1. Peʻi e hoʻoponopono i ke kumu o kēia paukū
H13 make kilahoʻohana ʻia no ka hana ʻana i nā make forging me ka haʻahaʻa hopena kiʻekiʻe, make ka extrusion wela, make forging precision;make-casting make no ka aluminika, ke keleawe a me ko lakou mau alloys.

ʻO ia ka hoʻokomo ʻana o H13 air quench hardening hot work die steel mai ʻAmelika Hui Pū ʻIa.ʻO kona mau waiwai a me kona hoʻohana ʻana ua like nō ia me nā mea kila 4Cr5MoSiV, akā ma muli o kona ʻike kiʻekiʻe o ka vanadium, ʻoi aku ka maikaʻi o kāna hana wela (600 degere) ma mua o ke kila 4Cr5MoSiV.He mea kila kila me ka laulā o ka hoʻohana 'ana i ka wela hana make kila.
2. Nā hiʻohiʻona
Electroslag remelted kila, ke kila he kiʻekiʻe hardenability a me ka thermal māwae kuʻekuʻe, i loko o ke kila he kiʻekiʻe maʻiʻo o ke kalapona a me ka vanadium, maikaʻi lole pale pale, 'ano nawaliwali toughness, a me ka wela maikai.I nā wela kiʻekiʻe, ʻoi aku ka ikaika a me ka paʻakikī, ke kūpaʻa a me ka paʻakikī, nā waiwai mechanical piha maikaʻi a me ke kūpaʻa kūʻē kiʻekiʻe.
3. ʻO ke kinikini o ke kila
ʻO ke kila H13 he kila C-Cr-Mo-Si-V, i hoʻohana nuiʻia ma ka honua.I ka manawa like, ua nui nā ʻepekema mai nā ʻāina like ʻole i hana i ka noiʻi nui ma luna o ia mea a ke ʻimi nei i ka hoʻomaikaʻi ʻana o ka haku melemele.Hoʻohana nui ʻia ke kila a loaʻa iā ia nā hiʻohiʻona maikaʻi loa, i hoʻoholo nui ʻia e ka hui kemika o ke kila.ʻOiaʻiʻo, pono e hoʻemiʻia nā mea haumia i loko o ke kila.Hōʻike kekahi mau ʻikepili i ka wā o ka Rm he 1550MPa, hoʻemi ʻia ka ʻike 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, ʻo ka NADCA 207-2003 maʻamau e ʻōlelo ʻia e emi ka sulfur content o ke kila H13 premium ma mua o 0.005%, ʻoiai ʻo ka sulfur content o luna e emi iho ma mua o 0.003%S a me 0.015%P.Hoʻopili ʻia ka haku mele H13 ma lalo nei.
