I-ASTM A514 yeBanga T ipleyiti yentsimbi

I-ASTM A514 isetyenziswa ngokuqhelekileyo njengentsimbi yesakhiwo kwii-cranes kunye noomatshini abakhulu bomthwalo onzima.

I-A514 luhlobo oluthile lwensimbi ephezulu yamandla, ecinywa kunye nentsimbi ye-alloy epholileyo, enegunya lokuvelisa i-100,000 psi (100 ksi okanye malunga ne-700 MPa). Igama lentengiso ye-ArcelorMittal ngu-T-1. I-A514 isetyenziswe ngokukodwa njengentsimbi yesakhiwo sokwakhiwa kwesakhiwo. I-A517 yi-alloy ehambelana ngokusondeleyo esetyenziselwa ukuveliswa kweenqanawa zoxinzelelo oluphezulu.

Lo ngumgangatho obekwe yimigangatho yentlangano ye-ASTM International, imibutho yophuhliso lwemigangatho yokuzithandela ebeka imigangatho yobugcisa kwizinto, iimveliso, iinkqubo kunye neenkonzo.

A514
Amandla esivuno se-tensile ye-A514 alloys icaciswa njenge-100 ksi ubuncinane (689 MPa) yobunzima obufikelela kwi-2.5 intshi (63.5 mm) ipleyiti etyebileyo, kunye nobuncinci be-110 ksi (758 MPa) amandla okugqibela okuqina, kunye noluhlu oluchaziweyo lokugqibela. 110–130 ksi (758–896 MPa). Amacwecwe ukusuka kwi-2.5 ukuya kwi-intshi ye-6.0 (63.5 ukuya kwi-152.4 mm) ubukhulu acacisiwe amandla angama-90 ksi (621 MPa) (isivuno) kunye ne-100–130 ksi (689–896 MPa) (eyokugqibela).

A517
Intsimbi ye-A517 inamandla alinganayo e-tensile yesivuno, kodwa ngaphezulu kancinci kukhankanyiwe amandla okugqibela e-115–135 ksi (793–931 MPa) ngokutyeba ukuya kuma-intshi ezi-2.5 (63.5 mm) kunye ne-105–135 ksi (724–931 MPa) kubunzima obuyi-2.5 ukuya kuma-intshi. 6.0 intshi (63.5 ukuba 152.4 mm).

Ukusetyenziswa
Iintsimbi ze-A514 zisetyenziswa apho kufuneka intsimbi edityanisiweyo, enokusetyenzwa, iqine kakhulu ukuze kugcinwe ubunzima okanye ukuhlangabezana neemfuno zamandla okugqibela. Ngokuqhelekileyo isetyenziswa njengentsimbi yesakhiwo ekwakhiweni kwesakhiwo, iikhreyini, okanye ezinye iimatshini ezinkulu ezixhasa imithwalo ephezulu.

Ukongezelela, iintsimbi ze-A514 zichazwe yimigangatho yemikhosi (ETL 18-11) ukuze zisetyenziswe njengezixhobo ezincinci zokudubula ii-baffles kunye namacwecwe e-deflector.

Ipropathi yobuchwephesha yentsimbi yentsimbi ye-A514GrT:

Ukwakhiwa kweekhemikhali zentsimbi ye-A514GrT ye-alloy (uHlalutyo lobushushu uBuninzi%)

IiMfuno zobuGcisa kunye neeNkonzo ezongezelelweyo:

• Uvavanyo loxinzelelo oluphezulu
• Uvavanyo oluchaphazela ubushushu obuphantsi
• Unyango olulinganisiweyo lobushushu lwasemva kwe-welded (PWHT)
• Sikhutshwe isatifikethi sovavanyo lwe-Orginal Mill phantsi kwe-EN 10204 FORMAT 3.1/3.2
• Xa intsimbi ye-cooper ichazwe kwi-A709 Gr36, umxholo we-Cu≥0.20%
• Ukudubula nokupeyinta, ukusika kunye nokuwelda ngokwemfuno zabasebenzisi bokugqibela
• Ubungqingqwa obunzima (ii-intshi ezi-3 okanye ngaphezulu) bufumaneka kuninzi lwamaziko osasazo eLeeco Steel.
• Ifumaneka kumabakala aqhelekileyo: 36, 50 kunye ne-50W.
• Ifumaneka kumabakala aphezulu okusebenza: i-HPS 50W kunye ne-HPS 70W.
• Abathengi banokuchaza amabakala angama-A709 ukuhlangabezana neemfuno zovavanyo lweCharpy kwimimandla ethile kunye nemozulu.
