The hot rolling technolodge of LR DH40 shipbuilding steel plates

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for LR DH40 shipbuilding steel plates various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several LR DH40 shipbuilding steel plates after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

Low alloy steel Q345E angle steel bar can be composed of various stress-bearing components according to the different needs of the structure, and can also be used as a connecting piece between the components. LR DH40 shipbuilding steel plates, Q345E angle steel is widely used in various building structures and engineering structures, such as house beams, bridges, power transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.

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 LR DH40 shipbuilding steel plates product workpiece, thereby improving the production efficiency and production processing quality.

Pressure vessel steel plates are mainly used for manufacturing pressure vessels and other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of pressure vessel steel plates ranges from normal pressure to 320kg / cm2 or even 630kg / cm2, and the temperature ranges from - 20 °C to 450 °C. In addition to certain strength, good plasticity and toughness, pressure vessel steel plates must also have good cold bending and welding properties. Q245R, Q345R, 14Cr1MoR, 15CrMoR, LR DH40 shipbuilding steel plates etc. are common pressure vessel steel grades.

Due to the surge in business volume in recent years. In addition to coordinating our own truck fleet, our logistics department has continuously developed high-quality logistics companies and signed long-term cooperation agreements. While enjoying the professional and fast service of logistics companies, we have significantly reduced transportation costs. That not only ensure our customers receive the goods at the same time, but also help them reduce shipping costs.

The high strength LR DH40 shipbuilding steel plates low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of LR DH40 shipbuilding steel plates ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
