16MnCr5 Alloy Steel Forging Gears nwere CNC Machining

Okwu mmeghe

16MnCr5 alloy steel, igwe anaghị agba nchara dị elu sitere na Germany, bụ onye nnọchi anya igwe eji arụ ọrụ dị elu. Na China, a na-akpọkarị ya 16CrMnH (dị ka ọkọlọtọ GB/T 5216-2004 si dị). Ihe a ejirila ebe dị n'ọhịa nke njedebe dị eluihe nkedo gian'ichepụta n'ihi na ya magburu onwe carburizing arụmọrụ, magburu onwe hardenability na ezi machinability. Mgbe carburizing na quenching ọgwụgwọ, elu ike nke 16MnCr5alloy ígwè forgingsna-emewanyewanyewanye nke ọma na nguzogide iyi na-abawanye nke ukwuu. Ọ bụ ezigbo nhọrọ maka imepụta akụkụ ndị na-ebu ibu dị arọ na esemokwu ugboro ugboro.

Ngwakọta kemịkalụ na microstructure

Ejirila nke ọma kemịkalụ kemịkalụ nke 16MnCr5 alloy steel iji hụ na akụrụngwa ya dị mma:
C: 0.14% ~ 0.19%, na-enye ike na ike dị mkpa maka ígwè.
Si: ≤0.40%, na-enyere aka melite nkwụsi ike nke okpomọkụ na nguzogide oxidation nke ígwè.
Mn: 1.00% ~ 1.30%, na-eme ka ike na ike nke ígwè dịkwuo elu.
Cr: 0.80% ~ 1.10%, budata mma nguzogide corrosion ma na-eyi nguzogide ígwè.
S: ≤0.035%, na-achịkwa thermal brittleness nke ígwè.
P: ≤0.035%, na-eme ka ike na iguzogide corrosion ikuku nke ígwè dị mma.

Ngwa igwe

16MnCr5 alloy ígwè nwere ọmarịcha ihe eji arụ ọrụ ma nwee ike gboo mkpa nke ngwa ụlọ ọrụ siri ike:
Ike ike (MPa): 880-1180, na-eme ka nkwụsi ike nke akụkụ ahụ mgbe a na-etinye ya n'ahụ ike.
Ike mkpụrụ nke ọnọdụ (MPa): na-adịkarị gburugburu 635 (uru a kapịrị ọnụ nwere ike ịdịgasị iche dabere na usoro ọgwụgwọ okpomọkụ), na-ahụ na ike ibu ihe ahụ tupu m ekweta.
Elongation (%): 9, na-egosi na ihe ahụ nwere ezigbo plasticity na ọ dịghị mfe imebi mgbe etinyere ya n'ike.
Mbelata nke ngalaba (%): 57 (ma ọ bụ 35, dabere na ọnọdụ nnwale na nha ụdị), na-egosipụta ikike nnabata ike nke ihe ahụ tupu agbaji.
Uru siri ike mmetụta (J/cm²): 34, na-egosipụta ike ihe ahụ mgbe etinyere ya.
Isi ike: ≤297 HB, na-enye ezigbo ntọala maka ọgwụgwọ carburizing na nkwụsịtụ na-esote.
