Setšoantšo sa SM520tšepe platehaholo-holo e entsoe ka carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sebabole (S), chromium (Cr), nickel (Ni), molybdenum (Mo) le likarolo tse ling. Har'a bona, k'habone ke karolo ea skeleton ea tšepe, e ka ntlafatsang matla le ho tiea ha tšepe, empa hape e fokotsa polasetiki le ho tiea ha tšepe. Silicon le manganese li ka etsa litharollo tse tiileng ka k'habone, li eketsa matla le ho tiea ha tšepe ha li ntse li boloka polasetiki le ho tiea ha eona. Phosphorus le sebabole li ka ntlafatsa ts'ebetso ea tšepe ea tšepe le ho ntlafatsa ho hanyetsa ho bola ha tšepe. Chromium le nickel li ntlafatsa ho hanyetsa ho bola ha tšepe, haholo-holo libakeng tsa leoatle. Molybdenum e ka ntlafatsa lithollo tsa tšepe le ho ntlafatsa ts'ebetso ea tšepe ka kakaretso. Hoa lokela ho hlokomeloa hore litšobotsi tsa sebopeho ke lintlha tsa bohlokoa tse amang thepa ea mochine le ho hanyetsa kutu eaLetlapa la tšepe la SM520s, kahoo li hloka ho lokisoa ho latela ts'ebeliso e fapaneng le maemo a tikoloho ho fihlela litlhoko tsa maemo a fapaneng a ts'ebeliso.
Letlapa la tšepe la SM520e na le matla a ho hlahisa lihlahisoa tse ngata le matla a tsitsitseng 'me e ka finyella litlhoko tsa mehaho e meholo e jereng mojaro.
SM520 sebopeho sa lik'hemik'hale:
C: ≤0.2 Si: ≤0.55 Mn: ≤1.65 P: ≤0.035 S: ≤0.035
Mechine ea SM520:
Matla a ho kotula: ≥365MPa Matla a Tensile: 520-640MPa Elongation: ≥19% 0 degree matla a tšusumetso: ≥47
Letlapa la tšepe la SM520 le na le matla a matle, le khona ho mamella meroalo e meholo, 'me ha le rate ho robeha habonolo.
SM520tšepe platee sebelisoa haholo bakeng sa Marokho, likereene, mechini ea merafo, likepe, liteishene tsa motlakase, makoloi, litanka tsa polokelo ea peterole, lik'hontheinara le lintho tse ling tse cheselitsoeng tse jereng meroalo e matla.
Plate ea tšepe ea SM520 e na le ts'ebetso e ntle ea ts'ebetso 'me e ka sebelisoa bakeng sa ho seha, ho kobeha, ho cheka le lits'ebetso tse ling tsa ho lokisa.
Letlapa la tšepe la SM520 le na le ts'ebetso e ntle ea ho tjheseletsa mme le ka fihlela litlhoko tsa lits'ebetso tse fapaneng tsa welding
Letlapa la tšepe la SM520 le na le khanyetso e ntle ea kutu 'me le khona ho mamella ho bola libakeng tse fapaneng tse thata ka nako e telele. Ho hanyetsa kutu ke bokhoni ba thepa ea ho hanela kutu sebakeng se senyang mme ke sesupo sa bohlokoa sa bophelo ba ts'ebeletso ea thepa. Letlapa la tšepe la SM520 le bonts'a khanyetso e ntle ea kutu libakeng tse senyang joalo ka tikoloho ea leoatle le tikoloho ea indasteri, 'me e ka lelefatsa bophelo ba eona ba ts'ebeletso ka nepo.
