Stainless Steel

hexagon screws in Stainless Steel. With the addition of alloying elements to low Carbon steel such as Chromium and Nickel in high amounts, Carbon steel develops a resistance to corrosion or staining, and will not lose this resistance if scratched; it is then known as Stainless steel. With over 11% chromium, Stainless steel is about 200 times more resistant to corrosion than mild steel the alloying elements are a lot more expensive than normal carbon steel. In common fastener stainless steel grades, nickel can account for up 20% by weight but this can represent more than half of the value. Nickel prices fluctuate and this there could be a cost penalty for using stainless steel fasteners
