Polished Stainless Steel Strips 309S Material with Sufficient Inventory

Stainless steel coil is one of the important stainless steel plates. According to different production processes, it can be divided into cold-rolled stainless steel coils and hot-rolled stainless steel coils. According to different materials, they can be divided into two categories. Stainless steel coils made of steel, ferrite, martensite and duplex. Like other types of stainless steel plates, stainless steel coils have strong corrosion resistance and rust resistance, and their excellent quality makes them important industrial raw materials and building materials. With the continuous development of the national economy, the application fields of stainless steel coils have become more and more extensive, and the market prospects are very promising by the industry.

3. Surface:

No.4	It has good 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	It is 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.
8K	It is in a mirror state. Processing technology: 2D or 2B products are ground and polished to a mirror effect with a suitable abrasive material.
2B	It is silvery 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.
1D	surface has discontinuous particles, also known as matte. Processing technology: hot rolling + annealing shot peening pickling +cold rolling + annealing pickling.
2D	It is slightly shiny silvery 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).
SB	The surface is smooth, the texture is clear, the texture is delicate, the appearance is comfortable, and the taste is high-grade.It is widely praised by consumers especially in kitchen appliances.
