ASTM 304L 304 310S Stainless Steel Coils Hot or cold Rolled 8K BA surface

Stainless steel coil

Stainless steel coils are divided into austenite, ferrite, martensite, dual-phase (ferrite-austenite) stainless steel cold rolled coils and stainless steel hot rolled coils.

Stainless steel plate: divided into cold-rolled plate and hot-rolled plate, its surface has bright surface, matte surface, matt surface. Commonly known as stainless steel plate, there are 2B plate, BA plate.
In addition, other light colors can be plated according to customer requirements.
The specifications of the plates mainly include: 1m*1m 1m*2m 1.22m*2.44m 1.5m*3m 1.5m*6m,
If the customer's demand is large, we can cut it according to the customer's size. In addition, we can make brushed plates, anti-skid plates, and electroplated plates.

N0.1
After hot rolling, it undergoes heat treatment and pickling treatment.
2B
After cold rolling, heat treatment, pickling or similar treatment is carried out, and finally it is smoothed to obtain the appropriate gloss.
2D
After cold rolling, heat treatment, pickling or similar treatment or matte surface is carried out.
3#
100~200# grinding belt grinding products.
4#
150~180# grinding belt grinding products.
HL
Abrasive material with appropriate particle size is polished to make the surface continuous grinding grain.

In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness of various stainless steel coils meet the requirements, stainless steel coils must be subjected to heat treatment such as annealing, solution treatment, and aging treatment before delivery. The corrosion resistance of the stainless steel coil mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure of the stainless steel coil, and the main role is the chromium element. Chromium has high chemical stability and can form a passivation film on the steel surface to isolate the metal from the outside world, protect the steel plate from being oxidized, and increase the corrosion resistance of the steel plate. After the passivation film is destroyed, the corrosion resistance decreases.

Stainless steel coils are widely used in chemical, food, medicine, paper, petroleum, atomic energy and other industries, as well as various parts and components of construction, kitchen utensils, tableware, vehicles, and household appliances
