What is a Stainless Steel Round Bar?

Reputed for strength, tenacity, and corrosion resistance, these bars are staples in construction and engineering. Stainless steel round bar supplier in India cater to applications like beams, columns, and automobile parts. A stainless steel round bar provides high-temperature tolerance and tensile strength.

What is the manufacturing process of a stainless steel threaded bar and a stainless steel round bar?

The standard approaches are hot-rolling and cold-drawing. Manufacturers produce threaded bars by cutting the stainless steel round stock (preferably premium raw materials) per the buyer’s requirements. The heat-treated steel gets molded into the threaded rod, which undergoes heat preservation, magnetization, and electroplating. PMI (Positive Material Identification) of an SS round bar and ultrasonic examination ascertain step-wise quality.

What are the different finishes available for a stainless steel cold rolled bar? How are they achieved?

Buyers can choose multiple finishings for a stainless steel cold rolled bar – mill-issued, mechanically polished, or customized, like architectural. They conform to the specified surface roughness (Ra) and will depend on the production, thickness, and abrading.

Classic options include polished, bright annealed (or BA), pickled, or buffed for a mirror finish. 2B, created by annealing, pickling, and tempering, is used for cold-rolled stainless steel rounds.

How is the corrosion resistance of a stainless steel hex bar determined? Which factors can affect it?

A flexible hexagonal rolled stainless steel bar withstands corrosion and impact. The corrosion resistance gets analyzed via ultrasonic testing, immersion tests, or a salt spray analysis. The measurement is in millimeters per year (mils). The amount of elements like chromium and molybdenum and the protective coating affect sustainability. Routine cleaning and maintenance also prolong the service life.

What is the difference between cold-finished and hot-finished stainless steel round bars?

A hot rolled stainless steel round bar is produced by heating the raw material to over its recrystallisation temperature. A hot rolled stainless steel bar is cheaper but may have scaling and a rougher finish. SS Rod suppliers in India supply cold-finished bars for better precision and premium finish. These get drawn below the recrystallisation point and undergo turning, grinding, and polishing.

What is the tolerance level of the diameter of an SS rod 2mm?

An SS rod follows rigid guidelines for tolerance to suit demanding industrial functions. For stainless steel rods of 2mm, the value is 0.03 mm under or over. Or, it translates into +/- 0.001 in inches.
