Dab tsi ntawm steel phaj yog A516-70N + S5?
Dab tsi ntawm steel phaj yog A516-70N + S5?
A516-70N+S5 yog ib qho American standard hydrogen sulfide corrosion resistant steel phaj.
A516-70N+S5 yog hais txog cov qauv steel tshwj xeeb thiab qeb, tshwj xeeb:
A{{0}}N yog hais txog cov phaj kub-dov hlau rau cov hlab ntsha siab raws li American ASTM (American Society for Testing and Materials) tus qauv, tseem hu ua American standard A516-70. Qhov no yog cov hlau tsis tshua muaj carbon hlau. Cov ntsiab lus tseem ceeb ntawm cov hlau muaj xws li silicon, manganese, phosphorus, sulfur, thiab lwm yam. Nws cov ntsiab lus carbon tsawg, txog 0.2%, uas ua rau nws muaj qhov zoo weldability thiab formability.
S5 feem ntau sawv cev rau qib tshwj xeeb lossis cov kev xav tau ntxiv rau cov hlau, uas tuaj yeem xa mus rau qib siab ntawm cov khoom siv lossis kev ua haujlwm tshwj xeeb, xws li tiv thaiv hydrogen sulfide corrosion.
Txhawm rau ua kom tiav, A516-70N + S5 yog cov phaj hlau rau cov hlab ntsha siab uas ua tau raws li American ASTM cov qauv thiab tshwj xeeb tshaj yog tsim rau cov ntawv thov uas xav tau weldability zoo thiab corrosion kuj. Hauv kev siv tswv yim, xaiv cov khoom siv hlau phaj tsim nyog yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov qauv.
