Influence factors of copper brittleness defects in denisty of 09CuPCrNi-B

Hot-rolled denisty of 09CUPCRNI-B 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, denisty of 09CUPCRNI-B corrosion-resistant steel plate, composite steel plate, pipeline steel plates, oil tank steel and alloy steel plate.

Weathering steel plate denisty of 09CUPCRNI-B for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate denisty of 09CUPCRNI-B has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.

S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the denisty of 09CUPCRNI-B rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of denisty of 09CUPCRNI-B steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.

Expect in the denisty of 09CUPCRNI-B goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen denisty of 09CUPCRNI-B product development technology, excellent production team, hand strict quality control, sales and after-sales service.
