Application Selection and Material Limitations

Processing and tempering determine the balance of hardness, toughness and heat checking resistance. Common uses include hot forging dies, extrusion tooling, casting dies and machined die components. Suitability depends on grade chemistry, dimensions, strength and condition, the working environment and any surface or dimensional specifications. A related material should not be substituted solely because its marketing name sounds similar.

Centerless Grinding and Bar Finishing

Mozaic Precision Metals can review sourcing and centerless grinding, bar straightening, polishing, chamfering, cut-to-length and packaging for this product. Specify starting size, finished OD and diameter tolerance, length, surface roughness, straightness and inspection requirements separately. Actual capability depends on the material condition and geometry.
