p235gh steelnumber features and use

Pageviews:

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of P235GH steelnumber nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of p235gh steelnumber steel, can be used as an alloying element of low alloy steel.

The weldability of p235gh steelnumber is good. It means that under certain process and construction conditions, p235gh steelnumber 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.
