15MnNiNbDR belongs rau steel phaj yog lub siab kub siab lub nkoj nrog cov chav kawm ntawv, 15MnNiNbDR steel phaj yog qhov cuam tshuam kub ntawm rho tawm -45 degree, nrog lub zog siab, siab toughness yam ntxwv, 15MnNiNbDR steel phaj tshwm los sau cov kev lag luam qis. -kub ntim nrog cov hlau tsis tshua muaj hlau phaj hauv rho tawm 40 degrees ntawm rho tawm 70 degrees nrog cov hlau tsis muaj, feem ntau yog siv rau hauv kev tsim cov hlab ntsha uas tsis muaj qhov kub thiab txias, qhov kub thiab txias kheej kheej feem ntau siv hauv kev tsim cov hlab ntsha cryogenic siab, cryogenic kheej kheej cia. tanks, high-parameter cryogenic cylindrical hlab ntsha, cryogenic ethylene spherical tanks thiab lwm yam khoom siv.
Kev ua tiav ntawm 15MnNiNbDR: GB / T 3531.
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
Nco tseg: txhawm rau txhim kho kev ua haujlwm ntawm cov hlau, koj tuaj yeem ntxiv lwm cov kab ke;
PS: Cov tshuaj muaj pes tsawg leeg ntawm cov khoom tiav yuav tsum tau qhia nyob rau hauv cov ntaub ntawv ntawm cov hlau zeb.
