Fastening components offer improved corrosion and acid resistance

Norelem has expanded its portfolio of products with the new A4 quality stainless steel connection elements for demanding environments. The new range offers higher corrosion and acid resistance.

The components include stainless-steel screws, nuts and washers and boast good workability and other mechanical properties that make them ideal for use in demanding environments.

The new A4 quality elements from Norelem complement the existing range of A2 quality elements. The range has significantly improved corrosion and acid resistance compared to A2 stainless steel, and therefore can be used in environments with a close proximity to salt water, such as shipyards. The higher salt content in both the water and air in these environments means that lower quality stainless steel components would rust immediately, making the A4 quality stainless steel connection elements ideally suited for these applications.

Marcus Schneck, CEO of Norelem, comments: “With our new range of A4 quality stainless steel connecting elements, we’re able to provide even more standard components capable of withstanding exposure to high demand environments, such as in the marine industry and in swimming pools which are subject to higher acidity levels.”

Stainless steel is generally thought of as one term to refer to particularly resistant metals with rust-proof properties, but there are in fact many different stainless steels made from over 160 different alloys. A4 stainless steels belong to the group of austenitic steels, which are also called chromium-nickel steels. It is the high chromium content of these stainless steels that make them so corrosion resistant and therefore so useful in environments with high acid contents.

Schneck adds: “Because of their excellent acid resistance, the Norelem A4 quality connecting elements are also suitable for applications in the chemical and food industries, alongside the pulp industry and in the renovation of chimneys and swimming pools.”

These A4 quality stainless steel connecting elements can be found in Norelem’s 2022 edition of The Big Green Book. Listing over 70,000 standard components, the two-volume catalogue is available in both print and online.
