The company is a leading company that sells hot rolled RA 40 hull steel plate steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold hot rolled RA 40 hull steel plate steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.
HARDOX steel hot rolled RA 40 hull steel plate is a famous wear-resistant steel brand. It is designated as Hardox400, hardox450, hardox500, hardox600. It has good wear resistance in general and special applications.
If a destructive accident occurs during the use of the boiler, it will cause serious losses. Therefore, other than some common strengths with hot rolled RA 40 hull steel plate, the boiler steel plate must have good physical properties, mechanical properties and workability, and be strictly specified in the technical terms of the material standard to meet its safety in use. High temperature (above creep temperature) boiler steel plates are generally low-alloy heat-resistant steels, such as chromium molybdenum steel, chromium molybdenum vanadium steel, chromium molybdenum tungsten steel, etc.
The preparation of hot rolled RA 40 hull steel plate galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for hot rolled RA 40 hull steel plate centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. hot rolled RA 40 hull steel plate, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
