Chemical composition characteristics of Carbon Steel Screws and Screws For Aluminum:
1. Carbon Steel Screw. We distinguish between low carbon steel, medium carbon steel and high carbon steel and alloy steel by the carbon content in the carbon steel material.
2. ① Low carbon steel with C%≤0.25% is usually called A3 steel in China. Foreign countries are basically called 1008, 1015, 1018, 1022 and so on. Mainly used for grade 4.8 bolts and grade 4 nuts, small screws and other products without hardness requirements. (Note: Drilling screws are mainly made of 1022 material.)
3. ②Medium carbon steel 0.25%
4. ③High carbon steel C%>0.45%. basically no use in the market
2. Alloy steel: Add alloy elements to ordinary carbon steel to increase some special properties of steel: such as 35, 40 chromium molybdenum, SCM435, 10B38. Commonly used SCM435 chromium molybdenum alloy steel, the main components are C, Si, Mn, P, S, Cr, Mo.
