For the specific purpose of welding carbon steel pressure vessels at elevated temperatures, a high-quality chrome molybdenum alloy steel plate has been created. This particular type of steel plate has been designed with added molybdenum which gives it greater temperature tensile strength, as well as chromium which provides improved corrosion resistance, making it an ideal material for this type of application.
