Khoom Description
SA662GrC Pressure Vessel Steel Phaj yog ib hom kev kub siab thiab siab-siab nkoj steel phaj, uas belongs rau carbon manganese silicon steel, nrog zoo weldability thiab workability, haum rau tsim ntau yam high-pressure hlab ntsha, xws li boilers, siab hlab ntsha, lwm.
Nta ntawm SA662GrC Siab Vessel Steel Phaj: 1. zoo weldability thiab machinability; 2. zoo heev kub tsis kam; 3. zoo corrosion kuj; 4. zoo tsawg kub toughness; 5. zoo qaug zog tsis kam.
Cov tsis tseem ceeb ntawm SA662GrC Siab Vessel Steel Phaj yog raws li nram no: 1. thickness: feem ntau 6 hli -200 hli; 2. dav: feem ntau 1500mm-4000mm; 3. ntev: feem ntau 3000mm-18000mm; 4. tshuaj muaj pes tsawg leeg: carbon (C) cov ntsiab lus yog 0.19% ~ 0.22% Manganese (Mn) cov ntsiab lus yog 0.80% ~ 1.25%, silicon (Si) cov ntsiab lus yog 0.15% ~ 0.50%, phosphorus (P) cov ntsiab lus thiab sulfur (S) cov ntsiab lus tsis ntau tshaj 0.035%.
Lub siab lub nkoj steel phaj yuav muaj teeb meem hauv qab no hauv kev siv:
1. Corrosion: SA662GrC steel phaj yog qhov ua rau corrosion nyob rau hauv ib puag ncig hnyav xws li ntub dej, acidic thiab alkaline, uas cuam tshuam rau lub neej kev pab cuam ntawm steel phaj.
2. Kev qaug zog: Thaum raug alternating load rau lub sij hawm ntev, SA662GrC steel phaj yog nquag ua rau qaug zog tawg, uas cuam tshuam rau lub zog thiab ruaj khov ntawm steel phaj.
3. Vuam zoo: Yog tias qhov vuam zoo ntawm SA662GrC steel phaj tsis zoo, nws yuav yooj yim ua rau tawg, porosity thiab lwm yam tsis xws luag hauv qhov vuam, uas yuav cuam tshuam rau kev pab cuam lub neej ntawm cov hlau phaj.
4. Hardening: Thaum SA662GrC steel phaj raug kub siab rau lub sijhawm ntev, qhov tshwm sim ntawm hardening yuav yooj yim tshwm sim, uas yuav txo tau cov plasticity thiab toughness ntawm steel phaj thiab cuam tshuam rau lub neej kev pab cuam ntawm steel phaj.
Yog li ntawd, thaum siv SA662GrC siab hlab ntsha steel phaj, peb yuav tsum tau them sai sai rau cov teeb meem ntawm anti-corrosion, los tiv thaiv qaug zog, vuam zoo thiab kub tswj ntawm cov hlau phaj los xyuas kom meej kev ruaj ntseg thiab txhim khu kev qha siv cov hlau phaj.
