DIN 2391 ST37 seamless steel pipes supplied by GNEE can withstand high pressure, and will not deform during cold bending, and will not crack during expansion and flattening. They can be subjected to various complex deformation and mechanical processing.
The outer diameter range of DIN 2391 ST37 seamless precision steel pipes is 16-325mm or 4-76mm. The wall thickness is usually 1-22mm or 0.5-6.0mm. It can be customized according to the specific needs of customers.
Common delivery states include NBK (bright oxygen-free normalizing) and others. In addition, there are other delivery states, such as NBK (+N), GBK (+A), BK (+C), BKW (+LC) and BKS (+SR).
DIN 2391 ST37 seamless cold-drawn steel pipes are widely used in hydraulic systems, automobile manufacturing, injection molding machines, hydraulic presses, ships, EVA foaming hydraulic machinery and other fields.
