Ultrasonic testing principle of S690QL mechanical properties

Although Q345E steel plate has stronger torsion resistance and better corrosion resistance than ordinary steel plate, there are still some environments that can cause corrosion to Q345E steel plate. The following environment should be avoided as far as possible to avoid corrosion of S690QL mechanical properties, Q345E steel plate. 1. Acid water. 2. Salt water. 3. Nitric acid. 4. Atmospheric erosion. Atmospheric erosion for Q345E steel plate corrosion is reflected in the chloride and pollutant pollution source of Q345E steel plate corrosion, this corrosion is very serious.

The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the S690QL mechanical properties industry, keep pace with the times, and move towards a new course!

The wear-resistant plate has the main advantages of high strength and hardness, good toughness, S690QL mechanical properties high tensile strength, good material wear-resistance, long service life and low cost. In order to verify the wear-resistant life of the high wear-resistant composite steel plate applied in the field, the comparative industrial test of S690QL mechanical properties wear-resistant with the ordinary carbon plate was carried out on the reclaimer of Jigang raw material plant, and the effect is good.

The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The S690QL mechanical properties, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.

The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, S690QL mechanical properties deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world. The company has won widespread praise from customers.
