GB 309 ERW 1.4306 Seamless Stainless Steel Tubes
309 stainless seamless steel pipe industry tube
Stainless steel seamless pipe is a long steel with a hollow cross-section and no seams around it.
The thicker the wall thickness of this product, the more economical and practical it will be,
and the thinner the wall thickness, the greater the processing cost.
The process of this product determines its limited performance.
Generally, the precision of seamless seamless steel tubes is low:
uneven wall thickness, low brightness on the inside and outside of the tube,
and high cost of sizing, and there are pitting and black spots on the inside and outside.
Shaping must be handled offline.
Therefore, it embodies its superiority in high-pressure, high-strength, mechanical structural materials.
