Alloy steels
1 the two Numbers beginning steel grade steel, carbon content by an average of carbon content, such as a few extremely 40Cr.
2 major steel alloy elements, in addition to the individual micro alloying elements, general with several per cent said. When the content of 1.5% average alloy steel grade, "mark symbol in general only, and do not indicate content, but in special circumstances, easy confounding element symbols in the standard to figure" 1 ", such as steel grade "12CrMoV" and "12Cr1MoV", the former chrome content of 0.4-0.6 percent, while the latter was 0.9-1.2%, the composition all the same. When the content of p 1.5% average alloying elements, 2.5%, 3.5%... When, in the symbol should be marked content, but behind the corresponding said for 2, 3, 4... Etc. 18Cr2Ni4WA example.
3 the vanadium, titanium, stainless steel, aluminum V Ti AL, boron B, rare earth elements, such alloy light-yellow belong to the micro alloying elements, although content is low, still be in steel grade drawings. 20MnVB such as steel. Vanadium 0.07-0.12%, boron for 0.001-0.005%.
4 senior high-quality steel should be in steel grade finally add "A", to distinguish from general quality steel.
5 the alloy steel, steel grade label (or suffix) represents the material USES symbols. For example 30CrMnSi screw steel rivet, steel grade for ML30CrMnSi said.
