Nā mea hana a me ka hana ʻana
1. Hiki ke hoʻopau wela ʻia a huki anu ʻia paha nā paipu kila inoa, a ua hana ʻia ka mālama wela hope loa e like me ke kūlana.
2. Ke kila pae P2 a me P12. Pono e hana ʻia kēia mau papa kila ʻelua me ka hoʻohana ʻana i ke kaʻina hana hoʻoheheʻe ʻana i nā hua coarse. Inā he mau koi kūikawā no ka nui o nā hua a i ʻole ke kaʻina hana deoxidation, pono e ʻaelike ʻia e ka mea kūʻai a me ka mea hana kila.
3. Ka mālama wela
1. Koe wale nō ke kila PSC, P23, P91, P92, P122 a me P911 a e like me ka mea i kuhikuhi ʻia, e hoʻomehana hou ʻia nā papa āpau o nā paipu inoa a hoʻolako ʻia i loko o kahi mokuʻāina annealed piha, isothermal annealed a i ʻole normalized a tempered. Inā hoʻolako ʻia i loko o ke mokuʻāina normalized a tempered, ʻo ka mahana tempering haʻahaʻa loa no ke kila P5, P5B, P9, P21 a me P22 he 675°C. ʻO ka mahana tempering haʻahaʻa loa no ke kila P1, P2, P11, P12 a me P15 he 650 ℃.
2. Pono ka hoʻomaʻamaʻa wela hope loa o ke kila P92 a me P911 e hoʻomaʻamaʻa ma ka liʻiliʻi he 1040 ℃ a me ka hoʻomaʻamaʻa ʻana ma ka liʻiliʻi he 730 ℃.
