Detailed Parameters

Synopsis of Seamless Stainless Steel:

Seamless stainless steel pipe is a kind of long steel with hollow section and no joints around it. The thicker the thickness of the product is, the more economical and practical it is. The thinner the wall thickness, the greater the processing cost will be.

The technology of this product determines its limited performance, the general seamless steel pipe is of low precision, the wall thickness is not uniform, the exterior and exterior light brightness is low, the cost of the fixed length is high, and the internal and external table, and the black spot is not easy to be removed; its detection and shaping must be processed off-line. Therefore, it manifests its superiority in high pressure, high strength and mechanical structure.

Features of Seamless Stainless Steel Pipe:

1) Treatment: Hot Rolled and Cold Rolled

2) Seamless Stainless Steel Normal Material Grade: 200/300/400 series

3) Surface:Picking,Polished/Satin/Hairline:180G/320G/400G etc.,Mirror Finish:400G/500G or 800G

4)WallThickness Range: 1mm~30mm

5) Edge: Slit edge & Mill edge

6)Outdiameter Range: 6 - 630mm

7)LengthRange: 6m or as your request

8) Available Standard: ASTM, AISI, SUS, JIS, EN, DIN, GB, ASME, etc.

In general, ASTM A240/A240M or as your requirements

9) Certification: MTC and SGS and Any third party inspection 

10) Package: Standard Export Sea-Package (Waterproof Kraft Paper + Wooden Pallet + Bundle with steel strip)

Advantages Of Seamless Stainless Pipe:

1.)High economic

2.)High practical

3.) Excellent corrosiveness

4.) Widely used in industry
