With a strong focus on quality, cutting-edge production facilities, and adherence to international standards, Dang Steel serves both local and global markets. Drawing on years of experience in the steel industry, the company offers tailored solutions to meet a variety of industrial needs. Their Q and T 700 steel products are perfect for demanding structural applications that require exceptional strength, durability, and performance in extreme conditions. Plus, Dang Steel guarantees timely delivery and competitive pricing.
Q and T 700 steel sheets and plates are robust, quenched and tempered structural steels boasting a minimum yield strength of 700 MPa. Their typical chemical makeup features carbon (0.20-0.25%), manganese (1.0-1.6%), silicon (0.2-0.5%), along with chromium, nickel, and molybdenum to enhance toughness and weldability. The mechanical properties include impressive tensile strength (900–1050 MPa), good elongation (≥14%), and outstanding impact resistance even at low temperatures. These traits make Q and T 700 an excellent choice for applications that demand high load-bearing capacity without sacrificing toughness or fatigue strength.
