Material identification of high-strength nuts

Material identification of high-strength nuts

Plain, blackened, and galvanized are generally ordinary carbon steel nuts. Nuts generally have performance levels. Stainless steel is generally A2-70. When distinguishing between carbon steel nuts and stainless steel nuts, it is easy to know with a magnet that stainless steel nuts will not be attracted by the magnet. Stainless steel products are generally bright silver in color.

A nut is a nut, a component that is used to tighten together with a bolt or screw, and is a necessary component for all production and manufacturing machinery. According to different materials, it can be divided into several types, including carbon steel, stainless steel, and non-ferrous metals (such as copper). According to the attributes, there are mainly national standards (GB), German standards (DIN), international standards (ISO), Japanese standards (JIS), American standards (ASTM/ANSI), and other standards.

The company's main products include high-strength bolts, high-strength nuts, steel structural bolts, steel structural nuts, grid sealing plates, grid bolts, etc.
