Tri Round Bars

In industry, stainless steel bars are commonly used due to their strength and formability. There are two types of steel bars that are commonly created and used: stainless steel bright bars and stainless steel black bars. In India, is the leading manufacturer and supplier of stainless steel bars.

It is possible to design a variety of machining components, including valves, fasteners, mechanical tools, studs, bolts, pins, hinges, and handles, as well as surgical & medical equipment, using a variety of raw tools formed from steel alloys. For example, the three main raw materials used for making valves, fasteners, mechanical tools, studs, bolts, pins, hinges, handles, and so on are bars, wires, and rods. Is one leading Manufacturer, Supplier & Stockist Of Round Bars.

In light of the increased strength and formability of stainless steel bars, these steel bars are widely used in industries. Stainless steel bars are primarily produced and used in two forms, that is, stainless steel bright bars and stainless steel black bars. 

Several people are curious about the differences between the two metals. Well, to answer those questions, we can say that there are some fundamental differences in the way these metals are processed at the mill. However, the Black bar meaning if we compare the products’ specifications or grades, there aren’t many differences. They can be formed to meet specific needs based on their strength, formability, and other characteristics.

To help you decide which one would be most beneficial for your business, let’s take a closer look at the key differences between bright bars and black bars in order to help you decide which would be the best choice How to blacken steel without heat.


Stainless Steel Black Bar:

By rolling the drawn steel through several rolls, the raw materials such as billets, blooms, and so on are heated at a temperature that is higher than the recrystallization temperature of steel. This is referred to as the rolling process. Steel can easily be formed into any desired shape and in a much larger size when it is heated to around 1200 C (approximately 2100 F). It is possible to make steel at this temperature range easily and in many different shapes. Generally, black metal bars are developed without the need for second reheating passes for accuracy, and so they are generally developed without any delays in the production process since they do not require any second reheating passes. Due to the fact that black bars shrink a little after cooling, this procedure does not allow for precise control over the size and shape of the bars, which is why black bars are more affordable than bright bars.

Steel is used when precise shapes and tolerances are not required, such as in the welding and construction trades for the manufacture of railroad tracks and I-beams, What is black steel can be used in a wide variety of situations.


Stainless Steel Bright Bar:

In simple terms, bright bars are more advanced than black bars when it comes to processing. In cold-reduction mills, bright bars are formed using the ‘drawing process’ and then cooled to room temperature before being further processed with annealing, turning, grinding, polishing, and tempering. As a result of this process, the shape and size of the steel bar can be controlled precisely without compromising its properties. Therefore, it allows the steel product to achieve close dimensional tolerances and a variety of surface finishes with the final product. A cold-drawn bright bar provides a superior surface finish as well as a higher degree of susceptibility, concentricity, and straightness than a hot-drawn bar. 

Compared to black bars, bright bars are more difficult to work with, and they are also comparatively more expensive compared to black bars.

Bright bars, however, are the best option when tolerances, surface condition, concentricity, and straightness are of utmost importance.
