The weldability of A387 Grade 12 Class1 vs A387 Grade 11 Class1 is good. It means that under certain process and construction conditions, A387 Grade 12 Class1 vs A387 Grade 11 Class1 can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

On March 26, 2020, the Mexican Ministry of Economic Affairs issued an announcement in the official gazette that the fourth anti-dumping sunset review investigation was initiated on A387 Grade 12 Class1 vs A387 Grade 11 Class1, hot rolled steel plates originating in Russia and Ukraine and boron-containing hot rolled steel plates originating in Russia. The TIGIE tax numbers of the steel products involved are 7208.10.99, 7208.26.01, 7208.27.01, 7208.38.01, 7208.39.01, 7225.30.04, 7225.30.05, 7225.40.03 and 7225.40.04.

The effect of nitrogen (N) on the properties of A387 Grade 12 Class1 vs A387 Grade 11 Class1 and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in A387 Grade 12 Class1 vs A387 Grade 11 Class1 and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
