Application Selection and Material Limitations
Water quenching can increase distortion/cracking risk versus oil- or air-hardening grades. Common uses include small punches, cutters, chisels and basic tool 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.

Frequently Asked Questions
Which material condition should I order?
Annealed machining condition; final quench, temper and dimensional allowances must be planned. 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?
Water quenching can increase distortion/cracking risk versus oil- or air-hardening grades. Obtain approval against the drawing and verify the ordered chemistry, mechanical properties, finishing response and documentation.
