What are the top 3 EN10083-3 alloy steel 34crmo4 steel equivalent hot rolled plates mills in UAE
Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, EN10083-3 alloy steel 34crmo4 steel equivalent based on a high starting point and high technology, the company has vigorously developed various steel products EN10083-3 alloy steel 34crmo4 steel equivalent and deep-processed parts, steel structures, precision castings, seamless pipes.
35CrMoA steel has high static strength, impact toughness and higher fatigue limit, higher hardenability than 40Cr, high creep strength and endurance strength at high temperature, long-term working temperature can reach 500℃; plasticity during cold deformation Medium, poor weldability. Alloy steel EN10083-3 alloy steel 34crmo4 steel equivalent is used as important structural parts that work under high loads, such as transmission parts of vehicles and engines; rotors, main shafts, heavy-load transmission shafts of steam turbine generators, and large-section parts.
The Performance requirements of low alloy structural steel, EN10083-3 alloy steel 34crmo4 steel equivalent:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.
The effect of nitrogen (N) on the properties of EN10083-3 alloy steel 34crmo4 steel equivalent and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in EN10083-3 alloy steel 34crmo4 steel equivalent and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. EN10083-3 alloy steel 34crmo4 steel equivalent, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.
