How to protect the hardox 400 steel yield strength
The HARDOX 400 steel yield strength 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 HARDOX 400 steel yield strength 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.
BS600MCJ4 steel is a hot rolling carbon low-alloy high strength steel. It is design by reducing the carbon equivalent of the steel and welding crack sensitivity index, and use of advanced smelting equipment and technology to strengthen the collection of micro-alloying technology, good weldability. We sincerely hope to establish long-term cooperation relationship with you on the basis of mutual benefit, reciprocity and common development for HARDOX 400 steel yield strength project.
Strip steel is coiled and curved steel plate, which is different from common steel pipes and steel plates. Strip steel has obvious characteristics. First, it is thin and easy to curl, which is convenient for logistics and transportation. Second, the surface quality of HARDOX 400 steel yield strength, strip steel is good, the luster is bright and it has good flexibility. Third, the strip steel is easy to process. When you need to use it, you only need to straighten the bent part and you can directly process it. Fourth, the precision is high, and the strip steel can be made of plain carbon steel, carbon structure steel, spring steel, tool steel, stainless steel, etc.
The microstructure of the quenched and tempered alloy steel, HARDOX 400 steel yield strength after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.
The quality grade of common carbon structural steel Q235 can be divided into A, B, C, D and E. Relatively, the quality of Q235A is poor and that of Q235E is the highest. Different grades of Q235 steel have different characteristics, which are mainly different from the impact temperature: Q235A does not require impact toughness test; grade Q235B is for room temperature (20℃); grade Q235C is for 0℃; grade Q235D is for - 20℃; grade Q235E is for - 40℃. The HARDOX 400 steel yield strength, carbon structural steel Q235 has good combination of strength, plasticity and welding properties.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate HARDOX 400 steel yield strength EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
