With high-quality RINA AH32 collision bulkhead steel steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our RINA AH32 collision bulkhead steel steel market and improved the control of steel plate production quality.
The predecessor of Ningbo port is Ningbo Port Authority. Ningbo port consists of Beilun port, Zhenhai port, Ningbo port, Daxie port and Chuanshan port. It is a multi-functional and comprehensive modern deep-water port integrating inland river port, estuary port and seaport.
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 RINA AH32 collision bulkhead steel are higher than that of annealed RINA AH32 collision bulkhead steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of RINA AH32 collision bulkhead steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.
The Indonesia INKA is the only train carriage maker for railway industry in Indonesia. We cooperated with them since 2012 and supply them SPA-H steel. The SPA-H steel is used by them to fabricate train carriage. We have huge stocks for SPA-H steel and can arrange delivery for them in short time after receiving order. Meanwhile, our product RINA AH32 collision bulkhead steel quality has passed their test for so many times use. Therefore, they trust us and give us repeat orders regularly. And we also do our best to support them and have never let them down though past cooperations.
A131 EH36 steel is high strength marine grade hull structural steel. Its yield strength is no less than 355Mpa, tensile strength is 490-620 Mpa, and elongation is 19% min. RINA AH32 collision bulkhead steel, EH36 steel strength is close to S355 steel. However, EH36 steel is shipbuilding steel, while S355 steel is carbon structural steel, and can not be certified by classification society. That is to say, S355 steel is not allowed to be used for ship building when there is certificate requirement. A131 EH36 steel is widely used to build ships working in low temperature water.
