Partek’s spectrometer detects wave lengths of carbon to provide full characteristics of:

  • Carbon & Alloy Steels
  • Stainless Steels
  • Aluminum Alloys
  • Nickel Base Alloys
  • Tool Steel

Grade Identification

Partek performs hardness and chemical analyses to identify any specific ASTM/API grade material.

Field Metallographic Replication

Partek uses a nondestructive sampling procedure that records and preserves the topography of a metallographic
specimen to determine the stress limits of metals. Our field metallographic replication services are especially
useful to the fabrication industry for rolling metals.
