    The A335 standard is applicable to seamless alloy steel tubes with high temperature nominal (average) wall thickness.
    Pipes ordered in accordance with this standard shall be suitable for bending, rolling (hot rolled back) and similar forming processes, as well as fusion welding.
    It can be selected according to design, working conditions, mechanical properties and high temperature characteristics.

    A335 P91

    ASTM A335 P91 is a pipe material type of ASTM A335. The pipe is suitable for bending pipe, rolling edge (hot rolled back) and similar forming and welding.Steel materials meet chemical composition, tensile properties and hardness requirements.A335 alloy pipe is also called seamless ferrite alloy steel pipe for high temperature.
