16Mn is a kind of high strength low alloy structural steel, the carbon content of 0.12% -0.20% to join main alloying elements manganese, silicon, vanadium, niobium, and titanium.
But because the 16Mn steel hardened tendency is slightly larger than the low-carbon steel, so at low temperatures (such as winter open operation) or welded on the structure of large rigidity, large thickness, to prevent cold cracking, the need to take the preheated measures.
The main chemical compositions(%) of 16Mn:
Carbon | 0.12-0.20 |
Silicon | 0.20-0.60 |
Manganese | 1.20-1.60 |
