How to protect 38Cr2 EN 10083-3 steel from oxide iron skin
EN10028-2 P235GH steel plate is a non-alloy quality steel with high temperature performance, executive standard: EN10028-2. Steel number: 1.0345. 38Cr2 EN 10083-3 steel, P235GH pressure vessel steel has good plasticity, toughness, cold bending performance and welding performance. The P235GH presure vessel plate and sheets size, shape and allowable deviation of the steel plate should meet the requirements of EN10028-1 2007 + A1: 2009.
Special boiler steel is derived from carbon structural steel, 38Cr2 EN 10083-3 steel. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.
The steel plate cutting and processing instructions are as follows: steel plate cutting and steel plate cutting processing, as well as 38Cr2 EN 10083-3 steel steel plate zero cutting processing. There are semi-automatic flame cutting, fully automatic CNC cutting, laser cutting and water cutting. The thickness range of steel plate that can be cut is 20650mm. In terms of 38Cr2 EN 10083-3 steel steel plate cutting types, there are Q235B common plate, Q345B low alloy plate and 45 carbon bonded plate.
The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, 38Cr2 EN 10083-3 steel and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, 38Cr2 EN 10083-3 steel sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
