Precautions

• Avoid prolonged exposure to highly concentrated oxidizing media.
• Strict temperature control is required during forging and hot forming.
• Solution annealing followed by rapid cooling is recommended after hot working.
• Avoid direct contact with carbon steel during processing, storage and transportation.
• Confirm wall thickness, end dimensions, pressure rating and design temperature before installation.
