15MnNiNbDR belongs rau cov hlau phaj yog lub siab kub siab lub nkoj nrog cov chav kawm, 15MnNiNbDR Dance Steel Hlau Phaj yog qhov cuam tshuam kub ntawm rho tawm -45 degree, nrog lub zog siab, siab toughness yam ntxwv, 15MnNiNbDR steel phaj tau tshwm sim los sau cov kev lag luam Cov thawv kub uas tsis tshua muaj alloy steel phaj ntawm rho tawm 40 degrees ntawm rho tawm 70 degrees nyob rau hauv kev siv cov hlau blanks, feem ntau yog siv nyob rau hauv lub tsim ntawm kub kub siab hlab ntsha, low-temperature Spherical tanks, high-parameter low-temperature cylindrical hlab ntsha. , low-temperature ethylene spherical tanks thiab lwm yam khoom siv. Tshwj xeeb tshaj yog qhov kub-kub ntim phaj ntawm WISCO, kev ua tau zoo, kev ua haujlwm kub zoo tib yam kom muaj kev ua haujlwm zoo.
15MnNiNbDR tus qauv kev tswj hwm: kev siv lub teb chaws tus qauv GB / T 3531 tus qauv.
Lub xeev xa khoom ntawm 15MnNiNbDR: lub xeev xa khoom dav dav yog normalized + tempered. ps: yog tias cov neeg siv khoom xav tau lwm lub xeev xa khoom tshwj xeeb yuav tsum tau teev tseg hauv daim ntawv cog lus.
Cov tshuaj muaj pes tsawg leeg ntawm 15MnNiNbDR (kev tshuaj ntsuam melting%):
C: tsawg dua lossis sib npaug rau 0.180
Si: nruab nrab ntawm 15-0.50 Mn: nruab nrab ntawm 1.20-1.60
P: tsawg dua lossis sib npaug rau {{0}}.020S: tsawg dua lossis sib npaug rau 0.010
Ni: nruab nrab ntawm {{0}}.30-0.70 Nb: nruab nrab ntawm 0.01-0.04
Al: {{0}}.015Cr: tsawg dua lossis sib npaug li 0.45
15MnNiDR steel phaj rau cryogenic hlab ntsha yog dav siv nyob rau hauv manufacturing cryogenic welded siab hlab ntsha. Cov hlau phaj rau cryogenic siab hlab ntsha uas tsim los ntawm Dancing Steel muaj cov hlau ntshiab, tsis tshua muaj kev sib koom ua ke, kev ua tau zoo, lub zog zoo thiab tawv thiab kub tsis tshua muaj siab, uas ua tau raws li tus qauv yuav tsum tau ua, tshwj xeeb tshaj yog qhov kub thiab txias cuam tshuam toughness, uas yog ntau dua. tus qauv yuav tsum tau.
