Hardox 400 Heat Treatment and Fabrication
HARDOX 400 has obtained its mechanical properties by quenching and when necessary by means of subsequent tempering. The properties of the delivery condition can not be retained after exposure to service or preheating temperatures in excess of 250oC (480o F).
HARDOX 400 is not intended for further heat treatment.For information concerning welding and fabrication, see our brochures on www.hardox.com or consult our Technical Customer Service.
Appropriate health and saftey precautions must be taken when welding, cutting, grinding or otherwise working on the product. Grinding, especially of primer coated plates, may produce dust with high particle concentration.
