DIN2391 St30Ai high-precision seamless steel pipe is made of high-quality carbon steel, precision drawn, non-oxidizing bright heat treatment (NBK state). The inner wall of the steel pipe is brushed with special equipment and washed under high pressure. The steel pipe is covered with anti-rust oil for rust prevention and the two ends are sealed for dust prevention.
The main features of DIN2391 St30Ai seamless precision steel pipe are: high precision, good finish, good inner wall cleanliness, steel pipe can withstand high pressure, no deformation after cold bending, no cracks after expansion and flattening, and can be subjected to various complex deformation and mechanical processing.
