What is the q355gnh hull structure steel price export to Russia

In today's q355gnh hull structure steel steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of q355gnh hull structure steel market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

Hot-rolled q355gnh hull structure steel steel plate mill operates heavy plate cutting, galvanized steel plate, steel plate punching, hot-rolled steel plate manufacturing, spring steel plate, 35crmo steel plate, 40cr steel plate, Q345C steel plate, 12cr1mov alloy plate, 16mn steel plate, A573 grade 70 pressure vessel plate, 15crmo alloy Steel plate, A516 grade 70 boiler plate, bridge structure steel plate, q355gnh hull structure steel corrosion-resistant steel plate, composite steel plate, pipeline steel plates, oil tank steel and alloy steel plate.

Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The q355gnh hull structure steel metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other q355gnh hull structure steel alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary q355gnh hull structure steel carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.

Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, q355gnh hull structure steel included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.

The chemical composition difference between q355gnh hull structure steel, Q235B and 20# steel is as follows:
The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%.
The difference of mechanical properties between q355gnh hull structure steel, Q235B and 20# steel is as follows:
The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
