Kev qhia ntxaws ntxaws ntawm 16MnDR steel phaj
16MnDR yog cov hlau tsis tshua muaj siab-lub zog steel phaj nrog zoo heev toughness, weldability thiab corrosion kuj. Nws yog dav siv hauv roj av, tshuaj lom neeg kev lag luam, marine engineering, liquefied natural gas thiab lwm yam kev lag luam. Cov hauv qab no yog cov ncauj lus kom ntxaws txog 16MnDR steel phaj:
1. Tshuaj muaj pes tsawg leeg ntawm 16MnDR steel phaj
Cov tshuaj muaj pes tsawg leeg ntawm 16MnDR steel phaj feem ntau yog hlau (Fe), nrog rau cov ntsiab lus ntawm 99.0% mus rau 99.5%. Tsis tas li ntawd, nws tseem muaj cov pa roj carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), thiab lwm yam. Ntawm lawv, cov ntsiab lus ntawm Mn keeb yog 1.2% mus rau 1.6%, uas muaj cov nyhuv ntawm kev ntxiv dag zog rau cov khoom siv ntawm cov hlau phaj.
2. Mechanical zog ntawm 16MnDR steel phaj
Lub zog tensile ntawm 16MnDR steel phaj siab dua lossis sib npaug ntawm 1580MPa, qhov taw tes tawm los yog ntau dua lossis sib npaug rau 1420MPa, qhov elongation yog ntau dua lossis sib npaug li 22%, thiab qhov cuam tshuam lub zog yog ntau dua lossis sib npaug rau 39J. Cov khoom siv kho tshuab no ua rau 16MnDR steel daim hlau muaj lub zog siab thiab tawv, uas tuaj yeem ua tau raws li qhov xav tau ntawm kev siv engineering sib txawv.
3. Kev ua tau zoo ntawm 16MnDR steel phaj
16MnDR steel phaj muaj kev vuam zoo thiab tsis tshua muaj vuam tawg rhiab heev. Los ntawm kev siv cov cuab yeej siv vuam tsim nyog, cov khoom siv vuam zoo tuaj yeem tau txais los ua kom cov vuam zoo thiab kev nyab xeeb ntawm qhov project. Cov txheej txheem welding feem ntau muaj xws li phau ntawv arc welding, roj shielded vuam, submerged arc vuam, thiab lwm yam.
4. Corrosion kuj ntawm 16MnDR steel phaj
16MnDR steel phaj muaj corrosion kuj zoo nyob rau hauv chav tsev kub thiab muaj peev xwm tiv taus yaig los ntawm corrosive media xws li cua, dej, kua qaub, thiab alkali. Nyob rau hauv ib puag ncig marine, 16MnDR steel daim hlau tuaj yeem tiv taus seawater corrosion thiab ua kom lub neej ua haujlwm ntev ntawm cov qauv.
5. Daim ntawv thov teb ntawm 16MnDR steel phaj
16MnDR steel daim hlau yog dav siv hauv roj av, tshuaj lom neeg kev lag luam, marine engineering, liquefied natural gas thiab lwm yam kev lag luam. Hauv kev lag luam roj av, 16MnDR steel daim hlau tuaj yeem siv los tsim cov roj av cia tank, kav dej, flanges thiab lwm yam khoom siv; hauv kev lag luam tshuaj, lawv tuaj yeem siv los tsim cov reactors, kav dej, li qub thiab lwm yam khoom siv; nyob rau hauv marine engineering, lawv tuaj yeem siv los tsim cov nkoj, offshore platforms, Marine chaw thiab lwm yam qauv; nyob rau hauv daim teb ntawm liquefied natural gas, nws tuaj yeem siv los tsim cov tank cia, kav dej thiab lwm yam khoom siv.
