Sustainability in the Fastener Industry 2022-2023

Estimated Read Time:

2022 may bring even more pressure for industries to turn to more sustainable and recyclable products. With this scenario, many industries move towards more recyclable and “green” fasteners. As a result, the stainless steel fastener industry could shine. Stainless steel not only lasts longer due to its chromium content. However, it also requires less maintenance and more easily recycled. Having a trusted custom industrial and premium fastener supplier may become essential as the world turns to more “green” products.

What makes stainless steel “stainless”?

Stainless steel fasteners contain as much as 10% chromium depending on the alloy and grade of stainless used. Chromium reacts with oxygen to form a hard, thin protective layer around the fastener, protecting it from corrosion. While the introduction of chromium is primary factor for preventing corrosion, other elements such as Nickel, Molybdenum, and Manganese also enhance the characteristics.

ASTM Grade Stainless Steel

While your application may require stainless steel, it may also require certain mechanical requirements such as tensile strength and yield strength. When this is the case, you must use custom fasteners fabricated with this in mind and ensure to meet the minimum mechanical requirements. Lilly Fasteners offers a full range of stainless (ASTM A193, ASTM F593, etc.) to meet your most sensitive mechanical requirements.
