The Difference Between Round Bar, Drill Rod and Shafting

Because the processes involved in its production allow us to extract metals and alloys and shape them into desirable forms to meet our needs and goals, humans have developed frontline competencies in metallurgy. Our development owes a great deal to the reliance on metals; hence the synergies with metallurgy! Various techniques are employed to manufacture metal products, depending on their nature, shafting defination and requirements.

The use of rods and bars ranges from building constructions and axles to frameworks and supports of different kinds. Round Bar Steel manufacturers in India are increasing production to meet the exponential demand in different infrastructure and engineering works. An expert from a leading manufacturer of rod steel discussed the popular products from metal mills and the differences between them. 

Round Bar:

Round bars are cylindrical lengths with diameters ranging from 14 inches to 2 feet, depending upon the application for which they are used. Round bars may be made of steel rods, stainless steel, aluminium, or brass. There are two types of steel round bars: hot-rolled, drill stock and cold-rolled. Prices Are Based On Round Bar Weight & Quality

Hot-rolled bars are used in applications where finish and precise measurements are less important, as in the construction industry. Cold-rolled bars are used in the manufacturing of supports, frameworks, braces, axles and motor shafts. Stainless steel round bars are used in applications where rust and corrosion resistance are critical.

Aside from being lightweight and easily machinable, aluminium round bars are corrosion resistant as well. While brass round bars are corrosion- and (electrical) spark-resistant, they have a high-level finish after polishing.

Shafting Bars:

Only a few stainless steel round bar manufacturers have developed the ability to manufacture these with utmost accuracy and finish; since their manufacture requires induction hardening, which is a non-contact process.

After placing the metal dowel rods in an electromagnetic field to heat them, they are plunged in water, oil, or a specific polymer to harden them. Among their uses are motor shafts, drive shafts, and brush bearings. As such shafts move at high speeds, straightness is an important attribute for most applications

Drill Rods:

A drill rod is made of tool steel that has been ground to a precise diameter. Drill rods material are usually oval, but they can also be square. Before they are machined, they are often tempered. As part of this procedure, the steel is heated to soften it and make it easier to work with. The steel is air cooled until machining can begin. A drill rod is commonly used to make drill bits, taps, dowel pins, shafts, and reamers. Hammers, files, and punches are also made from them.

There Are 2 Types Of Drill Rods

1. Water Hardened Drill Rods
   Drill rods that are water hardened are less alloyed than drill rods that are oil hardened, allowing them to be machined more quickly. During water hardening, the sounding rod is heated until it glows red, then immersed in water to cool. The result is a hard, robust metal that can be easily machined. However, it is not suitable for welding. In the production of hammers and files, water-resistant drill rods are used.
2. Oil Hardened Drill Rods Drill rods that are water hardened are less alloyed than drill rods that are oil hardened, which allows them to be machined more quickly. appDrill rods that are water hardened are less alloyed than drill rods that are oil hardened, which allows production of hammers and files. The rod is heated until it glows red and then immersed in a vat of water to cool during the water hardening process. As a result, a hard, robust metal that is easily machined is made.
