The difference between high-quality carbon structural steel and carbon structural steel

2016-02-19View Original

Thread Content

High-quality carbon structural steel (such as 08F) and ordinary carbon structural steel (such as Q235AF) have different methods for denoting their grades – why is it necessary to make this distinction? What are their respective uses? The method for indicating steel grades refers to GB/T 221-2008, Method for Designating Steel Product Grades

Without this standard, should we take a look at these two standards and compare them? GBT 700-2006 Carbon structural steel. GBT 699-1999 High-quality carbon structural steel
