Cov noP460NH kub khoomyog dab tsi cais NH los ntawm P460N. Lawv txhais covP460NH kub siab tshaj plawsrau yield-raws li tsim ntawm 400℃- yog li ib phab ntsa loj ntawm ambient 460 MPa yuav roughly 56 % dhau lawm. Ntawm 300℃cov txiaj ntsig siv tau poob mus txog 294 MPa; ntawm 400℃qhov tsim tawm yog 235 MPa, ze li ib nrab ntawm chav tsev{10}}kub tus nqi. Tsim kom muaj qhov kub thiab txias - tus lej tshwj xeeb, tsis yog cov kab ntawv xov xwm 460 MPa, yog ib kauj ruam tseem ceeb tshaj plaws hauv kev qhia P460NH rau kev pabcuam kub. Tshaj li 400℃tus qauv tsim hloov mus rau creep / stress{17}} cov ntaub ntawv tawg, uas ua rau qib siv tau txog li 500℃.

Qhov zoo
Tus nqi lag luam ntawm P460NH yog ntsuas tau, tsis zoo nkauj:
Thinner phab ntsa ntawm qhov kub thiab txias.Tawm tsam P355NH ntawm tib lub siab thiab qhov kub thiab txias, P460NH khiav roughly 15% thinner - cov khoom siv tsawg dua, qhov hnyav dua, vuam yooj yim dua.
Designable rau 400℃los ntawm yield.Tus txheej txheem luam tawm Rp0.2 ntawm qhov kub thiab txias, yog li cov kws ua haujlwm tuaj yeem loj tuaj yeem ncaj qha es tsis xav txog qhov cuam tshuam.
Zoo weldability.Cov pa roj carbon sib npaug nyob ib puag ncig 0.45 thiab qis impurity theem (P Tsawg dua lossis sib npaug rau 0.025 %, S Tsawg dua lossis sib npaug li 0.015 %) khaws preheat thiab PWHT cov kev xav tau me me piv rau qis - alloy steels.
Siab ncaj ncees raws li -welded.100% weld-seam NDT thiab qhov yuav tsum tau xau kuaj txhais tau tias lub raj tuaj txog npaj rau kev pabcuam siab yam tsis muaj kev tshuaj xyuas dua.
Tus nqi sib npaug.Nws sau qhov sib txawv ntawm cov pa roj carbon steel (tsis muaj zog txaus) thiab 16Mo3 / 13CrMo4-5 (tshaj -tshwj xeeb thiab kim dua) rau cov dej num nruab nrab-kub.
Daim ntawv thov
P460NH raug xaiv qhov twg cov kab ua haujlwm siab tshaj qhov ntsuas kub thiab qhov chaw siab dua - qhov kub thiab txias tawm los txo cov phab ntsa tuab thiab qhov hnyav piv nrog P355NH lossis carbon- qib manganese. Hom kev siv:
