Iindaba

imfuneko yokusebenza
(1) Amandla aphezulu: ngokubanzi, amandla ayo okuvelisa angaphezulu kwe-300MPa.
(2) Ukuqina okuphezulu: ubude obufunekayo yi-15% ~ 20%, kunye nokuqina kwempembelelo kwiqondo lokushisa elikhulu kune-600kJ / m ~ 800kJ / m.Kumalungu amakhulu adityanisiweyo, ukuqina kokwaphuka okuphezulu kuyafuneka.
(3) Ukusebenza kakuhle kwe-welding kunye nokusebenza okubandayo.
(4) Iqondo lobushushu eliphantsi elibandayo elibandayo.
(5) Ukumelana nokugqwesa okulungileyo.
3. Iimpawu zokuqulunqa umbhobho we-galvanized
(1) Ikhabhoni ephantsi: ngenxa yeemfuno eziphezulu zokuqina, i-weldability kunye nokusebenza okubandayo, umxholo wekhabhoni awuyi kudlula i-0.20%.
(2) I-Manganese esekelwe kwi-alloy element yongezwa.
(3) Ukongezwa kwe-niobium, i-titanium okanye i-vanadium: inani elincinci le-niobium, i-titanium okanye i-vanadium yenza i-carbide efanelekileyo okanye i-carbonitride kwintsimbi, ekulungele ukufumana iinkozo ezintle ze-ferrite kunye nokuphucula amandla kunye nokuqina kwentsimbi.Ukongezelela, ukongeza inani elincinci lobhedu (≤ 0.4%) kunye ne-phosphorus (malunga ne-0.1%) inokuphucula ukuxhathisa ukubola.Ukongeza inani elincinci lezinto ezinqabileyo zomhlaba kunokususa isulfure kunye negesi, ukucoca intsimbi, kunye nokuphucula ukuqina kunye nokusebenza kwenkqubo.
