1. E pelu e hoʻoponopono i ke kumu o kēia paukū
H13 make kilahoʻohana ʻia e hana i nā make forging me ka ukana hopena kiʻekiʻe, nā make extrusion wela, nā make forging precision; nā make die-casting no ka alumini, ke keleawe a me kā lākou mau mea hoʻohui.

ʻO ia ka hoʻolauna ʻana o ke kila make hana wela H13 air quench hardening mai ʻAmelika Hui Pū ʻIa. ʻO kona mau waiwai a me nā hoʻohana ʻana ua like like me ke kila 4Cr5MoSiV, akā ma muli o kona ʻike vanadium kiʻekiʻe, ʻoi aku ka maikaʻi o kāna hana mahana waena (600 degere) ma mua o ke kila 4Cr5MoSiV. He papa kila ia me nā ʻano hoʻohana like ʻole i ke kila make hana wela.
2. Nā Hiʻohiʻona
ʻO ke kila i hoʻoheheʻe hou ʻia e Electroslag, he kiʻekiʻe ka paʻakikī o ke kila a me ke kūpaʻa wela, ʻoi aku ka nui o ke kalapona a me ka vanadium i ke kila, kūpaʻa maikaʻi i ka ʻaʻahu ʻana, nāwaliwali iki ka paʻakikī, a me ke kūpaʻa wela maikaʻi. I nā mahana kiʻekiʻe, ʻoi aku ka ikaika a me ka paʻakikī, kūpaʻa kiʻekiʻe i ka ʻaʻahu ʻana a me ka paʻakikī, nā waiwai mechanical piha maikaʻi loa a me ke kūpaʻa kiʻekiʻe i ka pale ʻana i ka tempering.
3. ʻO ke ʻano kemika o ke kila
He kila C-Cr-Mo-Si-V ke kila H13, kahi i hoʻohana nui ʻia ma ka honua. I ka manawa like, ua hana nui nā kānaka ʻepekema mai nā ʻāina like ʻole i noiʻi nui ma luna o ia mea a ke ʻimi nei i ka hoʻomaikaʻi ʻana i ka hoʻohuihui kemika. Hoʻohana nui ʻia ke kila a he mau ʻano maikaʻi loa, i hoʻoholo nui ʻia e ka hoʻohuihui kemika o ke kila. ʻOiaʻiʻo, pono e hoʻemi ʻia nā mea haumia i loko o ke kila. Hōʻike kekahi ʻikepili i ka wā ʻo Rm he 1550MPa, ua hoʻemi ʻia ka nui o ka sulfur o ka mea mai 0.005% a i 0.003%, kahi e hoʻonui ai i ka paʻakikī o ka hopena ma kahi o 13J. ʻIke loa, ua ʻōlelo ke kūlana NADCA 207-2003 ʻo ka nui o ka sulfur o ke kila H13 premium e emi iho ma mua o 0.005%, ʻoiai ʻo ka nui o ka sulfur o ka superior e emi iho ma mua o 0.003%S a me 0.015%P. Ua kālailai ʻia ka hoʻohuihui o ke kila H13 ma lalo nei.

Kalapona: ʻO ka ʻike kalapona o ke kila ʻAmelika AISI H13, UNS T20813, ASTM (ka mana hou loa) H13 a me FED QQ-T-570 H13 he (0.32 ~ 0.45)%, ʻo ia ka ʻike kalapona nui loa o nā mea āpauNā kila H13. ʻĀkea. ʻO ka nui o ke kalapona o ka X40CrMoV5-1 Kelemania a me 1.2344 he (0.37~0.43)%, a he haiki ka pae o ke kalapona. Ma ka DIN17350 Kelemania, ʻo ka nui o ke kalapona o X38CrMoV5-1 he (0.36~0.42)%. ʻO ka nui o ke kalapona o SKD 61 ma Iapana he (0.32~0.42)%. ʻO ka nui o ke kalapona o 4Cr5MoSiV1 a me SM 4Cr5MoSiV1 ma ka GB/T 1299 a me YB/T 094 o koʻu ʻāina he (0.32~0.42)% a me (0.32~0.45)%, ʻo ia hoʻi nā mea like me SKD61 a me AISI H13. Ma ke ʻano kūikawā, pono e kuhikuhi ʻia ua kuhikuhi ʻia ka ʻike kalapona o ke kila H13 ma nā kūlana o ka North American Die Casting Association NADCA 207-90, 207-97 a me 207-2003 ma ke ʻano he (0.37 ~ 0.42)%.

Pono ke kila H13 me 5% Cr e paʻakikī kiʻekiʻe, no laila e mālama ʻia kona ʻike C ma kahi pae e hana ai i kahi liʻiliʻi o nā hui alloy C. Ua kuhikuhi ʻo Woodyatt lāua ʻo Krauss ma ke kiʻikuhi pae ternary Fe-Cr-C ma 870 ℃, ʻoi aku ka maikaʻi o ke kūlana o ke kila H13 ma ka hui ʻana o nā ʻāpana ʻekolu-pae austenite A a me (A+M3C+M7C3). ʻO ka ʻike C e pili ana ma kahi o 0.4%. Ua hōʻailona pū ka helu i ka hoʻonui ʻia ʻana o ka nui o C a i ʻole Cr e hoʻonui i ka nui o M7C3, a me nā kila A2 a me D2 me ke kū'ē ʻana i ke kapa komo kiʻekiʻe no ka hoʻohālikelike ʻana. He mea nui hoʻi e mālama i kahi ʻike C haʻahaʻa e hana i ka Ms point o ke kila e lawe i kahi pae wela kiʻekiʻe (ʻo ka Ms o ke kila H13 i wehewehe pinepine ʻia he 340 ℃), i hiki ai ke kinai ʻia ke kila i ka mahana o ka lumi. E kiʻi i ke ʻano hui hui ʻia me ka martensite me kahi liʻiliʻi o ke koena A a me ke koena like, a e kiʻi i kahi ʻano martensite i hoʻomaʻamaʻa like ʻia ma hope o ka hoʻomaʻamaʻa ʻana. E pale i ka hoʻololi ʻana i ka nui o ka austenite i mālama ʻia ma ka mahana hana e hoʻopilikia ai i ka hana hana a i ʻole ka deformation o ka workpiece. Pono e hoʻololi piha ʻia kēia mau liʻiliʻi o ka austenite i mālama ʻia i nā kaʻina hana hoʻomaʻamaʻa ʻelua a ʻekolu paha ma hope o ka quenching. Ma ke ala, ua kuhikuhi ʻia ma ʻaneʻi ʻo ke ʻano martensite i loaʻa ma hope o ka quenching o ke kila H13 he lath M + kahi liʻiliʻi o ka flake M + kahi liʻiliʻi o ke koena A. ʻO nā carbides alloy maikaʻi loa i hoʻoulu ʻia ma ka lath M ma hope o ka hoʻomaʻamaʻa ʻana. Ua hana pū nā haumāna kūloko i kekahi mau hana
