What are the latest A131 grade D ship repairing steel prices

Oxygen is a harmful element in A131 grade D ship repairing steel steel. With the increase of oxygen content, the strength of A131 grade D ship repairing steel steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of A131 grade D ship repairing steel steel.

In the first ten days of February 2020, the key statistics show that steel enterprises produce a total of 19.3943 million tons of crude steel, 17.9747 million tons of pig iron, 17.5904 million tons of steel and 3.225 million tons of coke. This ten day average daily output of A131 grade D ship repairing steel crude steel is 1939400 tons, down 2.68% on a month on month basis, up 3.16% on a year-on-year basis; steel is 1759000 tons, down 9.09% on a month on month basis, up 2.51% on a year-on-year basis.

The weldability of A131 grade D ship repairing steel is good. It means that under certain process and construction conditions, A131 grade D ship repairing steel 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.
