Q370R boiler steel phaj muaj siab tensile thiab yield zog, uas ua tau raws li cov khoom siv zog yuav tsum tau rau cov hlab ntsha siab. Qhov qis elongation yuav tsum tau qhia tias steel phaj lub plasticity yog me ntsis txo thaum lub sij hawm tsim khoom, tab sis nws tseem muaj txaus toughness. Kev cuam tshuam qhov hnyav yog los ntsuas lub peev xwm ntawm cov hlau los tiv thaiv kev puas tsuaj ntawm qhov kub thiab txias, thiab kev sim ua kom muaj kev nyab xeeb ntawm Q370R steel phaj nyob rau hauv qhov qis - qhov kub thiab txias.
Q370R nkoj steel phaj daim ntawv thov ntau yam
1. Kev tsim cov hlab ntsha siab: Q370R steel phaj muaj lub zog siab, zoo siab ua haujlwm thiab zoo weldability, uas yog tsim rau kev tsim txhua yam nruab nrab thiab qis - cov hlab ntsha siab, xws li cov tso tsheb hlau luam, reactors thiab lwm yam.
2. Petrochemical kev lag luam: Q370R steel phaj yog dav siv nyob rau hauv petrochemical kev lag luam, xws li roj refinery, roj cia tank, roj pipelines thiab hais txog.
3. Kev lag luam tshuaj: Q370R steel phaj feem ntau siv hauv kev lag luam chemical los tsim txhua yam khoom siv tshuaj, xws li reactors, sib cais yees, thiab lwm yam. Nws muaj kev tiv thaiv zoo corrosion thiab siab tsis kam.
4. nuclear fais fab nroj tsuag: lub siab hlab ntsha nyob rau hauv lub nuclear fais fab nroj tsuag yuav tsum muaj kev kub siab tsis kam thiab kev nyab xeeb kev ua tau zoo, tsim nyog rau kev siv cov high - zog steel cov ntaub ntawv.
