In demanding industrial environments, the integrity of a structure often depends on its smallest components: the fasteners. 2205 Duplex Stainless Steel Bolts have emerged as the “workhorse” of the industry, offering a superior alternative to standard grades like 316. Understanding why we need these high-performance Alloy 2205 Bolting solutions requires looking at their unique chemistry, history, and the critical roles they play across global industries.

Manufacturing 904L bolts is significantly more difficult than manufacturing standard 304 or 316 grades. While 904L is highly ductile, its high nickel (25%) and molybdenum (4.5%) content make it extremely tough and prone to rapid work-hardening,  When welding 904L studs or components, use matching filler metals (e.g., 20 25 CuL) and avoid pre-heating to prevent hot cracking. Use Tri-Roll Thread Comparators and calibrated gauges to ensure precision, as 904L is prone to galling (seizing) during assembly if threads are not perfect.
