| Abstract: | Through lots of test analysis about mechanical properties and toughness（ drop hammer, im- pact） for 20 Mn steel, it puts forward that thermo mechanical rolling was proposed to reach 20 Mn steel mechanical properties and toughness comprehensive performance requirements of the rolling process. Cooling temperature and cooling speed is the main factors of 20 Mn steel affect mechanical properties and toughness（ drop hammer, impact. |
