316L stainless steel seamless tube :


The stainless steel seamless pipe is a long strip of steel with a hollow section and no seams around it. Stainless steel seamless tube

Stainless steel seamless tube features:


First, the thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the higher the processing cost will be. Secondly, the process of the product determines its limited performance. The seamless steel tube has low precision: uneven wall thickness, low brightness inside and outside the tube, high fixed-length cost, and pitting and black spots on the inner and outer surfaces are not easy to remove; thirdly, its detection and shaping must be processed offline. Therefore, it embodies its superiority in high-pressure, high-strength, mechanical structural materials.


Type of stainless steel tube:


The rolling method is divided into hot rolling, hot extrusion and cold drawing (rolling) stainless steel tubes.

According to the stainless steel metallographic structure, it is divided into semi-ferritic semi-Martensitic stainless steel pipes, martensitic stainless steel pipes, austenitic stainless steel pipes, austenitic-ferritic iron stainless steel pipes.

  

316L stainless steel seamless tube Grading and craft:


Surface grade


430 stainless steel has the following conditions, the status is different, and the dirt resistance and corrosion resistance are also different.

NO.1, 1D, 2D, 2B, N0.4, HL, BA, Mirror, and various other surface treatment states.


Feature processing


1D—The surface has discontinuous granules, also known as matte surfaces. Processing technology: hot rolling + annealing shot pickling + cold rolling + annealing pickling.


2D - a slightly shiny silvery white. Processing technology: hot rolling + annealing shot pickling + cold rolling + annealing pickling.


2B—Silver white and better gloss and flatness than 2D surfaces. Processing technology: hot rolling + annealing shot pickling + cold rolling + annealing pickling + quenching and rolling.


BA—The surface gloss is excellent and has a high reflectivity, like the mirror surface. Processing technology: hot rolling + annealing shot pickling + cold rolling + annealing pickling + surface polishing + temper rolling.


No.3—There is a good gloss and the surface is rough. Processing: Polishing and temper rolling for 2D or 2B with 100~120 abrasive (JIS R6002).


No.4—There is a good gloss and a fine grain on the surface. Processing: Polishing and temper rolling for 2D or 2B with 150~180 abrasive (JIS R6002).


HL - silvery gray with hairline stripes. Processing: Polishing the 2D or 2B with an appropriate size of abrasive material to continuously polish the surface.

MIRRO—mirror state. Processing: Grinding and polishing the 2D or 2B with the appropriate size of the abrasive material to the mirror effect.
