The whole plant covers an area of 18,480 square meters, a workshop area of 9,500 square meters, and a final assembly workshop of 4,300 square meters; fixed assets are 25.50 million yuan. The company has A283 Gr D CS steel carbon plate strong technical force, complete quality assurance system sophisticated tooling equipment and advanced technology. It can provide high efficiency professional equipment and A283 Gr D CS steel carbon plate pressure vessels for domestic and foreign chemical, petroleum, chemical, metallurgical, pharmaceutical, fertilizer, textile, and environmental protection industries.
The difference between A283 Gr D CS steel carbon plate, Q420D steel and Q460D steel: Q420D steel has good mechanical properties and weldability, good cold and hot workability. Q420D steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts. A283 Gr D CS steel carbon plate, Q460D steel has high strength, good plasticity and toughness, good weldability and good cold and hot workability. Q460D steel is mainly used for manufacturing engineering machinery components, such as mining machinery, forklift truck, transport vehicle, bridge, medium and high pressure boiler and other large-scale welding structural parts.
Q345R material is a special steel grade for pressure vessels with a yield strength of 340MPa. It has good comprehensive mechanical properties and technological performance. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 (16Mn) steel. In addition to the increased tensile strength and elongation requirements compared to Q345 (16Mn) steel, it also requires impact toughness. Q345R steel plate is currently the most widely used and most used steel plate for pressure vessels in China.
In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like A283 Gr D CS steel carbon plate, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.
Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. A283 Gr D CS steel carbon plate, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
