Both 30CRMOV9 ROUND BARS and 21CRMOV5-7 ROUND BARS are identified as forerunners in important sectors like the oil and gas industry, automobiles and aviation. They serve as perfect components which withstand extreme conditions.
Suppliers and stockiest like Nilesh Steel Company, handle bulk requirements of these bars. With material testing certification the company offers the best products for different projects. This post offers a deep insight into our popular category of bars.
The information is designed to help you understand how to choose the supplies from us.
An overview of round bars
Round bars are made of different grades of steel for the oil and gas industry, automobiles and aviation. The properties are changed by the addition of different materials like Molybdenum, Carbon, Silicon, nickel, magnesium, chromium, Phosphorus, Titanium, and Sulphur. Their requirement for hardness depends on the ability to oxidize, weld, strength, and corrosion. Hence, there is a specific need for 30CRMOV9 ROUND BARS and 21CRMOV5-7 ROUND BARS. It helps the machine tool to complete the job at the site.
Nilesh Steel Company offers different round bars in varying lengths and diameters. Customers can order bars which are:
- Hot rolled
- Forged
- Cold forged
- Rough
- Polished
- Quenched
- Thermally treated
- Annealed
Serving the oil & gas industry
Various grades of carbon steel are required in the energy sector. The primary uses are for:
- Platforms and jackets
- Flow lines
- Structural components
- Oil country tubular goods
- Pipelines requiring high temperature
For example, the forging technique is essential to reshape the metal. It works well for components where steel strength should be heavy. The O & G applications for forging are done for:
- Valves and fittings
- Subsea equipment
- Wellheads
- Christmas trees
Main applications
- Heaters
- Rolls
- Boilers
- Reactors
- Steam generation device
30CRMOV9 ROUND BARS-Low alloy
This is a boiler-grade round bar and is applicable to temperatures below 540 degrees. It is commonly used for making screws and nuts. A few parts of the turbine and other equipment are also made with it.
- It is annealed softened
- Contains hardness HB of <248
- Tensile strength, Rm: 850 – 1300 MPa
Mechanical properties
- The yield point, Rp0,2: >590 MPa
- Elongation, A:> 8%
- Impact resistance, KV: > 20J
21CRMOV5-7 ROUND BARS
It is commonly used steel for boilers in the energy sector. It can withstand high temperatures of 550 degrees. Large forgings and small parts are supported by their presence. Its wide variety of applications includes steam turbine rotors, reservoirs & covers, shaft forgings and rotor blades. These round bars have specific low and elevated properties. The key requirement is for machining in Q&T condition.
