The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep ASTM A709 bridge steel plate processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and ASTM A709 bridge steel plate steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.
After heat treatment and cold drawing hardening, 65Mn steel has higher strength, certain toughness and plasticity; under the same surface state and complete hardening, the fatigue limit is equivalent to that of alloy springs. However, due to poor hardenability, it is mainly used for springs of ASTM A709 bridge steel plate smaller sizes, such as pressure regulating springs, force measuring springs, round and square spiral springs on general machinery or drawn into steel wires as springs on small machinery.
ASTM A709 bridge steel plate, High-strength wear-resistant plates have outstanding performance advantages. First of all, the high-strength wear-resistant plates get their name because their wear resistance is very good, and the degree of wear will not be prominent. Secondly, the corrosion resistance of the high-strength wear-resistant plate is very good. General chemical plants have many corrosive liquids, and the high-strength wear-resistant plates can be used as the floor to reduce risk of accidents.
The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the ASTM A709 bridge steel plate product workpiece, thereby improving the production efficiency and production processing quality.
