 32Mn2Si2A basic introduction

32MnZSiZA due to its good mechanical properties is often used as a defensive shield of steel is widely used in ordnance production. 

But because of its high carbonequivalent (0.643), when the weld is larger, 

weld distribution is not ideal, weld willbe difficult. Especially not when 

preheating before welding, cold crack problem is particularly prominent.
