Yog li:
Zoo tib yam steel hlau (xws li 304): Quality qis dua S550GD + Z (304 tawm los tsuas yog 205mpa)
High-s zog stainless hlau (xws li 17-4 pH): farior rau S550Gd + Z (tawm ntau dua lossis sib npaug nrog 1100mpa)
Maintstream cov qauv hlau tsis muaj hlau (xws li 316/430): sib npaug rau lossis me ntsis qis dua hauv lub zog tshaj S550GD + Z
Stainless hlau muaj zoo corrosion tsis kam tshaj li galvanized steel, tab sis tus nqi yog siab dua
