Mild Steel

IS 2062 E350BR, IS 2062 E350B0, and IS 2062 E350C are different grades of Indian structural steel that adhere to the IS 2062 standard. Each grade has distinct characteristics and applications:

1. IS 2062 E350BR:-

   • BR stands for "Boiler Quality with Raised Temperature." This grade is suitable for applications where the steel will be exposed to elevated temperatures, such as in boiler and pressure vessel manufacturing.
   • It has a minimum specified yield strength of 350 MPa, making it a medium-strength structural steel grade.
   • E350BR is often used in applications where both strength and resistance to elevated temperatures are required, such as in the construction of boilers, pressure vessels, and heat exchangers.
   • The "BR" designation indicates that this grade has improved properties for high-temperature applications compared to the standard E350 grade.

2. IS 2062 E350B0:

   • B0 signifies that this grade has a minimum specified Charpy V-notch impact energy of 0 Joules. This indicates that it is a non-impact-tested structural steel grade.
   • E350B0 is used in applications where impact resistance is not a primary concern, such as in buildings and general structural engineering.
   • It has a minimum specified yield strength of 350 MPa, making it suitable for various structural applications where strength is essential.

3. IS 2062 E350C:

   • C signifies that this grade is suitable for cold-forming processes.
   • E350C is designed for applications where the steel will undergo cold forming, such as bending, rolling, and other shaping processes, without a significant loss of its mechanical properties.
   • Like E350B0, it has a minimum specified yield strength of 350 MPa, making it appropriate for structural applications that involve cold forming.

In summary, these three grades are variations of IS 2062 E350 with specific designations indicating their suitability for different applications and performance requirements:

• E350BR is used in high-temperature applications such as boilers and pressure vessels.
• E350B0 is a non-impact-tested structural steel grade used in general structural engineering.
• E350C is designed for applications involving cold forming processes while maintaining its mechanical properties.
