NK F47 steel phaj yog cov khoom siv tshwj xeeb tsim los siv rau hauv kev tsim khoom hauv nkoj thiab kev siv dej hiav txwv engineering. Lub phaj muaj cov yam ntxwv tshwj xeeb uas ua rau lawv tsim nyog rau kev tiv thaiv cov kev xav tau nruj ntawm ib puag ncig marine.
Cov tshuaj muaj pes tsawg leeg ntawm NK F47 steel phaj yog ua tib zoo sib npaug kom ntseeg tau tias kev ua haujlwm zoo. Cov phaj no feem ntau muaj xws li carbon, silicon, manganese, phosphorus, sulfur, chromium, molybdenum, npib tsib xee, thiab tooj liab. Qhov sib piv ntawm cov ntsiab lus no ua kom lub zog tensile siab, zoo heev corrosion kuj, thiab zoo weldability.
