Threaded flanges are widely demanded as pipe flanges i.e called as threaded pipe flanges used in different industrial applications.
Threaded Flanges are also known as screwed flange, and it is having a thread inside the flange bore which fits on the pipe with matching male thread on the pipe.
Raw materials of S275JR Threaede Flanges is a hot-rolled non alloy structural steel, and the executive standard is en10025-1. Jr indicates that there are no special requirements such as cold forming. The chemical composition requirements are C < = 0.21%, Mn < = 1.5%, si not required, P < = 0.045%, s < = 0.045%, n < = 0.009%, and the carbon equivalent of Raw materials of S275JR Threaede Flanges the general nominal thickness < = 40mm < = 0.40%. Mechanical properties of S275JR Threaede Flanges: yield strength > = 275mpa, tensile strength of S275JR Threaede Flanges 430-580mpa, elongation > = 14%. However, the European standard requirements of Raw materials of S275JR Threaede Flanges are more detailed, and the properties of different thicknesses are slightly different. See the standard for details.
This kind of of Raw materials of S275JR Threaede Flanges has been produced by our company. The five major elements can meet the requirements, and there is no need to add other alloys.
European standard steel, brand Raw materials of S275JR Threaede Flanges, which is equivalent to q295b steel of domestic standard, is a low alloy high-strength structural steel with good plasticity, welding performance and impact toughness. It also has good cold and hot processing performance and low and medium temperature performance, and has certain corrosion resistance. Raw materials of S275JR Threaede Flanges can be used for manufacturing stamping parts of vehicles, building structural parts, medium and low pressure chemical vessels and low pressure boiler drums, sheet metal stamping parts, oil pipelines, oil storage tanks and projects with low temperature requirements.
