SAE4340 Icyuma kizunguruka Icyuma ASTM4340 Icyuma
Ibiranga
Ibikoresho bya 4340 ibyuma nibyuma byubatswe.Bingana nu Budage DIN icyiciro cya 36CrNiMo4, Igifaransa NF gisanzwe 40NCD3, Ubuyapani JIS busanzwe SNCM439, BS yo mu Bwongereza BS 816M40, Abanyamerika SAE / ASTM4340, Abanyamerika UNS G43400 ， Ubushinwa 40CrNiMoA.
SAE4340 izwi nkibyuma byubaka ibyuma cyangwa ibyuma byinshi.Icyuma kirimo nikel hagati ya 1.65 na 2.00, ifite imbaraga nyinshi, ubukana, ubushobozi bukomeye, hamwe no guhagarara neza.Nyamara, ifite sensibilité nyinshi kubibara byera no kurakara.Gusoma nabi, bisaba ubushyuhe bwo hejuru mbere yo gusudira, kugabanya imihangayiko nyuma yo gusudira, no gukoresha nyuma yubushyuhe.
STANDARD: ASTM A29 / A29M-2012 cyangwa SAE J404

Ibisobanuro byo kuvura ubushyuhe
Yazimye kuri 850 ℃, amavuta akonje;Ubushyuhe kuri 600 ℃, amazi yarakonje, amavuta arakonja.
Gusaba
Bikunze gukoreshwa mugukora ibice byingenzi bifite imbaraga nyinshi hamwe na plastike nziza, no gukora ibice byingenzi bifite ibisabwa byihariye nyuma yo kuvura nitrati:
-Imashini ziremereye zifite imitwaro iremereye
-Igiti cyikigina gifite diameter irenga 250mm
-Uruziga rwa rotor ya kajugujugu
-Ibikoresho bya turbine, ibyuma, hamwe nibikoresho byinshi byoherejwe na moteri ya turbojet
-Ibikoresho bifata imashini, ibikoresho, nibindi.
Amapaki
1.Ku bundle, buri bundle uburemere buri munsi ya toni 3, kubuto bwo hanzediameter izengurutse umurongo, buri bundle ifite imirongo 4 - 8.
Igikoresho cya metero 2.20 kirimo ibipimo, uburebure buri munsi ya 6000mm
Ibikoresho bya metero 3.40 birimo ibipimo, uburebure buri munsi ya 12000mm
4.Ku bwato bwinshi, Ubwikorezi bwo gutwara ibintu ni buke kubwimizigo myinshi, kandi niniingano iremereye ntishobora gupakirwa muri kontineri irashobora koherezwa n'imizigo myinshi
