Oxygen-Nitrogen Analyzer for Steel

钢用氧氮分析仪

Melt shops, bearing steel producers and welding consumable makers track oxygen and nitrogen to control inclusions and toughness. This inert gas fusion analyzer heats 0.3–1 g to 2500–3000 °C, measures oxygen from 0.1 ppm to 0.5% and nitrogen to 3%, with ≤1.5% RSD at 50 ppm. Each run takes 60–120 s. Tell us your steel grades.

Product Description 产品描述

Melt shops, bearing steel producers and welding consumable makers track oxygen and nitrogen to control inclusions and toughness. This inert gas fusion analyzer heats 0.3–1 g to 2500–3000 °C, measures oxygen from 0.1 ppm to 0.5% and nitrogen to 3%, with ≤1.5% RSD at 50 ppm. Each run takes 60–120 s. Tell us your steel grades.

Highlights

  • Total oxygen as an indicator of steel cleanliness
  • Sub-ppm to percent ranges in one analyzer
  • Fast cycle for production control
  • Helium carrier for stable detection

Applications

  • Steel melt shop gas control
  • Inclusion assessment by total oxygen
  • Bearing and tool steel qualification
  • Welding consumable testing
