Alloy 926 (1.4529) screws are the perfect replacement for 316L when higher corrosion resistance is required without increased strength. Alloy 926 fasteners are considered a 6-molybdenum alloy (6-molybdenum or 6% molybdenum), similar to sister alloys AL6XN and SMO 254. In the stainless steel category, these 6 molybdenum alloys are considered very corrosion resistant.
