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 ship construction use A131 AH32 structural steel processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and ship construction use A131 AH32 structural steel steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.
BBN company is a modern enterprise integrating steel producing, warehousing and logistics, processing and distribution. We are committed to creating a "one-stop steel procurement service" platform. The main products are I-beam, angle steel, ship construction use A131 AH32 structural steel , H-beam, hot-rolled coil, welded pipe, spiral pipe seamless pipe and many other steel products. Standing stocks amount to more than 30,000 tons, and complete specifications, the company gradually moves towards large-scale distribution enterprises with serialized products, standardized services and modern transportation management.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the ship construction use A131 AH32 structural steel quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After ship construction use A131 AH32 structural steel quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
ANDRITZ GROUP is the world's leading industrial group, with 29500 employees and more than 280 branches in more than 40 countries. We have cooperated with their Mexico company for many years about S355J2+N steel plates and cutting sectors. The S355J2+N steel plates ship construction use A131 AH32 structural steel need to cut according to the drawing by standard tolerance, UT, MT and dimension request. The final application of the S355J2+N steel plates and cutting sectors are for assembling hydraulic machine.
The difference between ship construction use A131 AH32 structural steel, 10# seamless steel pipe and 20# seamless steel pipe: 1. Chemical composition Chemical composition of 10# seamless steel pipe: C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. Chemical composition of 20# seamless steel pipe: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25 2. Mechanical properties 10# seamless steel pipe: tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%. 20# seamless steel pipe: tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%.
Our vasion is to create a first-class steel plate manufacturing enterprise with international competitiveness. Business Vision: Improve value with quality and become the leader in the industry. Core values: people-oriented, integrity, responsibility, excellence. Development strategy: Seek development through science and technology, and seek benefits from management.
