Stainless Steel Round Bars

Stainless Steel Round Bars Manufacturer & Supplier In India

Stainless steel Round Bars are carefully designed parts which are produced under high quality grades of stainless steel. These bars are highly applied in industries because of their remarkable strength and durability as well as their natural resistance to corrosion. We have the best stainless steel round bars, which are used to provide high levels of performance even in the harsh operating conditions like at Unifit Fastener.

A characteristic of stainless steels, in general, is the presence of chromium, which improves oxidation and resistance to corrosion. An increase in chromium elevates the capacity of the bar to resist water, chemicals, and extreme weather patterns. It is due to this that the Stainless Steel Round Bars are favored in the field of structural, mechanical and industrial application, which is also known as Stainless Steel Rods.

The choice of bar size, shape, and grade is based on the engineering requirements. We have various stainless steel grades depending on the environment and mechanical requirements. Besides the round profile, the bars can also be offered in square, hexagonal, and custom extruded profiles.

Unifit Fastener is offering stainless steel bars produced according to a standard known as ASTM A276, which deals with hot-rolled, cold-drawn, and annealed stainless steel bars (not forged bars). This guarantees a uniform quality, dimensional precision, and extended service service in different applications.

FAQs about Stainless Steel Round Bars

What are stainless steel round bars used for?

Stainless steel round bars are widely used in industries that require high strength, durability, and corrosion resistance. They are commonly used for manufacturing shafts, fasteners, tools, machine components, and structural parts. These bars are also ideal for applications in construction, automotive, marine, chemical processing, and food production because they withstand moisture, chemicals, and high temperatures.

What is the price of an SS 304 round bar?

The price of an SS 304 round bar varies depending on its diameter, length, manufacturing process, and order quantity. Factors like surface finish (hot rolled or cold drawn) and current market rates for stainless steel also influence the final cost. For an accurate and customized SS 304 round bar price, you can contact Unifit Fastener with your specific size and quantity requirements.

What is better, 304 or 316 stainless steel?

The price of an SS 304 round bar varies depending on its size, finish, and quantity, so it is best to request a customized quote for accurate pricing. When comparing 304 and 316 stainless steel, 316 offers higher corrosion resistance because of its molybdenum content, while 304 is more economical and suitable for general-use applications, making the better choice dependent on your specific environment and performance needs.
