Chithunzi cha S355JOHndi muyezo wakuthupi womwe ndi wazitsulo zotsika za alloy structural ndipo umagwiritsidwa ntchito makamaka popanga zigawo za dzenje zozizira komanso zotentha.Mulingo wachitsulo uwu umachokera ku mulingo wa EN 10219 waku Europe ndipo ndiwoyenera kwambiri popanga zigawo za dzenje zozizira.
Chithunzi cha S355JOHangagwiritsidwe ntchito popanga mitundu yosiyanasiyana ya machubu, kuphatikizapo machubu ozungulira (SSAW), machubu opanda msoko (SMLS), ndi machubu owongoka msoko (RW kapena LSAW).
Chithunzi cha S355JOH
"S" amaimira chitsulo structural;"355" imayimira zinthu zomwe zimakhala ndi mphamvu zochepa zokolola za 355 MPa, zomwe zimatsimikizira kukhazikika kwadongosolo;"
J0H" imatanthawuza gawo la dzenje lozizira lokhala ndi mphamvu ya 27 J pamayeso a kutentha kwa 0°C.
S355JOH mankhwala opangidwa
Mpweya (C): 0.20% max.
Silicon (Si): 0.55% max.
Manganese (Mn): pazipita 1.60%
Phosphorasi (P): 0.035% max.
Sulfure (S): 0.035% max.
Nayitrojeni (N): 0.009% max.
Aluminiyamu (Al): 0.020% osachepera (chofunikirachi sichigwira ntchito ngati chitsulo chili ndi zinthu zokwanira zomangira nayitrogeni)
Chonde dziwani kuti zida za mankhwala zitha kusiyanasiyana kutengera wopanga komanso mawonekedwe ake.Kuphatikiza apo, zinthu zina zophatikizika, monga vanadium, faifi tambala, mkuwa, ndi zina zotere, zitha kuwonjezeredwa panthawi yopanga kuti zithandizire kukulitsa mawonekedwe achitsulo, koma kuchuluka ndi mtundu wa zinthuzi zomwe zawonjezeredwa ziyenera kukhala molingana ndi miyezo yoyenera.
Zithunzi za S355JOH
Mphamvu zochepa zokolola zosachepera 355 MPa;
Mphamvu zolimba za 510 MPa mpaka 680 MPa;
Kutalika kwake kochepa nthawi zambiri kumafunika kukhala oposa 20 peresenti;
Zindikirani kuti kukulitsa kumatha kukhudzidwa ndi kukula kwachitsanzo, mawonekedwe, ndi miyeso yoyeserera, chifukwa chake pamakina apadera aukadaulo, pangakhale kofunikira kunena zatsatanetsatane kapena kuwunika ndi omwe amapereka zinthu kuti mupeze zolondola.
S355JOH Makulidwe ndi Kulekerera
Kulekerera kwa Diameter Yakunja (D)
Kwa ma diameter akunja osapitilira 168.3mm, kulolerana ndi ± 1% kapena ± 0.5mm, chomwe chili chachikulu.
Kwa awiri akunja akulu kuposa 168.3mm, kulolerana ndi ± 1%.
Kulemera Kwakhoma (T) Kulekerera
Khoma makulidwe kulolerana kutengera kukula yeniyeni ndi khoma makulidwe kalasi (monga momwe tawonetsera pa tebulo), kawirikawiri mu ± 10% kapena kuposa, kulamulira yeniyeni ntchito makulidwe khoma, angafunike dongosolo lapadera.
Kulekerera Utali
The kulolerana kwa muyezo kutalika (L) ndi -0/+50mm.
Kwa kutalika kokhazikika, kulolerana kumakhala ± 50mm.
utali weniweni kapena utali weniweni ukhoza kukhala ndi zofunikira zolimba zololera, zomwe ziyenera kutsimikiziridwa pokambirana ndi wopanga panthawi yoyitanitsa.
Kulekerera kowonjezera kwa Magawo a Square ndi Rectangular
Magawo am'bwalo ndi amakona anayi ali ndi kulekerera kozungulira kwa ngodya ya 2T, pomwe T ndi makulidwe a khoma.
Kulekerera Kusiyana kwa Diagonal
Ndiko kuti, kusiyana kwakukulu kwa kusiyana pakati pa kutalika kwa magawo awiri a diagonal a magawo apakati ndi amakona anayi, nthawi zambiri sikuposa 0,8% ya kutalika kwake.
Kulekerera Kumanja Kongolerani ndi Digiri Yopotoza
Kulekerera kwa kuwongoka (ie, verticality of a part) ndi kupindika (ie, kusalala kwa gawo) zimafotokozedwanso mwatsatanetsatane muyeso kuti zitsimikizire kulondola kwapangidwe ndi mawonekedwe onse.
Ndi chifukwa cha kudzipatulira kwathu kuti tichite bwino kwambiri pakupanga chilichonse, kuphatikizapo chidziwitso chathu chakuya ndi chidziwitso chathu mumakampani omwe timatha kukhala otsogola pakupanga.Chithunzi cha S355JOHchitoliro chachitsulo.
Timamvetsetsa kuti projekiti iliyonse ili ndi zofunikira zolimba pakuchita kwazinthu, chifukwa chake, sitimangopereka zinthu zokha komanso timapereka mayankho athunthu kwa makasitomala athu.Ngati muli ndi zosowa za katundu wathu kapena ntchito kapena muli ndi mafunso, chonde omasuka kulankhula nafe.Gulu lathu lili ndi akatswiri odziwa zambiri omwe ali okonzeka kukupatsirani zambiri zamalonda, zothetsera makonda, komanso chithandizo chaukadaulo.
