He kila kuhiliʻole Martensitic kū i ka ʻino. Hōʻike ke kila 1.2085 i ke kūpaʻa ʻino maikaʻi loa ma ke ʻano paʻakikī me ka ʻili i hoʻoliʻi ʻia e hāʻawi i ke aniani finisih. Properties: Magnetizable steelm maikaʻi mechanical kū'ē a me ka paʻakikī, maikaʻi no ka hana 'ana i nā mea e pono ke kū'ē i ka aggressive plastics, maikaʻi mea hana machinability mahalo i kona sulfur maʻiʻo, kūpono no ka hana i loko o pulu lewa a me ka wai, kūpono no ka polishing, lole a me ka corrosion hōʻoia, a paʻa loa ka dimensionally i ka wā mālama wela.
Nā noi
ʻO nā ʻano mea hana ʻoki a pau - make a make-poloka i ka ʻoihana plastik e like me PVC, nā pahi, nā ʻoki, nā mea ʻokiʻoki, nā poni no ka hana ʻana i nā plastics, a me nā mea hana a me nā ana ana.
