Heat Treatment Grades and Performance Distinctions: The distinguishing hiʻona o17-4PHʻo ia ka maʻalahi o ka hoʻoponopono ʻana i nā pae ikaika ma o ka hoʻololi ʻana i nā kaʻina hana wela.ʻO ka hoʻololi ʻana i ka martensite a me ka paʻakikī paʻakikī o ka ua ke kumu mua o ka hoʻoikaika ʻana.ʻO nā māka lapaʻau wela maʻamau i ka mākeke ʻo H1150D, H1150, H1025, a me H900.Hōʻike kekahi mau mea kūʻai aku i ka pono o nā mea 17-4PH i ka wā kūʻai, e koi ana i ka mālama wela.ʻOiai he ʻokoʻa nā māka mālama wela, pono e hoʻokaʻawale ʻia nā kūlana hoʻohana like ʻole a me nā koi hopena.ʻO ka wela o ka hoʻoponopono ʻana ua like ia no ka hoʻomaloʻo wikiwiki ʻana, a hoʻoponopono ka ʻelemakule i ka mahana a me ka helu o nā pōʻai ʻelemakule e pili ana i ka ikaika i koi ʻia.
Nā noi:
Ma muli o kāna mau waiwai mechanical a me ka corrosion-resistant, hoʻohana nui ʻia ʻo 17-4PH i nā ʻoihana e like me ka petrochemical, ka mana nuklea, aerospace, pūʻali koa, moana, automotive, a me nā kahua lapaʻau.I ka wā e hiki mai ana, ua manaʻo ʻia e loaʻa kahi hiʻohiʻona mākeke e like me ke kila duplex.
