ASTM A514 Gulu T zitsulo mbale

ASTM A514 imagwiritsidwa ntchito kwambiri ngati chitsulo chokhazikika pamakina ndi makina akulu olemetsa.

A514 ndi mtundu wina wa chitsulo champhamvu kwambiri, chomwe chimazimitsidwa ndi chitsulo chosungunuka, chokhala ndi mphamvu zokolola za 100,000 psi (100 ksi kapena pafupifupi 700 MPa). Dzina lodziwika ndi dzina la ArcelorMittal ndi T-1. A514 imagwiritsidwa ntchito ngati chitsulo chomanga pomanga. A517 ndi aloyi yogwirizana kwambiri yomwe imagwiritsidwa ntchito popanga zotengera zamphamvu kwambiri.

Uwu ndi mulingo wokhazikitsidwa ndi bungwe lodziyimira pawokha la ASTM International, mabungwe odziyimira pawokha omwe amakhazikitsa miyezo yaukadaulo pazinthu, zinthu, machitidwe, ndi ntchito.

A514
Mphamvu zokolola za A514 alloys zimatchulidwa kuti ndi osachepera 100 ksi (689 MPa) chifukwa cha makulidwe mpaka mainchesi 2.5 (63.5 mm) wandiweyani, ndi osachepera 110 ksi (758 MPa) mphamvu yomaliza yokhazikika, yokhala ndi mawonekedwe omaliza a 110–130 ksi (758–896 MPa). Mimbale yochokera pa mainchesi 2.5 mpaka 6.0 (63.5 mpaka 152.4 mm) yokhuthala yafotokoza mphamvu za 90 ksi (621 MPa) (zokolola) ndi 100–130 ksi (689–896 MPa) (zomaliza).

A517
Chitsulo cha A517 chili ndi mphamvu yokwanira yokolola, koma yokwera pang'ono yodziwika bwino kwambiri ya 115-135 ksi (793-931 MPa) ya makulidwe mpaka mainchesi 2.5 (63.5 mm) ndi 105-135 ksi (724-931 MPa) makulidwe a 2.5 mpaka 6.0 mainchesi (63.5 mpaka 152.4 mm).

Kugwiritsa ntchito
Zitsulo za A514 zimagwiritsidwa ntchito pomwe chitsulo chowotcherera, chosinthika, champhamvu kwambiri chimafunikira kuti chichepetse kulemera kapena kukwaniritsa zofunika kwambiri zamphamvu. Nthawi zambiri amagwiritsidwa ntchito ngati chitsulo chomangira pomanga nyumba, ma cranes, kapena makina ena akulu omwe amathandiza katundu wambiri.

Kuphatikiza apo, zitsulo za A514 zimatchulidwa ndi miyezo yankhondo (ETL 18-11) kuti zigwiritsidwe ntchito ngati zida zazing'ono zowombera ndi mbale zopotoka.

Mechnical katundu wa A514GrT aloyi zitsulo:

Chemical kapangidwe kwa A514GrT aloyi zitsulo (Kutentha Analysis Max%)

Zofunikira Zaukadaulo & Ntchito Zowonjezera:

• Kuthamanga kwakukulu
• Mayeso okhudza kutentha kochepa
• Simulated post-weld heat treatment (PWHT)
• Satifiketi yoyeserera ya Orginal Mill yoperekedwa pansi pa EN 10204 FORMAT 3.1/3.2
• Pamene zitsulo zachitsulo zimatchulidwa A709 Gr36, zomwe zili Cu≥0.20%
• Kuwombera ndi Kupenta, Kudula ndi kuwotcherera malinga ndi zofuna za wogwiritsa ntchito
• Makulidwe olemera ( mainchesi atatu kapena kukhuthala) amapezeka m'malo ambiri ogawa a Leeco Steel.
• Imapezeka m'makalasi okhazikika: 36, 50 ndi 50W.
• Ikupezeka m'makalasi ochita bwino kwambiri: HPS 50W ndi HPS 70W.
• Makasitomala atha kufotokoza magiredi a A709 kuti akwaniritse zoyeserera za Charpy pamagawo ndi nyengo.
