The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, quote for corrosion resistant steel Q355GNH seamless steel pipes for ships and petroleum cracking quote for corrosion resistant steel Q355GNH steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many quote for corrosion resistant steel Q355GNH products have been exported to the Middle East, India, Southeast Asia and Europe and America.
Automobile steel plates are mainly used to manufacture automobile beams (longitudinal and transverse beams), frame and other structural parts. Automobile beams not only have to withstand heavy static loads, but also withstand certain impacts, vibrations. Therefore, quote for corrosion resistant steel Q355GNH, automobile steel has certain strength and fatigue resistance, and require good stamping performance and cold bending performance to suit cold punching molding processing requirements.
The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as quote for corrosion resistant steel Q355GNH, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.
The hardness and impact toughness of precipitation-strengthened wear plates, quote for corrosion resistant steel Q355GNH are also improved. For example, the hardness of the wear-resistant plate after precipitation strengthening is 230-300 HBW, and the impact toughness is 140-180. More importantly, the improvement of the above indicators does not bring about a significant decrease in plasticity. The performance of the wear-resistant plate after water quenching at 1100℃, first holding at different temperatures in the middle temperature zone, and then water quenching at 970℃. With the increase of the holding temperature in the middle temperature zone and the extension of the holding time, the number of carbides in the steel increases, and the precipitation strengthening effect increases, resulting in an increase in hardness.
There are a lot of ASTM standards for pressure vessel steel plates. Such as ASTM A204, A285, A302, A387, A515, A516, A517, A537, A612, A841, etc. Those ASTM steel plates have different thickness ranges. quote for corrosion resistant steel Q355GNH, ASTM A204 plates shall not thicker than 150mm. ASTM A285 plates shall not thicker than 50mm. ASTM A515 plates shall not thicker than 200mm. ASTM A517 plates and A537 plates shall not thicker than 150mm. ASTM A612 plates shall not thicker than 25mm. ASTM A841 plates shall not thicker than 100mm.
