Pae Porowhita 304 Kowiri tira

Ko te kowiri tira 304, he porowhita maeneene, e pā ana ki te mata maeneene, ka tukatukahia mā te huri, te tihore, te oro matao rānei; he maha ngā whakamahinga i roto i ngā momo matū, kai, kakahu me ētahi atu taputapu miihini me ētahi atu kaupapa whakapaipai. Ko te mea e kiia nei ko te kowiri tira 304 pango porowhita, ko te tokotoko kowiri tira 304 rānei (tokotoko pango) e pā ana ki te maitai porowhita he pango, he taratara te mata, ka hurihia tika ki te wera, ka hangaia, ka whakamahanahia rānei, ka whakamahanahia rānei, kāore e tukatukahia te paparanga waikura i runga i te mata.

304: 18-8 te maitai kore waikura, ko te tohu tohutoro GB ko 0Cr18Ni9; Ko te paerewa whakatinanatanga o te paerewa Amerikana: ASTM A276.

GB: C≤0.07; Si≤1.0; Mn≤2.0; P≤0.045; S≤0.03; Ni: 8.0-11.0; Kr: 17.0-19.0

ASTM: C≤0.08; Si≤1.0; Mn≤2.0; P≤0.045; S≤0.03; Ni:8.0-11.0; Kr:18.0-20.0

Ko te maitai kore waikura 304 te maitai kore waikura chromium-nickel e whakamahia whānuitia ana, he pai te ātete ki te waikura, te ātete ki te wera, te kaha ki te pāmahana iti me ngā āhuatanga miihini. He ātete ki te waikura i te hau. Mena he hau ahumahi, he wāhi poke rawa rānei, me horoi wawe kia kore ai e waikura. [1]

E ai ki te tukanga whakaputa, ka wehea te maitai porowhita kowiri tira 304 ki ngā momo e toru: te hurihuri wera, te hanga me te kume makariri. Ko te whakatakotoranga o te pae porowhita kowiri tira 304 hurihuri wera ko te 5.5-130 mm. I roto i ēnei: ​​5.5-25mm iti 304 kowiri tira porowhita te nuinga o te wā e tukuna ana i roto i ngā rīpene tika, e whakamahia ana hei pae maitai, hei pūtu me ngā wāhanga miihini; i roto rānei i te āhua porowhita, hei hua haurua-oti mō te tukatuka anō i muri mai. Ko te maitai porowhita kowiri tira 304 nui ake i te 25 mm ka whakamahia te nuinga ki te hanga wāhanga miihini, ki te poka rānei i ngā pire ngongo maitai kore hononga. [2]

Te tātaitanga ariā mō te taumaha porowhita o te maitai kore waikura 304:

Taumaha mō ia mita (kg) = diameter * diameter * 0.00623
