Lederer GmbH continues to expand its premium stainless steel portfolio by adding fasteners made from 1.4462 (Duplex) and 1.4571 (A5 / 316Ti) to its stocked range. With this extension, Lederer responds to the growing demand for high-performance materials used in corrosion-critical and safety-relevant applications.

1.4462 (Duplex) has a special structure that gives it strong mechanical strength and great protection against rust, corrosion between its grains, and these properties make Duplex fasteners the preferred solution for challenging environments such as offshore and maritime applications, coastal architecture, chemical processing plants and desalination technology.

1.4571 (A5 / 316Ti) stands out due to its titanium stabilisation, providing reliable protection against intergranular corrosion – even after welding. This material is particularly well suited for use in chemical engineering, moderately corrosive industrial atmospheres, environmental and energy technology, as well as hygiene-sensitive sectors including food and beverage processing.

Both material grades offer good weldability and long-term material stability, meeting the highest requirements for industrial use. Selected fasteners – including hexagon bolts, threaded rods, nuts, washers and spring washers – are now available directly from stock, ensuring fast availability and reliable supply.

With this portfolio expansion, Lederer further strengthens its position as a competent partner for demanding stainless steel fastening solutions.
