Stop your search for steel round bar suppliers. Raj Bhoomi Engineers 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.
As a leading forged bar manufacturer, we understand the importance of quality. Each forged or hot rolled alloy steel round bar is heat-treated and undergoes a thorough quality check to ensure all metallurgical properties like grain size, microstructure, macro testing, ultrasonic testing, step turning, upsetting and detect any defects.

“High Quality at Cheapest Cost!”
The first step of production is the raw material collection, during which the unprocessed steel is gathered using the appropriate procedures. After that, the metal is tested chemically and physically. In the production process, using the proper testing protocol is essential. Here, particular tests are used to evaluate the durability of the gathered material. The next step is heating, in which they are heated under pressure. To acquire the shape, the steel is then rolled through one method. This enhances the ductility of stainless steel rods.
They are given the proper shape by the hot rolling process, which is a crucial production step that must be carried out carefully and by experts only. We ensure bar quality throughout the inspection phase, which comes next. Following the evaluation, a water-quenching method is another crucial step. Thermax systems are patented and are used to carry out the process under controlled conditions.
The product's ultimate condition is examined one more during the hot inspection procedure, which comes next. Here, professionals examine the performance and resistance criteria of round stainless steel bars. Our bars are employed in numerous building procedures as well as other uses. It is crucial to conduct physical testing to verify their strength and durability. Here, we guarantee the grade and performance prior to product shipping.
Manufacturing Process for Round Bars
The roudbars 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
They are also offered in bright condition by
- Peeling and Reeling (for upto 120mm for rolled)
- Cold drawing (for upto 65mm)
- Proof machining (greater than 120mm)
- Finish CNC machining
They are also offered in
- Cut to length
- Multiple lengths
Quality Check of Round Bars
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
- Cut to length
- Multiple lengths
