The SA 516 grade 60 steel is remarkably one of the standard steel grades having five chemical elements that are specified with the three mechanical properties. The grade does not require to be heat treated; hence it offers the best properties and features. Our aim is to provide our customers with a high quality of theA709 Gr HPS50W bridge steel plate product which has all the qualities that an application requires for working. The SA 516 grade 70 plates are widely used in different applications because of its easy to use and installation process.
With the development of China's A709 Gr HPS50W bridge steel plate 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 A709 Gr HPS50W bridge steel plate products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.
Cold rolled A709 Gr HPS50W bridge steel plate steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner A709 Gr HPS50W bridge steel plate steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet
The allowable temperature of A709 Gr HPS50W bridge steel plate, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of A709 Gr HPS50W bridge steel plate work, the actual stress of A709 Gr HPS50W bridge steel plate under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of A709 Gr HPS50W bridge steel plate under the temperature.
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 A709 Gr HPS50W bridge steel plate 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 A709 Gr HPS50W bridge steel plate customer service to establish a good, comprehensive, full service system.
