STELMI 500 HR CHROME BARS
STELMI'S STANDARD OF 0.001'' MIN. PLATE THICKNESS PER SIDE GIVES 500+ HOURS OF NEUTRAL SALT SPRAY CORROSION RESISTANCE
Stelmi America, LLC uses its unique and proprietary plating method to produce hard chrome plated steel bars that are more dimensionally uniform and 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 B117 neutral salt spray standard. The 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 process. Corrosion ratings are evaluated using ISO 10289 with virtually all test samples showing zero corrosion after testing.
.001" min CR = 500 hours min salt spray = Zero Corrosion in neutral salt spray testing
