ʻO FIXDEX Factory2 ss304 ss316 piha piha i ke koʻokoʻo wili / pae ʻauʻau / hale hana pahu pahu

Pehea e hoʻomaopopo ai i ka maikaʻi o ke koʻokoʻo wiliwili kila/ʻauʻau wili/ ʻūlū stud?

1. ʻIke Magnetic

Ua ʻōlelo ʻoe he mea magnetic, pololei! He ʻoiaʻiʻo nō ʻaʻole ia he magnetic! ʻOiaʻiʻo, ʻokoʻa lākou. Ua ʻike mākou a pau ua māhele ʻia ke kila kuhiliʻole i ka austenitic stainless steel a me ka ferritic stainless steel. Austenitic kuhiliʻole kila he non-magnetic, oiai ferritic kuhiliʻole kila he ikaika magnetic kila. Ma o ke ʻano o nā hoʻokolohua, ua hōʻike ʻia e loaʻa i ka austenitic stainless steel ka magnetism maʻalahi ma lalo o kekahi mau kūlana kūikawā, akā ʻaʻole ia ma lalo o nā kūlana maʻamau.

2. E hana i ka ho'āʻo kikoʻī nitric acid

I nā manawa he nui, paʻakikī ke hoʻokaʻawale i ka 200 series, 300 series, 400 series a me nā ʻano ʻano kila kila ʻē aʻe me ka maka maka. ʻO ka nitric acid point test ke ala hoʻāʻo intuitive loa e hoʻāʻo ai i ke kūpaʻa corrosion o ka substrate. ʻO ka mea maʻamau, e ʻino wale ʻia ka moʻo 400 i ka wā o ka hoʻāʻo ʻana, aʻo ka 200 series stainless steel me ka haʻahaʻa haʻahaʻa kūʻē ʻino e loaʻa nā hōʻailona corrosion.

3. Hoao paakiki

Inā hōʻike ka austenitic stainless steel i kekahi magnetism i ka wā e ʻōwili ʻia ai ke anuanu ma lalo o ke kaomi ʻana o ka lewa, a laila ʻaʻole kūpono ka hoʻāʻo magnetic mua i ʻōlelo ʻia; no laila pono mākou e wela i ke kila kila ma kahi o 1000-1100 ℃ a laila e kinai i ka wai e hoʻopau i ka magnetism o ka austenitic stainless steel a hoʻāʻo i ka paʻakikī. ʻO ka paʻakikī o ka austenitic stainless steel ma lalo o RB85

Kahi mea hou aʻe

ʻO ka paʻakikī o 430, 430F a me 466 kila ma lalo o Rc 24

ʻO ka paʻakikī o 410, 414, 416 a me 431 ʻo Rc36~43

ʻO ka paʻakikī o ke kalapona kiʻekiʻe 420, 420F, 440A, B, C a me F ʻo Rc50 ~ 60.

Inā ʻo Rc50 ~ 55 ka paʻakikī, he 420 kila paha

ʻO ka paʻakikī o nā hoʻohālike 440A a me B i hoʻopau ʻia ʻo Rc55 ~ 60

ʻO ka waiwai Rc o 60 a i ʻole he kila 440C.

4. Ma o ka machining inspection

Inā ho'āʻo ʻia ke kila kuhiliʻole he ʻano kumu, ʻōlelo ʻia e lawe i kahi lathe maʻamau a i ʻole CNC lathe no ka nānā ʻana i ka mīkini, akā aia nō nā palena. He kūpono wale kēia ʻano no ke kila maʻalahi e ʻoki ʻia a me ke kila kila maʻamau, e like me 303, 416, 420F, 430F, 440F. ʻIke ʻia ke ʻano o ke kila ma ke ʻano o nā ʻāpana huli. ʻO kēia ʻano kila maʻalahi e hoʻokuʻu i kahi ʻala maikaʻi ʻole ke huli ʻia i kahi kūlana maloʻo.

5. ʻIke ʻia ka waikawa Phosphoric

He ala ʻike kēia a mākou e hoʻohana pinepine ai i ke ola o kēlā me kēia lā. Hoʻohana ʻia kēia ʻano hana e hoʻokaʻawale i ke kila kila chromium-nickel. E hoʻohui i ka waika phosphoric concentrated i ka solution 0.5% sodium fluoride a hoʻomehana iā 60-66 ℃.

6. ʻIke ʻia e ke kiko keleawe sulfate

Hiki i kēia ʻano ke ʻike i ke kila kalapona maʻamau a me ke kila kila. Pono ka ʻike o ka hopena keleawe sulfate ma waena o 5% a me 10%. Ke hoʻokuʻu ʻia ma luna o ke kila e hoʻāʻo ʻia, e hoʻokumu ʻia kahi ʻāpana keleawe keleawe ma luna o ka ʻili o ke kila kalapona maʻamau i loko o kekahi mau kekona, ʻoiai ʻo ka ʻili o ke kila kila ʻaʻole e loli.

7. Ka ʻike ʻana i ka hoʻonā sulfuric acid

Hiki i kēia ʻano ke hoʻokaʻawale i nā kila kila 302, 304, 316, a me 317. E hoʻomākaukau i ka sulfuric acid me ka manaʻo o 20% a 30% a me kahi mahana ma kahi o 70 ° C, a hoʻokomo i ke kila e ho'āʻoʻia i loko o ka hopena. ʻO 302 a me 304 mau mea kila kila e hoʻohua i ka nui o nā ʻōpū i ka wā e hālāwai ai lākou i ka hopena a lilo i ʻeleʻele i loko o kekahi mau minuke;

ʻO ka mea ʻē aʻe, ʻaʻole e hōʻike ka 316 a me 317 stainless steels i ka hopena nui i ka hopena, a ʻaʻole e lilo i ʻeleʻele i loko o 10 a 15 mau minuke.

8. Ka ʻike kiko waika anu

Hiki ke hoʻokaʻawale ʻia ke ʻano like o ke kila kila ma ka hoʻoheheʻe ʻana i kahi solution 20% sulfuric acid ma luna o ka ʻili o ka hāpana i hoʻoheheʻe ʻia, hoʻomaʻemaʻe ʻia, hoʻomaʻemaʻe ʻia a i ʻole ʻia.

E hoʻokuʻu i kekahi mau kulu o ka waiʻakika ma ka ʻili o kēlā me kēia hāpana. Ma lalo o ka hana o ka waiʻawaʻawa, 302 a me 304 mau kila kuhiliʻole e hoʻopili ikaikaʻia a lilo iʻeleʻele, e hōʻike ana i kaʻeleʻele-ʻeleʻele aʻeleʻele paha, a laila ua hoʻokumuʻia nā kristal'ōmaʻomaʻo i loko o ka hopena;

ʻO 316 ke kila kuhiliʻole e hoʻoheheʻe mālie a huli mālie i ka ʻeleʻele-melemele, a laila lilo i ʻeleʻele-ʻeleʻele, a i ka hopena i hana ʻia kekahi mau kristal ʻeleʻele ʻōmaʻomaʻo māmā i ka hopena; ʻOi aku ka mālie o ka hopena o ka 317 stainless steel.

9. Nānā ma o nā ʻulaʻula

Hoʻohana ʻia ka hoʻāʻo ʻana no ka hoʻokaʻawale ʻana i ke kila kalapona, ke kila kila a me ke kila mea hana, akā he mea liʻiliʻi ia i ka hoʻokaʻawale ʻana i ke kila kila. Hiki i kēia ʻano hoʻāʻo spark ke kōkua i nā mea hoʻohana ʻike e hoʻokaʻawale i ke kila kila i ʻehā mau ʻāpana nui, akā ʻaʻole maʻalahi ke hoʻokaʻawale ma waena o nā pae kila like ʻole.

ʻO ke ʻano o kēia mau ʻano ʻehā o nā mīkini kila kuhili ʻole penei:

Papa A: 302, 303, 316 kila, e hana ana i nā ʻulaʻula pōkole ʻulaʻula me nā ʻōpala.

Papa B: 308, 309, 310 a me 446 kila, e hana ana i ka liʻiliʻi liʻiliʻi pōkole ʻulaʻula ʻeleʻele me nā ʻōpala.

Papa C: 410, 414, 416, 430 a me 431 kila, e hana ana i na lama keokeo loloa me kekahi mau laau.

Papa D: 420, 420F a me 440A, B, C, F, e hana ana i nā ʻōlinolino ʻālohilohi me nā ʻōlinolino maopopo a i ʻole nā ​​ʻulaʻula keʻokeʻo lōʻihi.

10. Ma o ka ʻike waika hydrochloric

Hiki i kēia ʻano ʻike ke hoʻokaʻawale i ka 403, 410, 416, 420 ke kila kila me ka haʻahaʻa chromium haʻahaʻa mai 430, 431, 440, 446 kila kila me ka maʻi chromium kiʻekiʻe.

E hoʻoheheʻe i ka nui like o nā ʻoki laʻana i loko o ka waika hydrochloric solution me ka nui o 50% no kahi o ʻekolu mau minuke, a e hoʻohālikelike i ka ikaika kala o ka hopena. ʻO ke kila me kahi kiʻekiʻe o ka chromium ʻoi aku ka ʻeleʻele ʻōmaʻomaʻo.
