17-4 PH Stainless Steel – Markforged

17-4 PH stainless steel is a high-strength, high-hardness metal with excellent corrosion resistance. This versatile steel is widely used in the manufacturing, aerospace, petroleum, and medical industries. If heat treated, it has an ultimate tensile strength of 1250 MPa and a Rockwell Hardness of 36 HRC.

17-4 PH Stainless steel is best heat treated to maximize strength, hardness, or toughness. H900 condition, heating your part to 900F (482C) for four hours, yields the strongest and hardest possible parts. H1150 condition (1150F instead of 900F) can also be used to maximize toughness at the expense of ultimate tensile strength.


17-4 PH Stainless Steel is a hard, stiff, and corrosion resistant stainless steel. It excels in manufacturing environments and as low volume parts.
