Application Selection and Material Limitations
S7 is not interchangeable with D2 when the primary requirement is maximum abrasive wear resistance. Common uses include impact tools, punches, chisels and heavy-duty tooling. 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.

Frequently Asked Questions
Which material condition should I order?
Annealed supply or specified hardened/tempered condition. Include the applicable purchasing standard, section size, certifications and target properties; heat-treatment schedules and mechanical values cannot be assumed across all conditions.
Can I substitute a similar grade?
S7 is not interchangeable with D2 when the primary requirement is maximum abrasive wear resistance. Obtain approval against the drawing and verify the ordered chemistry, mechanical properties, finishing response and documentation.
