Enhanced with huge industry experience, we can mix and develop a wide combination of Steel

Casted Rolls based on customer needs. These Steel Casted Rolls are made using Chromium,

Nickel, Molybdenum which add to the long life of the role. With controlled heat treatment cycles

and other additives the wear resistance and rigidity of the roll is increased. The powerful and

strong development of these Steel Rolls allows these to offer high usefulness for different mills.

All Alloy Steel Rolls are ultrasonically examined and verified for any imperfections, and double

poured rolls checked for legitimate holding between the Shell and the Core. According to their

needs, one can get these Steel Casted Rolls in various standard sizes and particular features.

A steel round bar is a cylindrical metal bar made of steel that has numerous industrial and

commercial applications. A rolled bar manufacturer can produce many different types of round

bars. For example, a bright round bar is a steel bar that has had its surface condition made shiny

by a process called drawing, peeling, or grinding over a hot rolled steel round bar finish. These

bright round bars are often used in the manufacture of tools, bolts, screws, machine components,

fencing, automobiles, and more. The hot rolled bar is made by heating the steel so that it can be

formed in various shapes like round, square, flats etc hence it is called steel round bar, steel

square bar or steel flat bars respectively.

Another type of round bar is a forged or rolled alloy steel round bar. This type of steel has small

amounts of one or more alloying elements, such as manganese, chromium, nickel, titanium,

copper in the steel. Alloy steel is popular because it is widely available, easy to process, and has

good mechanical properties. This type of steel is more responsive to heat and mechanical

treatments than carbon steel. It is used for products such as shafts, gears, fittings, and more. Steel

round bars can be used for any number of applications with different finishes to suit customers’

needs and industries like mining, oil and gas, fasteners, automotive, agricultural

equipment,aerospace, defence, railways etc.

Stop your search for steel round bar suppliers. Punjabkart.com is your source for affordable hot

rolled or forged steel round bar products in a wide range of alloy steel grades.

From oil and gas, mining, fasteners to construction equipment, alloy steel round bars have one of

the most versatile product usage. Alloy steel offers higher tensile and yield strength and

increased wear resistance for various applications.

Some of the common grades are 42CrMo4, S355J2, SAE 4130, SAE 4140, SAE 8620,

20MnCr5, 34CrNiMo6, BS 970 grade like 70840, 709M40, 817M40 , EN series grades like

EN19, EN24, EN36C etc.

The cylindrical design makes the rolled alloy steel round bar suitable for direct machining of

components like axles, shafts, and many more.

Process Size (mm)

Hot Rolled 32 to 180

Hot Forged 100 to 450

Manufacturing Process

The round bars are made from ingots and are processed after giving required reduction ratio and discarding hot top and bottom to

homogeneity. They are either processed by hot rolling or hot forging. These bars are further heat treated by 

 Annealing

 Normalizing

 Stress Relieving

 Quenching and Tempering

 Spheroidizing Annealing

Quality Check

Following checks are conducted in round bars and reported in the TEST CERTIFICATE as per customer requirement

 Surface inspection (Magnetic Particle Inspection) is carried out of each bar end to end

 Positive Material Identification using XRF to certify in process chemistry of each bar

 100% dimensional verification using calibrated verniers and Go-No Go gauges

 Step down testing for bars up to Dia 60mm 

 Upset forging for using 150mm

 NMIR (Non-metallic inclusion rating) for inclusion rating

Application And End-Use

Various companies use our steel round bars for making final products in industries such as Oil and Gas, Power, Mining, Engineering

Goods, Fasteners, Railways, Defence, Load cells, Toolings etc
