Product specifications
Compare the full chemistry, physical properties and particle-size limits for four PM grades and two welding grades. Green density is specified at 600 MPa where a value is provided.
Product specification limits; actual batch results are provided in the shipment COA.
Chemistry and particle-size values are percentages. ≤ indicates a maximum; ≥ indicates a minimum. A dash or “Not stated” follows an unspecified source entry and does not mean zero. Select a grade to include it in your enquiry.
