Recently, Openex provided a turnkey service for an aerospace technology project for a regular customer with our "one-stop metalworking" service.
The products of this project involve multiple material grades of stainless steel and carbon steel with various specifications, complicated drawing numbers and processes, and strict dimensional accuracy. During the processing, we successfully completed the whole process from material leveling, cutting, oil grinding, and edge milling to plate rolling with the advantage of advanced equipment and techniques.
The steel plate is a flat steel that is poured with molten steel and pressed after cooling. Medium-thick plate refers to a steel plate with a thickness of 4.5-25.0mm, a thickness of 25.0-100.0mm is called thick plate, and the thickness over 100.0mm is extra thick plate.
Medium-thickness plate generally has high comprehensive mechanical properties. Mechanical properties required are strength, plasticity, hardness, impact toughness, stiffness, etc. Process performance requirements are welding performance, hardenability, processability, weather resistance, corrosion resistance, wear resistance, fatigue resistance, high-temperature characteristics, and low-temperature characteristics. corrosion resistance, wear resistance, fatigue resistance, high-temperature characteristics, low-temperature characteristics, etc.
Medium thick plate can be cut and combined according to the requirements of use, made into various structural parts and mechanical parts, can also be made into welded steel, further expanding the use of steel plate; can be bent and stamping forming, made into boilers, containers, punching car shells, civil utensils, appliances, can also be used as a welded steel pipe, cold-formed steel billet.
Medium thick plate is mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, etc.. It can also be used to manufacture various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low-alloy steel plates, shipbuilding steel plates, boiler steel plates, pressure vessel steel plates, pattern steel plates, automobile beam steel plates, tractor parts and welded components, etc.
Such industries as shipbuilding, construction, and mechanical engineering consume most thick plates. Each of the above segments sets its own requirements for steel plates, which can be unique. Some steels can be certified according to two standards at a time: shipbuilding and construction. For example, structural steel S355J2 can be made and rolled so that its chemical composition and mechanical properties fully correspond to shipbuilding steel grade А32. However, there are steel grades that differ in their chemical composition, physical and mechanical properties, and delivery conditions. For example, good weldability of thick plates is crucial for the construction sector, while abrasion resistance is needed for some applications in the engineering industry.
Some applications of steel plate require additional finishing and processing like leveling, Cutting, Plate Edge Milling, Rolling, Bending, drilling and more.
