ʻO ka wehewehe pōkole:
ʻO ka Surface finish 303 he kila kila ʻokiʻoki manuahi i loaʻa ka sulfur a me ka selenium, kēlā me kēia, no nā noi kahi e koi nui ʻia ai ka ʻoki manuahi a kiʻekiʻe ka hoʻopau ʻana o ka Surface.Hoʻomaikaʻi ʻo 303 stainless steel i ka hana ʻoki a me ke kūpaʻa paʻa wela kiʻekiʻe.ʻOi aku ka maikaʻi no nā lathes aunoa, bolts a me nā nati.
ʻO 303 ke kila kila he austenitic free-cutting stainless steel steel, i mea e hoʻomaikaʻi ai i ka hana o ke kila, hiki ke hoʻohui ʻia ʻaʻole i ʻoi aku ma mua o 0.60 Mo i ke kila, hiki ke pale aku i ka ablation, ʻoki maikaʻi i ka huahana a me ke kūpaʻa ahi.ʻO ke kūpaʻa ʻino.ʻO nā mea mechanical o 303 stainless steel annealed a de-stressed, ʻo ka ikaika tensile ʻo 515 MPA, ʻo 205 MPA ka hua, a ʻo ka elongation he 40%.ʻO ka paʻakikī maʻamau HRB 90-100, HRC 20-25 no ke kila kila 303 Nānā: HRB100 = HRC20
