The Carbon Content In Carbon Steel Rivet Nut

Standard parts are indispensable in daily life and industrial manufacturing. Standard parts have important tasks in the industry. As long as there is an industry on the earth, the function of fasteners will always be important. The carbon steel rivet nut is also one of the fasteners, and it is also very important.

We distinguish low-carbon steel, medium-carbon steel, high-carbon steel, and alloy steel based on the carbon content of carbon steel materials.

Low carbon steel C%≤0.25% is usually called A3 steel in China. It is 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: 1022 material is mainly used for the self-drilling nail.)

Medium carbon steel 0.25%3, high carbon steel C%>0.45%. At present, it is not used in the market.

Alloy steel: Add alloy elements to ordinary carbon steel to increase some special properties of steel: such as 35, 40 chromium-molybdenum, SCM435, 10B38. Fangsheng screws mainly use SCM435 chromium-molybdenum alloy steel, the main components are C, Si, Mn, P, S, Cr, Mo.

It can be seen that there are still many classifications of carbon steel rivet nut, and flat head rivet nut can also have many classifications, such as small flat head and large flat head.
