David Nguyen, Mechanical Engineering Lead
The grade 17-4 stainless steel bar is an age-hardening martensitic alloy meaning that is capable of attaining a wide range of strength and toughness properties depending on the precipitation or aging temperature used in hardening. It is the preferable steel of choice for the engineers and designer because of the amazing combination of high strength, good corrosion resistance and toughness in both base metals and welds. It is also known as 17-4 PH, UNS S17400, and Grade 630.
