I-20CrMo ishidi yentsimbi eshushu

imivalo yentsimbi engqukuva isetyenziswa ngokubanzi ekwenzeni oomatshini, ukwenza i-autombile, uloliwe, oomatshini basemgodini, oomatshini bepetoleum, oomatshini bezolimo kunye ne-artectue yoluntu njengazo zonke iintlobo zeeshafti, izikrufu, iintonga zokudibanisa, izixhobo zehardware, iigiya, iindawo eziqhelekileyo, izibophelelo zespanners, izakhiwo. iinxalenye zemoto kunye noomatshini bezolimo, imikhono yangaphandle nangaphakathi, iirola kunye neebhola zokuzala.
I-GB 20CrMo intsimbi luhlobo lwentsimbi yaseTshayina ye-alloy yobunjineli kunye nenjongo yesakhiwo soomatshini, edla ngokusetyenziswa ekucimeni okanye ekufudumezeni okanye ekungcwatyweni nasekucimeni. I-20CrMo imathiriyeli inamandla aphezulu obushushu, ukuqina okulungileyo, akukho brittleness yomsindo, iplastiki ebandayo ebandayo, ukucwangciswa okulungileyo kunye nokutshisa.

I-20crmo ye-Alloy Steel Bar Ukuqulunqwa kwemichiza

IBanga	C	Si	Mnu	P	S	Cr	Mo
20CrMo	0.17-0.24	0.17-0.37	0.40-0.70	≤0.030	≤0.030	0.80-1.10	0.15-0.25

Inkcazelo ngoomatshini:

Tensile strength σb (MPa)	Unikeze Amandla σs 0.2 (MPa)	Elongation δ 5 (%)	Ukuncitshiswa kwendawo enqumlayo ψ (%)	Umsebenzi weBallistic Akv (J)	Ixabiso lokuqina αkv (J/cm2)	Ukuqina (HB)	Ubungakanani boMfanekiso
Min 835	Ubuncinci 540	Umz 10	Umz 40	Umz 47	Umz 59	Ubukhulu be-179	15mm

Usetyenziso

I-20CrMo intsimbi ye-alloy isetyenziselwa ukuveliswa kwemithombo yeendaba engabonakaliyo kwizixhobo zemichiza kunye nemibhobho yoxinzelelo oluphezulu, iziqhoboshi, ii-injini zomphunga, iibyila iibyiyila kunye ne-forgings kunye nobushushu bokusebenza obungaphantsi kwe-250 ° C, kunye neendawo ezibalulekileyo ze-carburizing ezifana nezixhobo kunye neeshafu koomatshini ngokubanzi. . Isenokusetyenziswa endaweni yentsimbi ye-1Cr13 ukwenza uxinzelelo oluphakathi, iiinjini zoxinzelelo oluphantsi zoxinzelelo oluphantsi kwindawo yoxinzelelo oluphezulu lwenqanaba loxinzelelo lwamagqabi asebenzayo.

Ukucaciswa koNyango lobushushu

• Ukucima ubushushu bokuqala: 880 °C (I-Agent yokucima: amanzi, ioli)
• Ubushushu bokufudumeza: 500 °C (i-arhente - amanzi, i-oyile)

Amabanga alinganayo

I-20CrMo imathiriyeli elingana ne-US ASTM, iJamani yaseYurophu iDIN EN, iBritish BS EN, iFrance NF EN, i-JIS yaseJapan, kunye nomgangatho we-ISO. (Ukwenzela ireferensi)
