JIS G3445 STKM12A seamless steel pipe is mainly used to produce high-precision steel pipe materials. It has the advantages of no oxide layer on the inner and outer walls, high pressure without leakage, high precision, high finish, cold bending without deformation, expansion, flattening without cracks, etc. Therefore, it is very suitable for the production of pneumatic or hydraulic components, such as cylinders or oil cylinders.
JIS G3445 STKM12A seamless precision steel pipe has an outer diameter between 8mm and 219mm, a wall thickness between 1mm and 12mm, and a length that can be customized according to customer needs.
