20CrMo impapuro zishyushye zishyushye

ibyuma bizenguruka ibyuma bikoreshwa cyane mugukora imashini, gukora autombile, gari ya moshi, imashini zicukura amabuye y'agaciro, imashini za peteroli, imashini zubuhinzi nububiko bwa gisivili nkubwoko bwose bwimigozi, imigozi, guhuza inkoni, ibikoresho byuma, ibikoresho, ibice bisanzwe, ibyuma bifata ibyuma, ibyuma byubaka, imiterere ibice by'imashini zikoresha imodoka n’ubuhinzi, amaboko yo hanze na iner, umuzingo n'imipira yo gukora.
GB 20CrMo ibyuma ni ubwoko bwibyuma byabashinwa bivanga mubyuma byububiko nubukanishi, bisanzwe bikoreshwa mukuzimya cyangwa kurakara cyangwa gutwika no kuzimya. 20CrMo ibikoresho bifite imbaraga zubushyuhe bwinshi, gukomera kwiza, nta burakari bukabije, plastike ikonje, imashini nziza no gusudira.

Porogaramu

20CrMo ibyuma bivangavanze bikoreshwa mugukora itangazamakuru ridashobora kwangirika mubikoresho bya chimique hamwe nu miyoboro yumuvuduko mwinshi, ibyuma bifata ibyuma, amashyanyarazi, ibyuma byo gutekesha no kwibagirwa hamwe nubushyuhe bwakazi buri munsi ya 250 ° C, hamwe nibice byingenzi bya karburizasi nkibikoresho na shitingi mumashini rusange . Irashobora kandi gukoreshwa mu cyuma cya 1Cr13 kugirango ikore ingufu ziciriritse, turbine yumuvuduko muke wa turbine murwego rwo hejuru rwumuvuduko ukabije wicyuma gikora.

Ibisobanuro byo kuvura ubushyuhe

• Ubushyuhe bwa mbere bwo kuzimya ubushyuhe: 880 ° C (Umukozi uzimya: amazi, amavuta)
• Ubushyuhe bwo gushyushya ubushyuhe: 500 ° C (agent - amazi, amavuta)

Amanota angana

20CrMo ibikoresho bihwanye na ASTM yo muri Amerika, Ubudage bwu Burayi DIN EN, Ubwongereza BS EN, Ubufaransa NF EN, Ubuyapani JIS, na ISO. (Kubisobanura)
