Steel Fasteners vs. Stainless Steel Fasteners
One question we get asked a lot around here is, “what type of steel fastener is better for my application?” The question refers to steel vs. stainless steel because they are different. Let’s see why.
Steel is an alloy made out of iron and carbon. The carbon percentage can vary depending on the grade – it’s mostly between 0.2% and 2.1% by weight. Though carbon is the main alloy material for iron, some other elements such as tungsten, chromium, and manganese can also be used to determine the hardness, ductility and tensile strength of steel. Heat treatment is a process which changes the mechanical properties of steels. This will affect the ductility, hardness and electrical and thermal properties of steel.
If we compare the strength of both steel and stainless steel, we should overlook the general misconception that one is stronger than the other. Stainless steel has a low carbon content which cannot be hardened, and regular steel is slightly stronger than grade 2 steel, and at the same time it is significantly weaker if compared in the terms of hardness. Both steels can have magnetic properties, but stainless steel is usually nonmagnetic. Some types of stainless steel are magnetic, except Series 3xx and 4xx. Such a type of stainless steel is cheaper, and does not normally have any addition of nickel. When compared to stainless steel, steel is magnetic.
