+86-18057366698 Contact UsStandard Parts Rivet Nuts Nuts Screws Bolts are essential in everyday life and in industrial manufacturing. Rivet Screws Stud Nuts Bolts are also known as industrial meters. Standard parts are an important task in the industry. As long as there is industry on the earth, the function of fasteners is always important.
Standard parts rivet nuts Nut column Screws Bolt processing common materials are based on the nut column nut screw bolt strength level using different materials, the current market standard parts are mainly carbon steel, stainless steel, copper three materials. The following small screw will give you a brief introduction to the knowledge of the carbon steel of the first product of the fasteners. I hope that everyone can help.
Carbon steel is an iron-carbon alloy having a carbon content Wc of less than 2.11%. Also called carbon steel. It also generally contains small amounts of silicon, manganese, sulfur, and phosphorus. Generally, the higher the carbon content of carbon steel, the greater 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 construction steel and machine-made 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 (F), killed steel (Z), semi-killed steel (b) and special killed steel (TZ);
(4) According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25% - 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 in phosphorus and sulfur), high-quality carbon steel (low in phosphorus and sulfur) and high-quality steel (low in phosphorus and sulfur). ) and premium quality steel.
Carbon steel: We distinguish low carbon steel, medium carbon steel and high carbon steel and alloy steel with carbon content in carbon steel.
1. Low carbon steel C% ≤ 0.25% Domestically known as A3 steel. Foreign countries are basically called 1008, 1015, 1018, 1022 and so on. It is mainly used for products with no hardness requirements such as 4.8 bolts and 4 grade nuts and small screws. (Note: the drill tail nail is mainly made of 1022 material)
Nut Posts Screws Bolts mainly use 1008 1006 raw materials, SAE1008 is the American Society of Automotive Engineers standard, 10 represents Mn less than 1%, 08 represents carbon content; the main difference between 1008 and 1006 is the carbon content. SAE is the US steel number representation method.
The results of the existing data query, the main differences between the chemical composition of 1006 and 1008 are:
a, carbon content C is inconsistent: 1006 contains C less than 0.08, 1008 is less than 0.10
b, the amount of manganese (Mn) is inconsistent: 1006 contains Mn less than 0.45, 1008 is less than 0.50
2, medium carbon steel 0.25% <C% ≤ 0.45% Domestically known as 35, 45 steel, foreign countries are basically called 1035, CH38F, 1039, 40ACR and so on. Mainly used for 8 grade nuts, 8.8 grade bolts and 8.8 grade hexagon sockets.
3. High carbon steel C%>0.45%. Currently it is basically not used on the market.
4. Alloy steel: Adding alloying elements to ordinary carbon steel, adding some special properties of steel: such as 35, 40 chromium molybdenum, SCM435, 10B38.
