Do you know the 5mm thickness stanag 4569 1 steel hardness?

The 5mm thickness STANAG 4569 1 steel plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The 5mm thickness STANAG 4569 1 steel products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate 5mm thickness STANAG 4569 1 steel has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.

10# seamless steel pipe chemical composition : C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. 10# seamless steel pipe mechanical properties: recommended heat treatment temperature: 930℃, tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%, impact energy is not required. 5mm thickness STANAG 4569 1 steel, 10# seamless steel pipe has high plasticity and toughness, no temper brittleness tendency, and good weldability. Its machinability under cold drawing or normalizing treatment is obviously improved. In cold state, 10# seamless steel pipe is easy to be extruded and molded, but its strength is low, and its hardenability is very poor.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
