Additional Notes
Indian Standards (IS)
The Bureau of Indian Standards (BIS) publishes standards for various materials, including carbon steels. The IS 2062 standard is one of the most widely used for structural carbon steels.
AISI/SAE Grades
While Indian markets predominantly use IS grades, AISI (American Iron and Steel Institute) and SAE (Society of Automotive Engineers) grades like AISI 1018, AISI 1045, and AISI 1080 are also available and used, especially in specialized manufacturing and engineering sectors.
Hot Rolled vs. Cold Rolled
Carbon steels are available in both hot-rolled and cold-rolled forms. Hot-rolled steels are typically used for structural applications, whereas cold-rolled steels are used where precise dimensions and superior surface finishes are required.
Surface Treatments
Many carbon steel grades undergo surface treatments such as galvanization, painting, or powder coating to enhance corrosion resistance and surface durability, especially for structural and outdoor applications.
Conclusion
India's carbon steel market is robust, with a wide range of grades available to meet diverse industrial requirements. Understanding the specific IS codes and their corresponding properties is crucial for selecting the appropriate grade for your application. For precise specifications and standards, referring to the latest Bureau of Indian Standards (BIS)publications is recommended.
