BÖHLER M261 - Precipitation hardening plastic mould steel with a controllable dimensional change during heat treatment. Good machinability due to added sulphur.
BÖHLER M303 - Stainless martensitic chromium steel, offering excellent toughness, corrosion and wear resistance. It is characterized by improved machinability and polishability.
BÖHLER M238 - The hardened and tempered plastic mould steel. Because of the Ni-addition there is no hardness decrease in the center of large sizes over 400 mm thickness.
BÖHLER M268 - Hardened and tempered plastic mould steel with excellent cleanliness for best polishability. The hardness is constant over the entire cross-section of the steel block, even at large sizes, due to the addition of nickel.
