Hydrogen Determinator for Steel and Weld Metal

钢和焊缝金属用氢测定仪

Hydrogen embrittlement in welds and high-strength steel is controlled by measuring diffusible and total hydrogen. This determinator heats 0.5–5 g samples at 150–400 °C for diffusible hydrogen or fuses them up to about 2500 °C for total, detecting about 0.1 ppm. Precision is ≤2% at 10 ppm. Total runs take 2 min, diffusible 5–15 min.

Product Description 产品描述

Hydrogen embrittlement in welds and high-strength steel is controlled by measuring diffusible and total hydrogen. This determinator heats 0.5–5 g samples at 150–400 °C for diffusible hydrogen or fuses them up to about 2500 °C for total, detecting about 0.1 ppm. Precision is ≤2% at 10 ppm. Total runs take 2 min, diffusible 5–15 min.

Highlights

  • Diffusible and total hydrogen on one instrument
  • Large samples up to 5 g for weld coupons
  • Detection near 0.1 ppm
  • Nitrogen or argon carrier gas

Applications

  • Weld metal hydrogen control
  • High-strength steel embrittlement assessment
  • Plating bake-out verification
  • Pipeline and pressure vessel fabrication
