Austenitic Stainless Steel Round Tube Grade 304/304L 316/316L 321 316Ti 317L 347H 904L 254SMO

More than 20 years to manufacture and supply stainless steel tubing comply with ASTM A213/A269, ASTM A312, ASTM A789, EN 10216-5, DIN 17456, 17458 etc, dimension from DN6-DN600.

Pickled Surface Stainless Steel Tube (Mill Finish)

The mill finish of stainless stee tubings is pickled surface. The tubes will be pickled and passivated after solution annealing, then it will get a passivation coating to improve the performance of corrosion resistance. If there is no specific requirement on the surface, the tube will be mill finish.

Polished Stainless Steel Tube

The polished is mechanical polishing here, including internal surface and external surface. The roughness can be min. 0.4 µm (16 µin) or Grit 300 from polishing. Mechanical polishing uses a fully automatic polishing machine to control the surface accuracy and roughness to meet the needs of food grade and bioengineering.

Bright Annealing / BA Tube

BA tube is stainless steel tube with bright annealing, a heat treatment process that is different from ordinary solution annealing of stainless steel, and can obtain a better precision and surface roughness. The BA tube does not need to be pickled again, and its roughness can meet the precision requirements of polishing, but the cost is higher than mechanical polishing stainless steel tubes.

Electropolishing / EP Tube

Stainless steel EP tube is high purity and high-precision tube, which is mainly used in demanding environments such as bioengineering, semiconductors, laboratories, and precision instruments. Our EP pipe can reach a roughness of 0.2 on the inner surface to meet the stringent requirements of various working conditions.
