Stainless steel bolts are a staple for most construction and industrial projects. They are always in high demand because of their extreme reliability. Noted for their resistance to corrosion, stainless steel bolts (SS bolts) are equally if not stronger than regular steel in some instances.
When compared to unhardened Grade 2 steel, stainless steel bolts are slightly stronger. Understand that SS bolts are built out of iron along with approximately 18% chromium and 8% nickel, at least when considering the classic 18/8 SS bolt. These fasteners do have a low carbon content and are incapable of being hardened like regular steel. That’s the catch. Harden steel is typically stronger than stainless steel bolts, so you need to be aware of the actual qualities in the bolts you are choosing to use.
Besides 18/8, stainless steel bolts also come in 18/10 and 18/0 designations. The 18/10 means the bolt consists of 18% chromium and 10% nickel. The 18/0 means that the bolt has 18% chromium but no nickel compounds. Know that the higher the numbers the more corrosion resistant you can expect it to be and the less magnetic.
In general, SS bolts are less magnetic than regular steel and do not stain, corrode, or rust as easily as ordinary steel. Both of these factors should be considered when selecting the right fastener.
