Docol M are cold reduced fully martensitic steels. These steels are manufactured using special heat treatment in a continuous annealing line. The ultra high strength is produced by extremely fast water quenching from an elevated austenitic temperature range. Docol M grades are characterized by good formability at these high-strength levels combined with good weldability. All conventional welding methods can be used due to the lean chemical composition. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on forming. Filing Code: SA-687.
