Pressure riveting nuts, cylindrical nuts, screws and bolts of standard parts are essential in daily life and industrial production. Pressure riveting screws, studs, nuts and bolts are also called industrial instruments. Standard parts play an important role in the industry. As long as there is industry, the use of fasteners is always very important. For example: Carbon Steel Rivet Nuts and Knurled Rivet Nuts.
Pressure riveting nuts, nut posts, screws and bolts of standard parts are usually used to process different materials according to the strength grades of the nut posts, nuts, screws and bolts. Currently, the standard parts on the market mainly include carbon steel, stainless steel and copper.
Carbon steel is an iron-carbon alloy with a carbon content Wc of less than 2.11%. Also called carbon steel. Usually, it also contains small amounts of silicon, manganese, sulfur and phosphorus. Generally, the higher the carbon content of carbon steel, the higher the hardness and the higher the strength, but the lower the plasticity.
{1}According to the application, carbon steel can be divided into three types: carbon structural steel, carbon tool steel and free-cutting structural steel. Carbon structural steel is divided into engineering structural steel and mechanical manufacturing structural steel.
{2} According to the smelting method, it can be divided into open hearth steel and converter steel.
{3} According to the deoxidation method, it can be divided into boiling steel, killed steel, semi-killed steel and special killed steel;
{4} According to the carbon content, carbon steel can be divided into low carbon steel (WC≤0.25%), medium carbon steel (WC0.25%-0.6%) and high carbon steel (WC> 0.6%);
{5}According to the quality of steel, carbon steel can be divided into ordinary carbon steel (high phosphorus and sulfur), high quality carbon steel (low phosphorus and sulfur) and high quality high carbon steel (low phosphorus and sulfur)) and super high quality steel.
Carbon steel: We distinguish low carbon steel, medium carbon steel, high carbon steel and alloy steel according to the carbon content of carbon steel materials.
(1) Low carbon steel with C%≤0.25% is usually called A3 steel in China. It is basically called 1008, 1015, 1018, 1022, etc. abroad. Mainly used for grade 4.8 bolts, grade 4 nuts, small screws and other products without hardness requirements. (Note: Drilling nails mainly use 1022 material)
Dongguan Rosenton Hardware Technology Co., Ltd. mainly uses 1008 1006 1022 raw materials for pressure riveting screws, nuts, studs and bolts. SAE1008 is a standard of the American Society of Automotive Engineers. 10 means Mn is less than 1%, and 08 means carbon content. The main difference between 1008 and 1006 and 1010 is the carbon content. SAE is the American steel grade representation method.
According to the results of the existing data query, the main differences between chemical composition 1006 and 1008 are:
{a}The carbon content is inconsistent: the carbon content of 1006 is less than 0.08, and the carbon content of 1008 is less than 0.10
{b}The manganese content is inconsistent: the manganese content of 1006 is less than 0.45, while the manganese content of 1008 is less than 0.50
(2) Medium carbon steel, product p is 0.25%
