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 SA573 Grade 70 steel for marine engineering processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and SA573 Grade 70 steel for marine engineering steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

We have strong strength of steel plate production, high-quality products, and low prices. Guarantee to thank the new and old customers for their trust with good products, excellent quality, low price and perfect service. The company provides customers with professional "one-stop" logistics services: warehousing, loading and unloading, and transporting. The perfect logistics management, facilities, network and guarantee system guarantee customers' worry-free delivery.

The user of S355NC grade must make sure that his calculation, design and processing methods are appropriate for the SA573 Grade 70 steel for marine engineering material. The forming process used must be suitable for the intended application and comply with the state-ofthe- art; it is of fundamental importance to the processing behaviour of this SA573 Grade 70 steel for marine engineering steel grade.

In April 8th, 2018, our Philiphine customer purchased 1008 Tons API 5L Gr.B ERW pipes &Q345B seamless steel pipe for offshore oildfield resources drilling project. This is a regular demand almost every two month, and we has been cooperated more than three times, totally around 2100 tons API 5L Gr.B steel pipeline since 2015 year. We can supply the relative certificated for the API 5L Gr.B ERW pipes products like SGS report, B/L &Form M, and mill test certificate.

The difference between SA573 Grade 70 steel for marine engineering, 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%.

The formula of enterprise success is: success = strategy × organizational capability, that is, having the right direction and strong organizational capability. The core competence of an enterprise depends on three pillars: first, talents (talent echelon); second, core values of enterprise culture; third, organizational governance model. If the enterprise is a tree, then the core values of talents, corporate culture and organizational governance mode are just like the root of the tree. With them, the enterprise will flourish and grow forever.
