Stainless Steel Seamless Pipe Surface
Jaway Steel is a known manufacturer and exporter of stainless steel seamless pipe and tube, which has some great features to offer such as high tensile strength, withstand high temperatures and pressure, rugged construction, etc.
stainless steel seamless pipe surface:
Surface grade
Stainless steel has the following states, the state is different, 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 technology
1D—The surface has discontinuous particles, which is also called matte. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B—Silver white and has better gloss and flatness than 2D surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.
2D—Slightly shiny silver-white. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
No.3—has better gloss and rough surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 100 ~ 120 abrasive materials (JIS R6002).
No.4—has better gloss and fine lines on the surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 150 ~ 180 abrasive material (JIS R6002).
HL—Silver gray with hair streaks. Processing technology: Polish the 2D product or 2B product with a suitable size of abrasive to make the surface appear continuous grain.
BA—The surface gloss is excellent and has a high reflectivity, just like the mirror surface. Processing technology: hot rolling + annealing peening pickling + cold rolling + annealing pickling + surface polishing + quenched and tempered rolling.
MIRRO—mirror surface. Processing technology: 2D or 2B products are ground and polished to a mirror effect with a suitable size of abrasive material.
