Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel EN10025-4 S420ML steel price can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.

The JIS G3106 EN10025-4 S420ML steel price specification is a hot-rolled carbon steel plate for welded structures. The EN10025-4 S420ML steel price steel grades include: SM400A/B/C, SM490A/B/C, SM490YA/YB, SM520B/C, SM570.

The weldability of EN10025-4 S420ML steel price is good. It means that under certain process and construction conditions, EN10025-4 S420ML steel price 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.
