Compare nine pressed stainless steel grades and six metal injection molding grades by chemistry, particle profile and powder properties. Choose the forming route first, then use the specifications to prepare a grade-specific enquiry.

Compare grade specifications, identify the forming route and share trial quantity and delivery requirements.
Choose pressed PM or metal injection molding before comparing alloy and particle requirements. The specification tables separate the density measures and production conditions that matter to each process.
For a current-grade comparison, include your alloy standard, process conditions, technical data sheet and recent COA.
Compare 15 grades by composition and powder properties. Select a grade to include it in your enquiry.
Product specification limits; actual batch results are provided in the shipment COA.
Bal. / Bal / Balance means the balance of the stated composition or size distribution. “Not specified” marks an empty or unlisted field. A dash (-) is retained from the specification and does not mean zero.
Scroll tables sideways to view all columns. The grade stays visible as you compare.
Start with the alloy chemistry, then compare the sieve profile and powder behaviour for pressing and sintering. Apparent density describes loose powder, while the green-density specification below applies at 600 MPa; neither is the tap-density measure used for MIM.

LS409L: the specification identifies Nb as 0.3–0.8%, although the original layout places it under the Cu heading. It is shown separately as niobium here; no copper value is specified. Nb values for other grades are not specified in this table.
Select the alloy and particle profile together with the intended feedstock, debinding and sintering process. These powders specify tap density and D50; the oxygen limits are different for water-atomized and gas-atomized powder and must be matched to the requested production route.

Compare all eight production routesUse the product specifications to compare grades and agree the acceptance requirements. The shipment COA provides actual batch results; process trials establish suitability for your pressing or MIM conditions.

Select a listed grade or send your target specification, and identify pressed PM or MIM. Include trial quantity, process conditions and any acceptance requirements.
