    Solving the three toughest challenges in stainless fabrication

    stainless steel weld passivation corrosion vs clean

    Weld corrosion→passivated

    We apply post-weld pickling, electropolishing
    and ASTM A967 passivation to eliminate
    chromium carbide depletion. Your parts stay
    rust-free even in medical /marine
    environments.

    large stainless part distortion control flatness fixture

    Large-part distortion→controlled

    Stress relieving fixtures, adaptive clamping
    and simulation software keep flatness within
    0.1mm/m on parts up to 4m.No springback
    surprises.

    stainless steel surface finishing mirror vs brushed

    Surface defects→ mirror / brushed

    Robotic polishing, 8k mirror finish, consistent
    #4 satin. We match your approved sample –
    even for complex 3D contours.
