CNC machining

The 17-4 stainless steel bar belongs to the category of age-hardening martensitic alloys, which means it can achieve a diverse range of strength and toughness properties based on the precipitation or aging temperature employed during the hardening process. Engineers and designers prefer this steel due to its exceptional blend of high strength, excellent corrosion resistance, and toughness in both its base metal and weldments. It is also recognized by the names 17-4 PH, UNS S17400, and Grade 630.
