STELMI 1000 HR CHROME BARS
STELMI'S STANDARDS OF 0.001" MIN. PLATE THICKNESS PER SIDE GIVES 1000+ HOURS OF NEUTRAL SALT SPRAY CORROSION RESISTANCE
By adding extra chrome plate layers, Stelmi America, LLC uses its unique and proprietary plating method to produce hard chrome plated steel bars that are far more corrosion resistant than those produced by conventional processes.
Stelmi America offers chrome plated bars and induction hardened chrome plated bars with an increasing range of corrosion resistance as tested against the ASTM B 117 neutral salt spray standard. Corrosion resistance of our products and/or process is verified utilizing both in-house and certified independent laboratory testing.
Stelmi America's chrome plated steel bars achieve their remarkable corrosion resistance purely from the chrome plating. Corrosion ratings are evaluating using ISO 10289 with virtually all test samples showing zero corrosion after testing.
