High Quality Steel Grade Correspondence Table
High quality steel is widely used in various fields across the world, and it’s important to have the appropriate steel grade for the particular application. All steel grades are manufactured to different standards, depending on the country and region production. Steel grades are specified using codes and symbols; domestic steel grade codes and symbols are different from international ones. This article takes into consideration domestic steel grades and their international counterparts.
Chrome Steels
Chrome steels are of high quality and are widely used in the production of car bodies, construction of bridges and other engineering works. Domestically produced chrome steel is generally designated by their symbols such as S50C, SCM420 and SK3. The international counterparts are AISI 1049, AISI 4140 and AISI 1060 respectively.
Alloy Steels
Alloy steels are being used for various industrial applications. Domestically produced chromium molybdenum steel is designated as SCM440 and its international counterpart is AISI 4140. Similarly, chromium-vanadium steel is designated as SCM415 in domestic production and AISI 4130 as its international partner.
High Strength Low Alloy Steels
High strength low alloy steels (HSLA) are commonly used for industrial applications. HSLA steel is produced in the form of plate and cold-rolled steel with the following grades: domestic SUS304-H, SUS304-F and SUS420J2; and their international counterparts are AISI 304-H, AISI 304-F and AISI 420J2 respectively.
Stainless Steels
Stainless steels are produced to serve various industrial purposes. The domestic grades of stainless steel are: SUS304, SUS321 and SUS430; and the international grades are AISI304, AISI321 and AISI430 respectively.
Tool Steel
Tool steels are used for machining different kinds of materials in industrial applications. Some of the domestic tool steel grades include: H13T, M2, O7 and W1; and the international grade correspondents are AISI H13, AISI M2, AISI O-1 and AISI W-1 respectively.
Mild Steels
Mild steels are low-carbon steel with low amounts of alloying elements and are used for various applications such as car bodies, construction and engineering works. The common grade of mild steel in domestic production is SPHE, and the international counterpart is AISI 1006.
Free Cutting Steels
Free cutting steel is extensively used for machining operations. The domestic and international counterparts of this steel grade are 2C15H, 3C16H and S58C respectively, and their international equivalents are AISI 1141, AISI 1144 and AISI 1115.
Conclusion
This article provides a correspondence between domestic steel grades and their international counterparts. This correspondence is important in order to ensure that the right grade of steel is used in a particular industry to ensure the efficient and successful production of the desired product. Therefore, this article highlights the importance of familiarizing oneself with the different domestic and international steel grades and their correspondences.
