The following thickness limitations are given in this EN 10225 weldable structural steel standard: — S355NLO up to and including 200 mm; — S355MLO, S420MLO, S460MLO, S500MLO up to and including 120 mm; — S420QLO, S460QLO, S500QLO, S550QLO, S620QLO, S690QLO up to and including 150 mm.
Accept the inquiry from the owner of the goods and the inquiry by sea: master the port and price from the port of shipment to all continents and routes, and the port and price that the owner often needs to serve; the shipping schedule information of the main shipping companies; when necessary, ask the owner of the inquiry for some category information, such as the name of the goods, the level of danger, etc. (water hazard code).
Chromium element (Cr element) can improve the strength and hardness of EH36 marine steel plate, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. eh36 marine steel plate, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.
