Do you know which is better, American standard steel plate A36 or Q235B?

Shandong Kungang Metal Technology Co., Ltd. focuses on the production and sales of steel plates, and we have rich experience and reputation in the market. When purchasing steel plates, it is common to hear a comparison between American standard steel plates A36 and Q235B. These two types of steel plates have certain differences in performance. We will provide you with detailed descriptions of their performance from multiple perspectives and help you make wise purchasing decisions. Firstly, let’s compare these two steel plates in terms of strength. The yield strength of American standard steel plate A36 is 250MPa, and the tensile strength is 400-550MPa, while the yield strength of Q235B steel plate is 235MPa, and the tensile strength is 375-500MPa. From these data, it can be seen that the strength of American standard steel plate A36 is slightly higher than Q235B, which makes it more suitable for use in projects that require higher strength support.

Secondly, let’s compare their chemical composition. The chemical composition of American standard steel plate A36 contains carbon (C) content of 0.25%, sulfur (S) content of 0.05%, and phosphorus (P) content of 0.04%, while Q235B steel plate has carbon (C) content of 0.22%, sparse (S) content of 0.05%, and phosphorus (P) content of 0.045%. From the perspective of chemical composition, there is not much difference between these two types of steel plates, both of which belong to carbon responsibility structural steel and have good weldability and machinability.

In addition, there are some differences in corrosion resistance between American standard steel plates A36 and 0235B. Due to the high carbon content of American standard steel plate A36, it is prone to corrosion in environments with high humidity. Q235B steel plate has good corrosion resistance in general environments. For ordinary engineering projects, choosing Q235B steel plate can better protect the structure from corrosion. After that, we also need to consider the factor of weldability. The American standard steel plate A36 has good weldability and can be connected using conventional welding methods. However, Q235B steel plate has certain welding problems due to its low carbon content. In some projects that require high welding quality, choosing American standard steel plate A36 may be more reliable. Overall, there are certain differences between American standard steel plates A36 and Q235B in terms of strength, chemical composition, corrosion resistance, and coalability. If you need higher strength support and better corrosion resistance, you can choose American standard steel plate A36. If you have higher requirements for welding quality, you can choose Q235B steel plate.
