The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating A588 Gr K structural steel plate production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.
In our impression, stainless steel, as the name implies, will not rust, which is why many people choose stainless steel. Stainless steel has beautiful appearance, corrosion resistance, wear resistance, high strength, so it has a certain charm. In the past few decades, A588 Gr K structural steel plate, stainless steel has been widely used in all aspects of industry and daily life. Under normal conditions, stainless steel will not rust. Improper use, such as long-term exposure to seafood and other salt environment, stainless steel surface will also occur corrosion.
The main advantage of weather resistant steel plate is its weathering ability. When exposed to the atmosphere, the weather resistant steel plate will form a anti-corrosion film on the surface, and prevent further corrosion to the steel A588 Gr K structural steel plate. Thus the weather resistant steel plate almost needs no paint treatment, which is the important measure for carbon steel plates to avoid going rust. Therefore, the maintance cost of weather resistant steel plate is low. The weather resistant steel plate is suitable for outside structure and construction use.
Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched A588 Gr K structural steel plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of A588 Gr K structural steel plate during tempering, while tempering determines the performance and life of the workpiece.
20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. A588 Gr K structural steel plate, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.
Our company will accept the product quality objection registration record, pass it to the A588 Gr K structural steel plate production unit and relevant departments, and timely coordinate the supervision of product A588 Gr K structural steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
