We have S460nl VS S460ML new cooperation projects with NNPC (Nigerian National Petroleum Corporation). Through tender, we got new order about oil tank plates for NNPC, and the tank plates will be used to build large oil tanks. This is not the first time we cooperated with NNPC, but it means much more to us than first time cooperation. It indicates our S460nl VS S460ML tank plates quality has been well recognized by Nigeria market.

We can process the steel materials according to your drawing. Or if you can not make drawing, please send us S460nl VS S460ML specific data and requirements, our technical department can make design and drawing for you, and then confirm with your technician or engineer.

The difference between S460nl VS S460ML, Q420D steel and Q460D steel: Q420D steel has good mechanical properties and weldability, good cold and hot workability. Q420D steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts. S460nl VS S460ML, Q460D steel has high strength, good plasticity and toughness, good weldability and good cold and hot workability. Q460D steel is mainly used for manufacturing engineering machinery components, such as mining machinery, forklift truck, transport vehicle, bridge, medium and high pressure boiler and other large-scale welding structural parts.

SA537 grade 70 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the S460nl VS S460ML, SA537 grade 70 steel coil thickness should not exceed 25 mm. The mechanical properties of SA537 grade 70 steel is yield strength is 290MPa, and the tensile strength is 485-620Mpa.

In 2018, one of our India customers visit Zhengzhou office building and work shop to discuss carbon steel Q235B grind plate technical request. They have strict surface and thickness tolerance, and they also request UT and MT for testing for Q235B grind plate. As a result, they purchase 179 tons as trial order for first cooperation. After using the gind plate, the India customer has good comment on our S460nl VS S460ML quality. Till now, we keep exporting around 100 tons per month as regularly.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate S460nl VS S460ML EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
