The RINA AH40 marine steel sheet weathering steel plates are our main products, which are also called weather resistant steel plates, corten steel plates, atmosphere corrosion resistant steel plate, anti-corrosion plates, etc. The main recognized standards for weathering steel plates are ASTM CORTEN, ASTM A588/A588M, ASME SA588/SA588M, EN 10025-5, EN 10155, TBT 1979, GBT 4171, JIS G 3114, JIS G3125, ASTM A242/A242M, etc. Our typical weathering steel grades are Corten A, A588 grade B, S355J2WP, S355J0WP, 09CuPCrNi-A, 05CuPCrNi, Q355NH, SPA-H, A242 type 1, etc.
Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, RINA AH40 marine steel sheet quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the RINA AH40 marine steel sheet International leading steel materials supplier.
The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for RINA AH40 marine steel sheet pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common RINA AH40 marine steel sheet carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
Water cutting machine is called water knife for short, that is, water is used as knife. High pressure water jet cutting technology can perform any curve cutting process on any material, RINA AH40 marine steel sheet included. The heat generated in the cutting process will be immediately taken away by the water jet without harm. Material, no need or easy to reprocess after cutting, safety and environmental protection, faster, faster, more efficient.
The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
