With the development of China's 1 inch sa573gr.70 market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of 1 inch sa573gr.70 products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.
The ASTM A572 1 inch sa573gr.70 specification refers to high-strength low-alloy steel plates used in structural buildings. Among the five steel grades 42, 50, 55, 60 and 65, grade 50 is the most common in applications requiring higher strength and lighter weight. One of the 1 inch sa573gr.70 steels, the steel plate of this brand other than ordinary carbon steel is used, so that the steel structure has the same steel strength, but the weight is lighter.
The wear-resistant layer of 1 inch sa573gr.70 wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy 1 inch sa573gr.70 carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
The 1 inch sa573gr.70, wear resistant steel plate is composed of low carbon steel plate and alloy wear-resistant layer, and the alloy wear-resistant layer is 1/3 ~ 1/2 of the total thickness. The alloy wear-resistant layer and the base plate are metallurgically bonded. When working, the base plate provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.
The carbon content of 1 inch sa573gr.70, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our 1 inch sa573gr.70 products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our 1 inch sa573gr.70 service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's 1 inch sa573gr.70 customer service to establish a good, comprehensive, full service system.
