What Is The Difference Between Black Bar And Bright Bar ?

Stainless Steel Black Bars A black bar is formed by the 'rolling process', in which raw materials such as billets and blooms are heated while being passed through several rolls. It occurs at a temperature of around 1200 C (approximately 2100 F), which is higher than steel's recrystallization temperature. It is possible to sculpt steel into any desired shape at these temperatures and to produce larger shapes than those possible at lower temperatures.

Stainless Steel Bright Bars: Steel or metal bars that have undergone one or more cold finishing processes are called bright bars. Since no or very little heat is applied throughout the entire process of transforming hot-rolled bars (also referred to as black bars) into cold-finished bars or bright steel bars, these processes are referred to as cold finish processes or cold finished end products. A bright bar is a stainless steel bar with a bright finish.

The increased strength and formability of stainless steel bars has made them widely used in industries. It is usually Stainless Steel Bright Bars and Stainless Steel Black Bars that are created and used most frequently. Our customers often ask us what the difference is between black steel and bright drawn steel. In terms of their fundamental properties, these two types of metal differ a great deal.
