❓ What is the maximum carbon content in low carbon steel?
✅ Common answers often include 0.1%, 0.2%, or 0.3%.
📚 Individuals tend to select one of these numbers based on their academic background or reference handbooks. However, it is important to understand that all of these values may be correct, as there is no standardized maximum carbon content for low carbon steel.
🔷 For instance, the ASTM A941, which defines steel terminology, does not specify a definitive carbon content limit. This is because the acceptable carbon content varies depending on the specific industry and application.
🔶 To illustrate, in the automotive sector, the maximum carbon content is typically around 0.1%, as specified by ASTM A1008. In contrast, for ASTM A516 Grade 70 plate, commonly used in the oil, gas, and petrochemical industries, the maximum carbon content can be as high as 0.3%.
