Ipuleti lensimbi ye-ASTM A514 yeBanga T

I-ASTM A514 isetshenziswa kakhulu njengensimbi yesakhiwo kuma-cranes nasemishinini emikhulu ethwala kanzima.

I-A514 iwuhlobo oluthile lwensimbi enamandla amakhulu, ecinywa futhi eqinile i-alloy steel, enamandla okukhiqiza angu-100,000 psi (100 ksi noma cishe 700 MPa). Igama eliphawulwe yi-ArcelorMittal ngu-T-1. I-A514 isetshenziswa ngokuyinhloko njengensimbi yesakhiwo yokwakha. I-A517 iyingxubevange ehlobene eduze esetshenziselwa ukukhiqizwa kwemikhumbi yokucindezela okunamandla.

Leli izinga elibekwe yinhlangano yamazinga i-ASTM International, izinhlangano zokuzithandela zokuthuthukisa amazinga ezibeka izindinganiso zobuchwepheshe zezinto zokwakha, imikhiqizo, amasistimu, namasevisi.

A514
Amandla okukhiqiza aqinile we-A514 alloys acaciswa okungenani njenge-100 ksi (689 MPa) yogqinsi olungafika ku-2.5 amayintshi (63.5 mm) ipuleti eliwugqinsi, futhi okungenani 110 ksi (758 MPa) amandla okugcina aqinile, anobubanzi obukhethekile obucacisiwe. 110–130 ksi (758–896 MPa). Amapuleti asuka ku-2.5 kuya ku-6.0 amayintshi (63.5 kuya ku-152.4 mm) awugqinsi acacise amandla angu-90 ksi (621 MPa) (isivuno) kanye no-100–130 ksi (689–896 MPa) (owokugcina).

A517
Insimbi ye-A517 inamandla alinganayo okukhiqiza amandla, kodwa ashiwo phezulu kancane aqinile angu-115–135 ksi (793–931 MPa) ngogqinsi olungafika kumayintshi angu-2.5 (63.5 mm) no-105–135 ksi (724–931 MPa) ngogqinsi olufika ku-2.5 kuya ku- 6.0 amayintshi (63.5 kuya ku-152.4 mm).

Ukusetshenziswa
Izinsimbi ze-A514 zisetshenziswa lapho kudingeka khona insimbi eshiselwayo, eshintshwayo, enamandla kakhulu ukuze kongiwe isisindo noma kuhlangatshezwane nezidingo zamandla ekugcineni. Ngokuvamile isetshenziswa njengensimbi yesakhiwo ekwakhiweni kwesakhiwo, ama-cranes, noma eminye imishini emikhulu esekela imithwalo ephezulu.

Ngaphezu kwalokho, izinsimbi ze-A514 zicaciswa ngamazinga ezempi (ETL 18-11) ukuze zisetshenziswe njengama-baffles ahlukahlukene okudubula izingalo namapuleti okuphambukisa.

Impahla yemishini yensimbi ye-A514GrT ingxubevange:

Ukwakheka kwamakhemikhali kwensimbi ye-A514GrT ingxubevange (Ukuhlaziywa Kokushisa Okuphezulu%)

Izidingo Zobuchwepheshe Nezinsizakalo Ezengeziwe:

• Ukuhlolwa kwengcindezi ephezulu
• Ukuhlolwa okunomthelela kwezinga lokushisa eliphansi
• Ukwelashwa kokushisa kwangemuva kwe-welded (PWHT)
• Isitifiketi sokuhlola se-Orginal Mill esikhishwe ngaphansi kwe-EN 10204 FORMAT 3.1/3.2
• Lapho i-cooper steel icaciswa ku-A709 Gr36, okuqukethwe ngu-Cu≥0.20%
• Ukudubula nokupenda, Ukusika kanye nokushisela njengezidingo zomsebenzisi ngamunye
• Ugqinsi olusindayo (amayintshi angu-3 noma ugqinsi) olutholakala ezikhungweni eziningi zokusabalalisa ze-Leeco Steel.
• Itholakala kumabanga ajwayelekile: 36, 50 kanye no-50W.
• Itholakala kumabanga asebenza kahle kakhulu: i-HPS 50W ne-HPS 70W.
• Amakhasimende angacacisa amamaki angu-A709 ukuze ahlangabezane nemfuneko yokuhlolwa kwe-Charpy yezindawo ezithile nesimo sezulu.
