Stainless Steel Grades

At TAD INOX, we utilize a wide range of stainless steel grades, each with unique properties and specifications to meet the stringent requirements of different industries.

In addition to chromium steels (ferritics) and chromium-nickel steels (austenitics), TAD INOX also supplies spring stainless steel, tailored to customer-specific tensile strength and hardness requirements.
