25Cr2MoVA pepa kila ʻōwili wela

① ʻO nā huahelu ʻelua ma ka hoʻomaka ʻana o ka helu kila e hōʻike i ka ʻike kalapona o ke kila, i hōʻike ʻia i loko o ka ʻumi kaukani o ka maʻamau kalapona awelika, e like me 40Cr, 25Cr2MoVA alloy tube
② ʻO nā mea hoʻohui nui i ke kila, koe wale nā ​​mea microalloying pākahi, hōʻike maʻamau i loko o ka hapa hapa. Ke emi iho ka awelika o ka alloy ma mua o 1.5%, ma ka helu kila, ʻaʻole i hōʻike ʻia ka ʻike. Eia nō naʻe, i nā kūlana kūikawā, maʻalahi ka huikau, a hiki ke kaha ʻia ka helu "1" ma hope o ka hōʻailona element, e like me ka helu kila "12CrMoV" a me "12Cr1MoV", ʻo ka mea mua he chromium maʻiʻo o 0.4-0.6. %, he 0.9-1.2% ka chromium o ka hope, a ua like ke koena. Ke hōʻike ʻia ka ʻike ma hope o ka hōʻailona element, hiki ke hōʻike ʻia e like me 2, 3, 4... etc. , 18Cr2Ni4WA.
③ ʻO nā mea hoʻohui like me ka vanadium V, ka titanium Ti, ka alumini AL, ka boron B, a me ka honua laha ʻole RE i loko o ke kila he mau mea microalloying a pau. ʻOiai he haʻahaʻa loa ka maʻiʻo, pono ke kaha ʻia i ka helu kila. No ka laʻana, ma 20MnVB kila. ʻO ka Vanadium ka 0.07-0.12%, a ʻo ka boron ka 0.001-0.005%.
④Pono ke kila kiʻekiʻe kiʻekiʻe e hoʻohui i ka "A" ma ka hope o ka helu kila e hoʻokaʻawale iā ia mai ke kila kila kiʻekiʻe.
⑤ Ke kila kila kila kūikawā, ua kau mua ʻia ka helu kila (a i ʻole ka suffix) me ka hōʻailona e hōʻike ana i ke kumu o ke kila. No ka laʻana, 30CrMnSi kila kūikawā no riveting screws, ka helu kila i hoike ia e like me ML30CrMnSi.
ʻO nā paipu huila a me nā paipu liʻiliʻi he pili a ʻokoʻa, a ʻaʻole pono e huikau.
Hoʻohālikelike ʻia ka paipu Alloy e ka paipu kila e like me ka mea hana (ʻo ia hoʻi, mea), e like me ka inoa i hōʻike ʻia, he paipu i hana ʻia me ka alloy; ʻoiai ua wehewehe ʻia ka paipu seamless e ka paipu kila e like me ke kaʻina hana (seamless a seamless), ʻo ka ʻokoʻa mai ka seamless pipe he Seam pipes, me nā paipu wili wili pololei a me nā paipu spiral.

Hiki iā mākou ke hana i ka 25Cr2MoVA i kēia mau kikoʻī:

Ke kila lāʻau pōʻai: 1mm a 3000mm

Ke kila ʻano huinaha: 1mm a 2000mm

Pā kila: 0.1mm a 2500mm

Laulā: 10mm a 2500mm

Lenth: Hiki iā mākou ke hoʻolako i kēlā me kēia lenth ma muli o ke koi o ka mea kūʻai.

Ka hana ʻana: ʻO nā ʻāʻī me nā ʻaoʻao/pipe/tubes/slugs/donuts/cubes/nā ʻano ʻano ʻē aʻe

Nā paipu: OD: φ6-219 mm, me ka mānoanoa o ka paia mai ka 1-35 mm.

Kūlana o ka waiwai i pau: hoʻopaʻa wela/wili wela + annealing/normalizing + tempering/quenching + tempering/kekahi kūlana e pili ana i ka koi o ka mea kūʻai.

Nā kūlana o ka ʻili: hoʻonui ʻia (hoʻopau hana wela)/ground/machining rough/machining maikaʻi/ma muli o ke koi o ka mea kūʻai.

Na kapuahi no ka hana metala: arc electrode + LF/VD/VOD/ESR/Vacuum consumable electrode.

Nānā kani ultrasonic: 100% nānā ultrasonic no nā hemahema a i ʻole ma muli o ke koi o ka mea kūʻai aku lawelawe maikaʻi loa no nā ʻano ʻoihana āpau, me nā pono o nā ʻenehana, nā lako a me nā kumukūʻai.

Hāʻawi mākou iā ʻoe me ko mākou ʻoiaʻiʻo, kūpaʻa, a me ka ʻoihana.
