Icyuma gito cya karubone martensitike idafite ibyuma 1.4418, X4CRNIMO16-5-1, Z8CND17.04, S165M, ukurikije EN 10088-1, AIR 9160. 1.4418 Ibigize imiti: Carbone C: ≤0.06 Silicon Si: ≤0.70 Manganese Mn: ≤1.50 Fosifore. P. Imwe mumanota ya martensitike hamwe no kurwanya ruswa ihagije, imbaraga nziza hamwe nubukomere bwinshi hamwe no kugabanya karubone.Icyuma gifite imbaraga nziza cyane no kurwanya ruswa yingingo zasuditswe, kurwanya umunaniro, ibipimo byiza cyane mubushyuhe buke, hamwe no kurwanya ruswa ugereranije nicyuma cya austenitis 18-8.Mubyongeyeho, ifite solderabilité nziza.Ibikoresho bitangwa cyane cyane muburyo bwinkoni bikoreshwa mukubyara ibicuruzwa, inteko ziteranirizwamo turbine, nuts na bolts, shaft, pin, piston, shitingi nkuru, crankshafts, abigaragambyaga mubikorwa bya shimi, ingufu, inyanja, kubaka ubwato, ikirere / kirogenike.Ibikoresho bya mashini bitanga umusaruro imbaraga RP0.2 MPA Imbaraga zingutu RM MPA Kurambura [%] Ubukomezi [HB] Akabari ≥750 900 - 1100 ≥16 280 - 340 QT900 920 1050 18 300

Uburyo bwo kuvura ubushyuhe: Gukoresha no kuzimya kuri 950 kugeza 1050 ° C, hanyuma ugahita ushushe kuri 600 ° C mumasaha 8, hanyuma ugakonja mukirere.Nigute gusudira?Nziza, karubone nkeya ya martensite hamwe na austenite yatatanye neza itanga umusaruro mwiza wa HAZ mugihe cyo gusudira.Gushyushya kugeza kuri 100 ° C - 200 ° C birasabwa kubice byinshi cyane cyangwa guhangayikishwa nyuma yo gukonja.
