Stainless steel describes a family of steels highly resistant to tarnishing and rusting that contain at least two separate elements alloyed together. To answer this question, you first need to know some basic information about stainless steel. A2/A4 Stainless Steel; ISO 7380 Button Head Socket. Stainless steel describes a family of steels highly resistant to tarnishing and rusting that contain at least two separate elements alloyed together. DFM DFA Training forming bolt and screw heads, of extruding bolt shanks, and of roll threading increase strength values, often considerably.
