ʻO ASTM A638 660 Paʻa Kūleʻa Kūleʻa
ʻO ka wehewehe pōkole:
ʻO 660A e pili ana i kahi kūlana kūikawā o ka alloy A286 (UNS S66286), he kila kila kila ikaika, wela kiʻekiʻe, a me ka corrosion.
660A pae hao hao:
ʻO ka ASTM A453 Grade 660 kahi mea paʻakikī austenitic stainless steel i hoʻohana nui ʻia no ka hoʻopaʻa ʻana i ka wela wela a me nā mea bolting. ʻO ke kūlana 660A o A286 stainless steel he solution annealed, e hāʻawi ana i ke koena o ka ikaika kiʻekiʻe, ke ʻano maikaʻi, a me ka pale ʻana i ka corrosion. ʻO kēia ka mea kūpono no ka noi ʻana i nā noi i ka aerospace, automotive, a me nā ʻoihana ʻoihana kahi e hana pono ai nā mea hana ma lalo o nā kūlana kiʻekiʻe-koʻikoʻi a me nā kūlana kiʻekiʻe. , me ka wai kai, nā ʻakika māmā, a me nā alkali.

Papa 660 ma ka Papa A/B/C/D Bar Noi:
Hoʻopili ʻo ASTM A453/A453M i ka kikoʻī no ka bolting wela kiʻekiʻe me nā coefficients hoʻonui i hoʻohālikelike ʻia me ke kila stainless austenitic. ʻO kekahi o nā māka i hoʻohana maʻamau ʻia ʻo Grade 660 bolts. Hana mākou i nā bolts stud,nā kī hex, nā kī hoʻonui,nā lāʻau kaula, a me nā mea hou aku e like me ka A453 Grade 660 i nā Papa A, B, C, a me D, i manaʻo ʻia no nā noi ʻenehana loea.
No ke aha e koho ai iā mākou?
•Hiki iā ʻoe ke loaʻa ka mea kūpono e like me kāu koi ma ka liʻiliʻi loa o ke kumu kūʻai.
•Hāʻawi pū mākou i nā Reworks, FOB, CFR, CIF, a me nā kumukūʻai hoʻopuka puka i ka puka. Manaʻo mākou iā ʻoe e hana i ka hana no ka hoʻouna ʻana e ʻoi aku ka waiwai.
•Hiki ke hōʻoia ʻia nā mea a mākou e hāʻawi ai, mai ka palapala hōʻike maka a hiki i ka ʻōlelo kikoʻī hope. (E hōʻike ʻia nā hōʻike ma ke koi)
•Ke hōʻoiaʻiʻo nei mākou e hāʻawi i kahi pane i loko o 24 mau hola (maʻamau i ka hola hoʻokahi)
•Hāʻawi i ka hōʻike SGS TUV.
•Hoʻolaʻa piha mākou i kā mākou mea kūʻai. Inā ʻaʻole hiki ke hoʻokō i kāu mau koi ma hope o ka nānā ʻana i nā koho āpau, ʻaʻole mākou e alakaʻi hewa iā ʻoe ma ka hana ʻana i nā ʻōlelo hoʻohiki wahaheʻe e hoʻokumu ai i nā pilina mea kūʻai aku.
•Hāʻawi i ka lawelawe hoʻokahi.
Hoʻopili:
1. He mea koʻikoʻi ka hoʻopaʻa ʻana ma ka hihia o ka hoʻouna ʻana i ka honua kahi e hele ai ka lawe ʻana ma nā ala like ʻole e hiki ai i ka hopena hope loa, no laila ke kau nei mākou i ka hopohopo kūikawā e pili ana i ka ʻeke.
2. Hoʻopili ʻo Saky Steel i kā mākou waiwai ma nā ʻano he nui e pili ana i nā huahana. Hoʻopili mākou i kā mākou huahana ma nā ʻano he nui, e like me,
