Stainless Steel is an iron-containing alloy made from iron ore, chromium, silicon, nickel, carbon, nitrogen, and manganese. The properties of the final metal change depending on varying amounts of these elements. There are over 150 grades of stainless steel, of which 15 are most commonly used.

Healthy Human products are made from the highest quality 18/8 food-grade steel. The numbers stand for the percentages of chromium and nickel in the steel. So, there is 18% chromium and 8% nickel in the stainless steel that we use. Chromium increases hardness and nickel gives Healthy Human products their unbelievable strength. Together these two products make it highly resistant to rust or stains. The reason why it is the material of choice in the food processing, dairy, and brewing industries is due to the fact that it is easy to clean, durable, and clean.
Here at Healthy Human, we do regular product performance and material safety testing through independent, accredited laboratories to ensure that we meet food contact regulatory requirements and that we meet our own exactingly high standards of safety.
