20CrNiMo (8620H) ibyuma bizengurutse ibyuma bizunguruka

GB 20CrNiMo alloy Steel nicyuma cyiza cyo kuzimya no gutondekanya Alloy Structural ibyuma, kandi ni ibya karubone yo mu rwego rwo hejuru, chromium nkeya, molybdenum, nikel ikomera ibyuma. Amavuta yazimye & Tempered Hardenss ni 28-34 HRC. GB 20CrNiMo ibyuma Annealing itanga gukomera munsi ya 250HB.

GB 20CrNiMo Alloy yubatswe ibyuma ni Nickel chromium molybdenum alloy ibyuma byerekana. 20CrNiMo Hamwe na karuboni yo hasi iringaniye, So GB 20CrNiMo ibyuma bifite gusudira neza.

Porogaramu

GB 20CrNiMo ibyuma bikoreshwa cyane mubikorwa bitandukanye bikoreshwa mu nganda z’imodoka n’ubwubatsi kubafite ibikoresho nibindi bikoresho. Porogaramu zisanzwe nkimibiri ya valve, pompe nibikoresho, Shaft, umutwaro muremure wibiziga, bolts, imitwe ibiri-imitwe, ibikoresho, nibindi

Kuvura ubushyuhe Bifitanye isano

• Annealing ya 20CrNiMo Alloy ibyuma byubaka

Buhoro buhoro ushushe kuri 850 ℃ hanyuma wemere ibihe bihagije, reka ibyuma bishyushye neza, Hanyuma bikonje buhoro mumatanura. Ibyuma 20CrNiMo bivanze bizabona MAX 250 HB （Gukomera kwa Brinell）.

• Gukomera kwa 20CrNiMo Alloy ibyuma byubaka

Shyushya buhoro kugeza kuri 880-920 ° C, Noneho nyuma yo gushiramo bihagije kuri ubu bushyuhe bwamavuta. Ubushyuhe mugihe ibikoresho bigeze kubushyuhe bwicyumba.

GB 20CrNiMo ibyuma bikoreshwa cyane mubikorwa bitandukanye bikoreshwa mu nganda z’imodoka n’ubwubatsi kubafite ibikoresho nibindi bikoresho. Porogaramu zisanzwe nkimibiri ya valve, pompe nibikoresho, Shaft, umutwaro muremure wibiziga, bolts, imitwe ibiri-imitwe, ibikoresho, nibindi

Ingano isanzwe no kwihanganirana

Uruziga ruzengurutse ibyuma: Diameter Ø 5mm - 3000mm

Isahani yicyuma: Ubunini 5mm - 3000mm x Ubugari 100mm - 3500mm

Icyuma cya Hexagonal: Hex 5mm - 105mm

Abandi 20CrNiMo ntabwo basobanuye ingano, nyamuneka nyamuneka hamagara itsinda ryacu ryo kugurisha inararibonye.

Gutunganya

GB 20CrNiMo alloy ibyuma bizenguruka umurongo hamwe nibice birashobora kugabanywa kubunini bwawe busabwa. Byongeye kandi, 20CrNiMo alloy ibyuma byubutaka birashobora kandi gutangwa, bigatanga ibikoresho byujuje ubuziranenge ibyuma byerekana ibyuma byubutaka ibyuma byihanganira ibyo usabwa. Byongeye kandi, GB 20CrNiMo ibyuma nabyo birahari nka Ground Flat Stock / Isahani ya Gauge, mubipimo bisanzwe kandi bitujuje ubuziranenge.
