The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel 16Mo3 grade products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the 16mo3 grade market and has strong competitiveness.

The properties of 16mo3 grade ASTM A36 steel allow it to deform steadily when the stress increase exceeds the yield strength. This ductility enables the building to stand still after meeting the structural limit in an emergency. Other 16mo3 grade high-performance steel, such as bridge strand, has very strong strength and brittleness, and its deformation is minimum before severe fracture of bridge strand.

Bridge steel plates are thick steel plates made of carbon steel and low-alloy steel for bridge construction. The main applications of bridge steel plates are to build railway bridges, highway bridges, and sea-crossing bridges. The bridge steel plates are required to have high strength, durability and bear the load and impact of rolling stock. Bridge steel plates have good water resistance, low thermal conductivity, flat and lubricated surface. The main grades of bridge steel plates are A709 grade 50, A588 grade B, 16mo3 grade and so on.

16mo3 grade, S355j2g3 steel plate is a kind of main atmospheric corrosion-resistant steel, s355j2g1w steel plate is a kind of weathering structural steel, its mechanical properties are similar to s355j2g2. By adding CR, Cu and Ni, the oxide layer is firmly attached to the workpiece surface. This oxide layer prevents further corrosion of the steel.

SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. 16mo3 grade, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.

Our company stocks a wide range of hot rolled carbon steel plate distributed globally from our service centers in the U.S., Canada, Mexico, U.K, France, Shanghai, and Singapore. Customers calling for 16mo3 grade A516 a lot of times are also trying to get their arms around forecast issues. As our customers continue to work on their forecasts, IRON & Steel has options to help you conduct structured forecast reviews and put inventory strategies in place to effectively manage any impact from forecast variability.

Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
