27SiMn mau kaola kila i olokaaia wela

Loaʻa iā 27SiMn ka machinability maikaʻi a me ke anuanu deformation plasticity. Mālama ʻo ia i ka ikaika kiʻekiʻe a me ka pale ʻana i ka wā o ka mālama ʻana i ka wela a me ka paʻakikī kiʻekiʻe i ka wā e hoʻopau ai i ka wai. Hoʻohana nui ʻia ke kila 27SiMn i nā kaʻa, ʻaila, ʻoihana kemika, ʻoihana lawe moku, 27SiMn nā paipu kila i hoʻomaʻamaʻa ʻia a hoʻomaʻamaʻa ʻia, ʻaila ʻia ka phosphate i loko a i waho, hoʻohana maʻamau no ka hana ʻana i nā ʻāpana stamping wela e koi ana i ka paʻakikī kiʻekiʻe a me ka pale ʻana, e like me nā ʻāpana hydraulic like ʻole. .
