AISI Stainless Steel Flat Sheet Plate SS410 SS409 SS420 2B

The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-free. Stainless steel plate refers to steel plate resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to steel plate resistant to corrosion by chemical corrosive media such as acid, alkali, salt, etc.

Stainless Steel Surface Treatments

1D—The surface has discontinuous particles, which is also called matte. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.

2D—Slightly shiny silver-white. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.

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

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

No.3—has better gloss and rough surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 100 ~ 120 abrasive materials.

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 materials.

HL—Silver gray with hair streaks. Processing technology: Polish the 2D product or 2B product with a suitable size of abrasive material to make the surface appear continuous grain.

MIRROR Machining —is in a mirror state. Processing technology: 2D or 2B products are ground and polished to a mirror effect with a suitable abrasive material.
