is a common misconception that stainless steel is stronger than regular
steel. In fact, due to the low carbon content, stainless steel cannot
be hardened. Therefore when compared with regular steel it is slightly
stronger than an un-hardened (grade 2) steel fastener but significantly
weaker than hardened steel fasteners. Stainless steel is also much less magnetic than regular steel fasteners though some grades will be slightly magnetic.
