Tus txheej txheem tswj hwm: EN 10083 / 1-1991
Raws li Suav hom: 40Cr
Raws li Japanese hom: SCr440
Raws li US hom: 5140
Raws li UK hom: 530A40530M40
Yam ntxwv thiab Scope of Application:
41Cr4 (1.7035) yog cov feem ntau siv alloy structural steel, muaj zog tensile ntau zog, yield zog, thiab hardenability tshaj No. 40 steel, tab sis txwv weldability thiab ib tug nyiam tsim cov kab nrib pleb. 41Cr4 yog siv rau qhov tseem ceeb quenched thiab tempered qhov chaw, xws li qhov chaw ua hauj lwm nyob rau hauv alternating loads, qhov nruab nrab speeds thiab loads. Tom qab deg quenching, nws tuaj yeem siv rau qhov chaw uas muaj kev thauj khoom siab thiab hnav tsis muaj kev cuam tshuam tseem ceeb, xws li lub zog, lub tes tsho, ncej, crankshafts, thiab pins.

1045 Carbon Steel Khoom

AISI1045 yog ib qho uas feem ntau siv nruab nrab carbon steel siv hauv kev tsim cov khoom siv xws li cov khoom siv kho tshuab, cov kabmob, thiab cov khoom siv tsheb. Nws cov tshuaj muaj pes tsawg leeg yog carbon 0.43-0.50%, manganese 0.60-0.90%, sulfur mus txog 0.050%, thiab phosphorus nce rau 0.040%. Nws cov khoom muaj xws li lub zog tawm ntawm 345 MPa, lub zog tensile ntawm 630 MPa, thiab elongation ntawm 20%. Nws lub xeev kho cua sov yog normalized lossis normalized + tempered, uas tuaj yeem txhim kho nws lub zog thiab hardness. AISI1045 muaj kev ua haujlwm zoo thiab kev ua haujlwm vuam, thiab yog cov khoom siv feem ntau siv.
