Steel grades comparison table
Steel is one of the most important materials to use in the construction industry, and it is important for people in the industry to understand the different steel grades available. For example, when it comes to imported steel, there is not always an exact match between the grade of steel and the grade of steel code for domestic steel in the same industry. This article will explain the relationship between imported steel grades and domestic steel grades, and also provide a comparison table of commonly used steel grades and imported steel grades.
Commonly used steel grades
Of the numerous grades of steel available, some are used more widely than others. In construction, the most popular steel grade is generally structural steel, which is commonly known in the industry as Structural Steel 34 (SS34). SS34 is the domestic steel grade and is used in most applications in the construction industry in North America; however, some applications require imported steel. In this case, it is important to understand the differences between the standard grade of steel and the imported steel grade.
Import steel grades
In imported steel grades, there are slightly different standards used. For instance, in stainless steels, the standard numbers used are often lower than those used in the US market. For example, stainless steel grade 304 (1.4301) is the standard grade for European markets, whereas stainless steel grade 316 is the standard for US markets. For this reason, when looking for imported steel, it is important to double-check that the grade specified is the correct grade for the intended application.
Comparison table
In order to provide a more comprehensive overview of the different steel grades, a comparison table is included below. The table includes the standard grades of both domestic (SS34) and imported steel.
Domestic Steel SS34 Number Imported Steel Number;
Carbon Steel SS34 A523 1018 A333 Gr. 3
Alloy Steel SS34 4130 AISI 4137 AISI 4140
Tool Steel SS34 S7 AISI M2 AISI M42
Stainless Steel SS34 304 1.4301 316L 1.4401
Conclusion
Steel grades are an important factor to consider when purchasing or using steel in the construction industry. This article has provided a comparison table of domestically produced steel grades and imported steel grades, which should serve as a helpful guide for those in the industry. It is important to note that although the comparison table includes commonly used steel grades, different grades will be used for different applications. As such, it is important to ensure that the correct grade of steel is used for the specific application.
