The issue of overseas products' tanks being prone to damage was resolved with "hard chrome plating"!
We would like to introduce a case where a tank made overseas was prone to damage, causing difficulties. [Issue] We received an inquiry from a manufacturer who needed a tank for mixing marble raw materials that required hardness. However, the overseas-made tank was easily scratched, and there were numerous scratches in areas where the plating had peeled off. [Proposal] The original overseas-made tank had a very thin hard chrome plating, and particularly near the junction of the inner diameter bottom and the inner diameter surface, there was almost no plating at all. Therefore, we proposed to apply our "hard chrome plating" more thickly. [Result] The hard chrome plating applied by another company had scratches after just one use, but after our delivery, the tank was used several times without any issues, and the customer was satisfied.

basic information
**Characteristics of Hard Chrome Plating** ■ Hardness Generally considered to be above Hv700. At Otec, we provide high hardness plating of over Hv900 by adjusting the liquid composition. ■ Wear Resistance It has a low friction coefficient and excellent wear resistance. ■ Heat Resistance Heating above 400°C causes a rapid decrease in hardness. At Otec, we use a dedicated furnace for baking to remove hydrogen after plating, conducted under strict temperature control. ■ Corrosion Resistance Stable against chemical agents other than chlorides. ■ Oil Retention Due to the fine cracks on the plating surface, it has excellent oil retention properties. If further enhancement of oil retention is desired, we can also accommodate porous chrome plating with widened cracks.
