16Mn, high strength low alloy structural steel

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.

16Mn Steel is a carbon-manganese steel, carbon content of 0.16%, the yield point is equal to 343MPa (strength level belonging to 343MPa). Less the 16Mn steel alloy content, good weldability, and generally do not have to warm-up before welding.

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
