EH500 steel plates and EH550 steel plates are both ultra-high-strength structural steel plates for ships and oceans. The addition of microalloying elements can not only improve the strength, compensate for the strength loss caused by the reduction of carbon equivalent, but also improve the welding performance, mechanical properties and process performance of the steel LR grade D seafaring ship steel. Due to the use environment requirements of EH500 steel plate and EH550 steel plate, it can meet the requirements of high strength, high toughness, high welding performance, and thickness direction performance.
LR grade D seafaring ship steel, low alloy high strength steel has good weldability. Welding is the most common method to construct engineering structure, so the steel used in engineering structure requires good welding performance. Low alloy high strength steel has low carbon content, low alloy element content and good plasticity, so it is not easy to produce quenching structure and crack in the weld area, and the addition of Ti, Nb, V can also inhibit the grain growth in the weld area. Therefore, most of the low alloy high strength steels have excellent welding performance and no heat treatment is required after welding.
We do sand blasting and shop primer for various LR grade D seafaring ship steel steel plates such as carbon steel plates, high strength low alloy steel plates, shipbuilding steel plates, etc. before delivery, so as to protect the steel plates from going rust during transportation. Our sand blasting standard is SA2.5, and shop primer LR grade D seafaring ship steel thickness is 20μm or so. Our shop primer has been certified by ABS, LR, BV etc. authorities.
Welcome customers to visit our company, we specialize in steel products, adhere to the LR grade D seafaring ship steel quality first standard, and do not forget to provide customers with the best quality products and services. Our product quality office is the best, and our LR grade D seafaring ship steel price is also very advantageous. Welcome to purchase steel products from our company.
Our company will accept the product quality objection registration record, pass it to the LR grade D seafaring ship steel production unit and relevant departments, and timely coordinate the supervision of product LR grade D seafaring ship steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
