303 pā kila kila

303 pā kila kila

Ka nui o ka noi: ka ʻaila, ka uila, kemika, ka lāʻau lapaʻau, ka lole māmā, ka meaʻai, ka mīkini, ke kūkulu ʻana, ka mana nuklea, aerospace, ka pūʻali koa a me nā ʻoihana ʻē aʻe! ʻO 303 he kila kila ʻoki manuahi me ka sulfur a me ka selenium. Hoʻohana nui ʻia i nā noi kahi e koi ʻia ai ka ʻoki manuahi a me ka hoʻopau kiʻekiʻe. Hoʻomaikaʻi ʻo 303 stainless steel i ka hana ʻoki a me ke kūpaʻa wela kiʻekiʻe. ʻOi aku ka maikaʻi no ka lathe ʻakomi. ʻO nā kī a me nā nati. ʻO 303 kila kuhiliʻole he austenitic ʻoki kūʻokoʻa kūʻokoʻa aʻaʻa. I mea e hoʻomaikaʻi ai i ka hana o kēia kila, hiki ke hoʻohui ʻia ka molybdenum i ke kila ʻaʻole iʻoi aku ma mua o 0.60 ﹪, hiki ke pale aku i ka ablation, a ʻo ka huahana he machinability maikaʻi a me ke kūpaʻa ahi. ʻO ke kūpaʻa ʻino. Ma hope o ka hoʻopili ʻia ʻana a me ka destressed o nā mea mechanical o .303 stainless steel, ʻo 515MPa ka ikaika tensile, ʻo 205MPa ka hua, a ʻo ka elongation he 40%. ʻO ka paʻakikī maʻamau o ke kila kila 303 HRB 90-100, HRC 20-25, Nānā: HRB100 = HRC20
