12mm thick JIS SMA400BP strip

JIS SMA400BP strip,Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team It is a professional production team combining theory and practice With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel,JIS SMA400BP strip.

API 5L X42 steel plate (L290) is pipeline steel. API 5L X42 steel yield strength is 290 - 495 MPA, and the yield ratio is not more than 0.9. The JIS SMA400BP strip delivery status of API 5L X42 steel plate is hot rolling or controlled rolling. API 5L X42 steel plate (L290) is mainly used for the production of oil and gas gathering and long-distance pipelines or coal and building material slurry pipelines, to serve for transportation of gas, water and oil in the natural gas industry.

Pressure vessel plates are used to manufacture pressure vessel equipment in petrochemical, gas separation and gas storage and transportation equipment It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance The general heat treatment of Q345R plate is hot rolling, controlled rolling, normalizing The impact temperature is normal temperature, 0 ° C, -20,JIS SMA400BP strip.

JIS SMA400BP strip,The steelmaking furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the internal quality of the steel.
