SA516Gr70 siab lub nkoj steel phaj nthuav dav qhia
Ua ntej, SA516Gr70 siab hlab ntsha steel phaj yog cov khoom siv qis-kub qis-alloy steel, feem ntau siv los tsim ntau lub nkoj siab thiab boilers, xws li plhaub, taub hau thiab raj phaj thiab lwm yam khoom. Cov hlau muaj zoo corrosion kuj, tsis tshua muaj kub toughness thiab siab zog, thiab lwm yam. Nws muaj zoo toughness thiab plasticity nyob rau hauv qis kub ib puag ncig thiab muaj peev xwm tiv taus siab thiab kub.
Thib ob, cov yam ntxwv ntawm SA516Gr70 siab lub nkoj steel phaj yog raws li hauv qab no
1. zoo weldability thiab workability;
2. siab zog thiab ductility;
3. zoo corrosion kuj;
4. haum rau siv nyob rau hauv qhov kub thiab txias ib puag ncig.
