ASTM A516 vs A36, A572, Q355: Kusarudza Pureti Yesimbi Yakakodzera Yekuvaka Kwemazuva Ano

Sezvo indasitiri yekuvaka ichiramba ichichinja, kusarudza ndiro yesimbi yakakodzera yemapurojekiti ekuvaka kwakakosha kupfuura kare.ASTM A516 ndiro yesimbisimbi yekabhoni inoshandiswa mumidziyo yekumanikidza, iri kuramba ichinyanya kutariswa mumabasa ekuvaka nekuda kwesimba rayo guru, kugona kwayo kupinza zvakanaka, uye kushanda kwayo pakupisa kwakaderera. Asi inoenzaniswa sei nedzimwe simbi dzinowanzo shandiswa sesimbi dzekuvaka dzakadai seMaplate esimbi eASTM A36 , Maplate esimbi eASTM A572, uye machira esimbi eQ355 ekuChina?

Kushanda Kwemakanika Uye Simba

ASTM A516 (Magiredhi 60-70) inopa simba rekukura kwe260–290 MPa uye simba rekudhonza rinosvika 550 MPa, pamwe chete nekusimba kwakanyanya kwekupisa kunosvika -45°C. Kana tichienzanisa:

ASTM A36– Simba remushonga 250 MPa, kudhonza 400–550 MPa, kushanda zvakanaka pakupisa kwakaderera.

ASTM A572 (Gr.50)– Goho re345 MPa, kudhonza 450–620 MPa, kugona kusundira zvakanaka uye kusimba kwekupisa kwakaderera.

Q355– Inobereka 355 MPa, inodhonza 470–630 MPa, inoshandiswa zvakanyanya mumapurojekiti ekuvaka ekuChina nekuda kwesimba rayo guru uye kugara kwenguva refu.

Izvi zvinoita kuti A516 ive yakakodzera matanda anorema, mabhiriji ekupedzisira, uye zvikamu zvemaumbirwo munzvimbo dzinotonhora.

Maitiro Ekuvaka Akajairika

Simbi Mashandisirwo
ASTM A516 Maplate anotakura mutoro, zvikamu zvebhiriji, zvivakwa zvinodziya zvishoma, zvinhu zvinotsigira kumanikidzwa
A36 Matanda akajairika, makoramu, uye mafuremu ekutanga ekuvaka
A572 Matanda ekuvaka marefu, mafekitori emaindasitiri, mabhiriji, zvivakwa zvisingapindi mamiriro ekunze
Q355 Zvivako zvemaindasitiri, matura ekuchengetera zvinhu, mabhiriji, mapurati anotakurwa nemitoro

Kugadzirisa uye Kuchinjika

Kugona kupinza uye kugadzira zvakanaka kweA516 kunoita kuti ikwanise kuumbwa kuita maplate akakora anotakura mutoro, majoini akasungirirwa, uye zvikamu zvechimiro zvakasimbiswa. A36 iri nyore kugadzirisa asi haina kukodzera kushandiswa mukutakura mutoro unorema kana kwenguva refu. A572 neQ355 dzinopa simba rakawanda asi dzinoda kudzora kupinza nekungwarira kwezvikamu zvakakora.

Kusarudza Simbi Yakakodzera

Pamapurojekiti ekuvaka emazuva ano, mainjiniya anowedzera kufunga nezveASTM A516 kana zvikamu zvechivakwa zvichida simba uye kushanda kwakaderera. Kune mapuratifomu ekuvaka akajairika, A36 ichiri sarudzo inodhura zvishoma. Panguva iyi, A572 neQ355 zvinofarirwa kune zvivakwa zvirefu, mabhiriji, uye zvivakwa zvemaindasitiri uko kusimba kwakasimba uye kugara kwenguva refu kwakakosha.

Sezvo mitemo yekuvaka ichikwira pasi rose, kunzwisisa mutsauko uri pakati pemhando dzesimbi kwakakosha kuti pave nekuchengetedzeka, mutengo, uye mashandiro akanaka mune chero chirongwa.
