Benefits of Hard Chrome

Can be applied to a wide variety of shapes and sizes - Hard chrome is suitable for complex and irregular shapes, such as holes and bores.

Harder than most abrasives and steel counter faces - At 850-100Hv (65-70Rc), hard chrome can withstand high-stress contact against sand, cement, glass fibers, and more. 

Provides a bright and appealing finish - Hard chrome is a great option when it comes to parts that will be visible or placed on display.

Resistant to corrosion - With hard chrome plating being highly resistant to corrosion, plated industrial parts are less likely to become rusted or damaged when exposed to elements such as oil.

Produces low friction - Hard chrome reduces friction, lowering the risk of overheating and ensuring a more effective performance during high-powered operations.
