Yes, Stainless Steel 348 Stud Bolts are recyclable. Stainless steel is highly recyclable and retains its properties even after recycling processes. Recycling stainless steel helps conserve natural resources, reduces environmental impact, and contributes to the circular economy by minimizing waste and energy consumption in manufacturing.
Stainless steel 348 stud bolts are generally not indicated for underground use because of their susceptibility to corrosion in certain underground areas. When exposed to water, chemicals, and other subsurface materials in the presence of surfaces, it can lead to accelerated deterioration, compromising the integrity of the packaging.
Stainless steel 348 stud bolts are rarely used in potable water systems due to their high corrosion resistance and oxidation resistance, which may not be necessary for potable water systems. Stainless steel grades with low alloy content and corrosion resistance well, such as 304 or 316, which are widely selected
A variety of stainless steel 348 stud bolt systems include:
Full thread stud bolts: Bolts with threads running the full length.
Double End Stud Bolts: Bolts threaded on both ends to secure two objects.
Tap and Stud Bolts: Bolts threaded at one end and a non-threaded side at the other for easy installation.
