What does S275JR material mean?
The meaning of S275JR carbon steel pipe:
"S" represents structural steel;
"275" indicates the minimum yield strength (MPa) of steel with a thickness ≤16mm;
"JR" indicates the quality grade related to the Charpy impact energy value (27J, tested at room temperature 20℃);
1.0044 is the steel part number for S275JR.
What quality standards does S275JR black carbon steel pipe mainly meet?
S275JR black carbon steel pipe mainly meets the European non-alloy structural steel standard EN 10025-2.
What engineering fields is S275JR black carbon steel pipe suitable for?
S275JR black carbon steel pipe is suitable for general building, structural applications, and the oil and gas industry, especially for applications requiring moderate stress, good weldability, and structural support. It is also used in sewage systems and certain industrial applications, such as components for storage tanks and equipment supports.
How is corrosion protection treated on S275JR black carbon steel pipe?
The corrosion protection treatment of S275JR black carbon steel pipe first involves surface pretreatment, followed by coating with a protective coating such as 3PE (triple-layer polyethylene), FBE (fusion-bonded epoxy), or hot-dip galvanizing.
What is the pressure resistance of S275JR black carbon steel pipe?
The pressure resistance of S275JR black carbon steel pipe depends on its minimum yield strength of up to 275 MPa and its good tensile strength, making it suitable for medium and high pressure applications in structural and piping systems.
