Technical Data
The “ shah group “ deals in high quality stainless steel products through it’s group companies and distribute via it’s wide network throughout the country . “Stainless steel” is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the 'passive layer'. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion . Also adding other elements like nickel , molybdenum, titanium , and niobium changes the mechanical & chemical properties of the steel .
