316L stainless steel seamless pipe
Jaway steel is major manufacturing specialized in stainless steel wih high quality and best price! Which can be widely used in bicycle fittings, kitchen and sanitation tools, goods shelf, pet cages, gill racks, decorative handles and baskets, food and medical machinery accesses, etc.
316L stainless steel seamless pipe:
Classification of stainless steel pipes: two basic categories: stainless steel seamless steel pipe and stainless steel welded steel pipe (sewn steel pipe). According to the outer diameter shape of the steel pipe, it can be divided into a circular pipe and a special-shaped pipe. The circular steel pipe is widely used, but there are also some special-shaped steel pipes such as a square, a rectangle, a semicircle, a hexagon, an equilateral triangle, and an octagonal shape.
For steel pipes subjected to fluid pressure, hydraulic test and radiographic inspection shall be carried out to check the pressure resistance and quality. No leakage, wetting or expansion shall occur under the specified pressure. Some steel pipes shall be carried out according to the standard or the requirements of the purchaser. Crimping test, flaring test, flattening test, etc.
316L Seamless stainless steel pipe is also called 316L stainless steel seamless pipe. It is made of steel ingot or solid pipe blank through perforation and then made by hot rolling, cold rolling or cold drawing. The specifications of the seamless steel pipe are expressed by the outer diameter * wall thickness in millimeters.
316L stainless steel seamless pipe chemical specification:
C≤0.03
Si≤1.0
Mn≤2.00
P≤0.045
S≤0.030
Ni:10.0-14.0
Cr:16.0-18.0
Mo:2.0-3.0
316L stainless steel seamless pipe Application:
316L is a kind of molybdenum-containing stainless steel. Because the steel contains molybdenum, the total performance of the steel is better than that of 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% or higher than 85%, 316L stainless steel has a wide range. use. 316L stainless steel also has good resistance to chloride attack and is therefore commonly used in marine environments.
316L stainless steel has a maximum carbon content of 0.03 and can be used in applications where annealing is not possible and maximum corrosion resistance is required.
316L stainless steel seamless pipe surface:
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.
