EN10305-4 E235 carbon steel pipe has improved the precision and finish of the steel pipe through cold drawing process and non-oxidation bright heat treatment (NBK state). After brushing and high-pressure flushing with special equipment, the inner wall is ensured to be clean.
EN10305-4 E235+N precision steel pipe supplied by GNEE has strong high pressure resistance, no deformation after cold bending, no cracks after flaring and flattening, and can undergo various complex deformation and mechanical processing. It is used in fields with high requirements for steel pipe precision, finish, cleanliness and mechanical properties.
