetic ndi phosphoric acid. Pankhani ya kuzizira kwa Stainless Steel 317 ndi 317/317L Dual Certified, kupondaponda, kumeta ubweya, kujambula ndi mutu zonse zitha kuchitidwa bwino. Kuphatikiza apo, annealing itha kuchitidwa pamagiredi onse awiri pakati pa 1850 F ndi 2050 F, ndikutsatiridwa ndi kuzizira kofulumira. Kuphatikiza apo, njira zonse zogwirira ntchito zotentha zimatheka ndi Stainless Steel 317 ndi 317/317L Dual Certified, pakati pa 2100 F ndi 2300 F.

Gulu laling'ono: Chitsulo; Chitsulo chosapanga dzimbiri; T 300 Series Stainless Steel

Mawu Ofunika Kwambiri: Plate, sheet, and chubu specs ndi ASTM A-240

Chemical Composition

317L imawotcherera mosavuta ndi njira zambiri zowotcherera (kupatula oxyacetylene). AWS E317L/ ER317L zitsulo zodzaza ndi zitsulo kapena austenitic, zitsulo zotsika kaboni zodzaza ndi molybdenum zokwera kuposa 317L, kapena chitsulo cha nickel-base filler chokhala ndi chromium ndi molybdenum yokwanira kupitilira kukana kwa dzimbiri kwa 317L ziyenera kugwiritsidwa ntchito powotcherera 317L. zitsulo.
