AISI SAE 4130 4140 4145H Steel Round Bar Hollow Rod
Likaroloana
4130 4135 4140 4145H litšepe tsa tšepe ke tšepe e tlaase ea carbon alloy.Ke tsa alloy ea Chrome-Molly e nang le chromium le molybdenum e le lisebelisoa tse matlafatsang.
4130 round steel bar e na le bokhoni bo botle ba ho sebetsa, deformation e nyane ea ts'ebetso, le khanyetso e ntle ea mokhathala.Ke karolo ea tšepe ea matla a mahareng ho isa ho a phahameng.Ka mor'a phekolo ea mocheso, 4140 e na le matla a matle le thepa e feletseng ea mochine, bokhoni bo botle ba ts'ebetso, le chai e ngata.Mocheso oa tšebeletso ke likhato tse 427 tsa Celsius.
4140 e na le matla a phahameng, bokhoni bo thata, ho tiea, le deformation nakong ea ho tima.E na le matla a phahameng a ho hahaba le matla a ho mamella mocheso o phahameng.E sebelisetsoa ho etsa li-forging tse hlokang matla a phahameng le likarolo tse kholoanyane tse tingoeng le tse halefileng ho feta tšepe ea 4135, joalo ka likere tse kholo bakeng sa ho tsamaisa li-locomotive traction, booster transmission gears, li-axle tse ka morao, lithupa tse hokelang le likotoana tsa selemo tse imetsoeng haholo.
