Stainless steel is a type of steel. Steel refers to those containing less than 2% carbon (C), which is called steel, and more than 2% is iron. Adding chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), titanium (Ti), molybdenum (Mo) and other alloy elements during the smelting process of the steel improves the performance of the steel and makes the steel corrosion resistant (Ie no rust) is what we often say about stainless steel.

"Stainless steel fasteners" is a specific term concept covering a wide range of products. Stainless steel fasteners are often used for fastening of more expensive machine parts because of their beauty, durability, and strong corrosion resistance. With the progress of society, higher requirements have been put forward for stainless steel standard parts.
