Open a grade to compare its characteristics, uses and processing needs. Choose a product within that entry to carry the grade into your specification.
17-4PH is strengthened through precipitation-hardening heat treatment.
Common uses include loaded mechanical parts and structural components requiring a specified aged condition.
Specify the required heat-treatment condition and whether machining takes place before or after ageing. Strength, toughness and inspection requirements belong in the component specification.
17-4PH is distinct from spring-oriented 17-7PH. The grade name alone does not define its final aged condition.
17-7PH is used for formed flat components that develop strength through a defined heat-treatment route.
Typical uses include springs, diaphragms and elastic formed parts.
For 17-7PH coil enquiries, specify a cold-rolled delivery condition, the forming sequence and required heat treatment. A general hard or soft description does not define the final heat-treated condition.
17-7PH and 17-4PH serve different fabrication needs. A general delivery-state label does not identify a precipitation-hardening treatment.
The specified heat-treatment or ageing condition and target hardness define the material condition required for your component.
Dimensions, surface finish and the planned forming or welding help define the material for your component.
Send the required product standard, tolerances and inspection documents. The grade, product form and delivery condition are reviewed together for the order.
Browse the product forms in this material family. For a grade-specific enquiry, use the product link inside the grade entry; you can also send a drawing or describe the part you need.
Send the drawing or specification for your component. Include any known grade, form, dimensions, heat-treatment condition and quantity, plus the delivery destination.
