Marine steel plates are classified as medium-thick plates, hot-rolled steel plates used for manufacturing hull structures produced in accordance with the requirements of the classification society. First, the toughness of the marine steel ABS Grade A, EN 10025 S355M steel plates, ABS EH36 plate is the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.
The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep EN 10025 S355M steel plates processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and EN 10025 S355M steel plates steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized EN 10025 S355M steel plates are higher than that of annealed EN 10025 S355M steel plates, but the elimination of internal stress is not as good as annealing. The normalizing operation of EN 10025 S355M steel plates is simple, the cost is low, the productivity is high, and it is widely used in actual production.
When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the EN 10025 S355M steel plates, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.
The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
