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 tshwm los sau cov kev lag luam qis kub ntim nrog qis alloy steel phaj ntawm rho tawm 40 degrees ntawm rho tawm 70 degrees hauv kev siv cov hlau blanks, feem ntau siv rau hauv kev tsim cov khoom siv hluav taws xob kub siab, qis-kub Nws yog feem ntau siv hauv kev tsim cov khoom siv qis- kub siab cov hlab ntsha, qis-kub kheej kheej cia tso tsheb hlau luam, high-parameter low-temperature cylindrical hlab ntsha, low-temperature 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.
Ntim, cim thiab daim ntawv pov thawj zoo ntawm 15MnNiNbDR: Ntim, kos npe thiab daim ntawv pov thawj zoo ntawm steel phaj yuav tsum ua raws li GB / T 247.
Hlau phaj 15MnNiNbDR rau cryogenic hlab ntsha yog dav siv nyob rau hauv kev tsim cov cryogenic welded siab hlab ntsha. Hlau phaj rau cryogenic siab hlab ntsha muaj cov hlau ntshiab, tsis tshua muaj kev sib koom ua ke, kev ua haujlwm zoo, zoo muaj zog thiab tawv haum thiab tsis tshua muaj kub toughness, ua raws li tus qauv yuav tsum tau ua, tshwj xeeb tshaj yog kub-kub cuam tshuam toughness, uas yog ntau dua li cov txheej txheem.
