  10. Welding Grade 91 Alloy Steel - Sperko Engineering

    Weld metal can be somewhat unpredictable in toughness due to variations in welding techniques by different welders and the possibility of weld discontinuities. Accordingly, Grade 91 should be hydrostatically tested at 70°F (19°C) or higher to be sure that the weld metal is above 15 ft-lbs or 15 mils lateral expansion.
