Effect Of Various Elements On The Properties Of Stainless Steel Fasteners

Fasteners are very important in our life and production. They are widely used and have many kinds. In terms of material, there are generally carbon steel fasteners, stainless steel fasteners, and other fasteners. Among them, stainless steel fasteners are an important class of fasteners, perhaps some people will wonder why there are so many kinds of stainless steel, and each kind of use is different. As a professional fastener manufacturer, Xinchi fastener Company will be happy to introduce the classification basis of stainless steel, hoping everyone can choose the appropriate stainless steel fasteners according to their actual needs.

We need to know that the different elements contained in stainless steel fasteners are not the same to improve the product performance, each element has its unique role, Xinchi fastener company will introduce some of the more common stainless steel elements and their role.

Carbon (C) can improve the strength of stainless steel fasteners, especially its heat treatment performance, but with the increase of carbon content, the plasticity and toughness will also decrease and will affect the cold heading and welding performance of steel parts.

Manganese (Mn) can improve the strength of steel parts, and to a certain extent, it can improve the hardenability, which means that the intensity of hardening penetration is increased during quenching. Manganese also improves surface quality, but too much manganese is bad for ductility and weldability and can affect plating control.

Nickel (Ni) can improve the strength of stainless steel fasteners, the toughness at low temperatures, and the ability of atmospheric corrosion resistance. In addition, it can ensure a stable heat treatment effect, reducing the effect of hydrogen brittleness.

Chromium (Cr) can improve the quenchability of steel parts, abrasion resistance, and corrosion resistance. What’s more, it can also help maintain strength at high temperatures.

Molybdenum (Mo) can help control the quenchability, reduce the sensitivity of steel to tempering brittleness, and improve tensile strength at high temperatures.

Boron (B) enhances the quenchability of stainless steel fasteners and helps to produce the desired response of mild steel to heat treatment.

Alum (V) can refine austenite grains and improve the toughness of stainless steel fasteners.

Silicon (Si) can guarantee the strength of steel parts. Proper silicon content can improve the ductility and toughness of steel parts.

At present, the most used stainless steel on the market is 304 and 316, which contain elements that are very different. 304M, 304HC, and 316 are currently one of the most widely used materials of 300 series austenitic stainless steel. The obvious differences between various materials are: after cold working, the magnetic properties of the material are 316<304HC<304M. 316 material has better chemical corrosion resistance, corrosion resistance, and seawater corrosion resistance than 304M and 304HC.
