What is the difference between hardox 450 steel grade and medium thick plate

Based on the principle of quality and respect for customers, BBNsteel maintains good cooperative relations with customers in home and abroad. With modern management, high-quality products, reasonable prices and comprehensive after-sales service, we provide our customers with high quality and low price Hardox 450 steel grade products.

ASME SA516 GRADE 70 boiler steel plates are of the best quality and are, therefore, one of the most preferred steel grades in the market. It is remarkably resistant to corrosion and deterioration and also repellent to erosion and thus is convenient to be used in various conditions. These plates Hardox 450 steel grade are primarily intended for use in conditions wherein supreme strength and durability are required. These ASME SA516 GR 70 plates offer the highest yield and tensile strength range. And, the boiler quality plates offer the highest utility and are also exceptionally reliable.

Unlike general steel manufactures, other than regular fresh production, we also have huge stocks. What is more, we offer cutting, welding, drilling, bending, etc. deep processing for the steel materials. That enable us to meets various Hardox 450 steel grade steel sizes and shapes requirements of clients.So, if you have any steel demands, or steel processing needs, please do not hesitate to contact with us. We will try our best to make you stisfied.

Hardox 450 steel grade, Q345B low alloy steel plate composition: 1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%; 2) Add manganese-based alloying elements; 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel; In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.
