At present, the company has successfully developed and produced more than 10 kinds of boron-containing steel varieties such as 35MnBM, 23MnBM, A709 grade 100 bridge steel plate, 27MnTiB, 40MnB, 25CrMoTi, etc. According to the practice of Laiwu Steel's 50t electric arc furnace-50t LF-60t VD-R11 Lianzhuo-VD Royal alloying process development and production of boron-containing steel, the technical measures for precise control of the smelting of boron-containing steel are analyzed and discussed.
In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel A709 grade 100 bridge steel plate surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.
Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium A709 grade 100 bridge steel plate carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some A709 grade 100 bridge steel plate alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s A709 grade 100 bridge steel plate domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
