SSAB M43 is a micro-alloyed steel grade for quench hardening. Its fine-grain micro-structure allows critical workshop operations without risk for micro-cracking. The self-tempering properties prevent formation of hardening cracks. The degree of hardness and toughness that can be achieved after heat-treatment will provide end products with a wear- and shock resistance ratio that ensures longer lifetime.
