Material Notes:

EOS Stainless Steel PH1 is a stainless steel powder which has been optimized especially for processing on EOSINT M 270 systems. This stainless steel prototyping material is tough and resistant to heat and oxidization. It is used in medical and aerospace applications and for complex applications such as tooling inserts with conformal cooling channels. PH1 can be tempered for improved finished part properties.EOS®, EOSINT®, DirectPart®, and DMLS® are registered trademarks of EOS GmbH. Information provided by Axis Prototyping.
