Часто задаваемые вопросы
Why are there different carbon steel standards across the world?
Different countries have developed their own standards for carbon steel over time to suit regional industrial needs, regulations, and testing methods. This results in different naming conventions and grade classifications for the same material.
Can I use a steel grade from one standard in place of another?
In many cases, you can use an equivalent steel grade from another standard, but it is important to ensure that the mechanical properties, such as tensile strength and yield strength, align with your requirements. Always refer to the specifications provided by the standard.
How do I choose the right carbon steel grade for my project?
The right steel grade depends on your project’s requirements, including strength, corrosion resistance, and formability. Consult this table to find equivalent grades from different standards and select the one that best meets your application’s needs.
