aikin da ake bukata
(1) Babban ƙarfi: gabaɗaya, ƙarfin yawan amfanin sa yana sama da 300MPa.
(2) Babban ƙarfi: elongation da ake buƙata shine 15% ~ 20%, kuma tasirin tasiri a cikin zafin jiki ya fi 600kJ / m ~ 800kJ / m.Don manyan abubuwan da aka welded, ana buƙatar taurin karaya kuma.
(3) Good waldi yi da sanyi kafa yi.
(4) Low sanyi gaggautsa zafin jiki.
(5) Kyakkyawan juriya na lalata.
3. Haɗin kai halaye na galvanized bututu
(1) Low carbon: saboda babban buƙatun don tauri, weldability da sanyi kafa yi, da carbon abun ciki ba zai wuce 0.20%.
(2) Manganese tushen gami an ƙara.
(3) Ƙara niobium, titanium ko vanadium: ƙaramin niobium, titanium ko vanadium yana samar da carbide mai kyau ko carbonitride a cikin karfe, wanda zai dace don samun hatsi mai kyau na ferrite da inganta ƙarfi da taurin karfe.Bugu da ƙari, ƙara ƙaramin adadin jan karfe (≤ 0.4%) da phosphorus (kimanin 0.1%) na iya inganta juriya na lalata.Ƙara ƙaramin adadin abubuwan da ba kasafai ba na duniya na iya cire sulfur da iskar gas, tsarkake ƙarfe, da haɓaka tauri da aiki.
