ASTM A240 2205 S31803 S32205 NO.1 Surface Duplex Steel Plate 8.0*1500*6000mm For Sea

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 chemically corrosive media such as acid, alkali and salt. Stainless steel plate has a history of more than a century since it came out in the early 20th century.

Stainless steel features: 1. Complete product specifications and diverse materials;
2. High dimensional accuracy, up to ±0.1mm;
3. Excellent surface quality and good brightness;
4. Strong corrosion resistance, tensile strength and fatigue resistance High strength;
5. Stable chemical composition, pure steel, low inclusion content;
6. Good packaging, preferential price;
7. Non-standard custom.

Chemical Composition

Surface Difference

No.1 (hot rolled): After hot rolling, annealing, pickling and dephosphorization. The surface of the treated steel plate is a dull surface, a bit rough.
Usage: chemical industry equipments.
No.2D: The surface is processed better than No.1, and it is also a dull surface. After cold rolling, annealing, dephosphorization, and finally rolling with a matt roll.
Usage: petrochemical production equipment, auto parts, building materials, pipeline materials, etc.
No.2B: This is the most commonly used in construction applications. Except for the last light cold rolling with a polishing roll after annealing and dephosphorization, the other processes are the same as 2D, the surface is slightly shiny, and it can be polished.
Usage: After adopting the surface treatment method to improve the mechanical properties, it can meet almost all purposes.
BA: After cold rolling, it is processed by bright annealing heat treatment process and modulated and rolled.
Usage: mostly used for home appliances, small mirrors, kitchen equipment and building materials that require high reflectivity.
No.4: First polish with coarse abrasive, and finally grind with 180 grit abrasive.
Usage: Mainly used for bathtubs, building interior and exterior decoration materials, food equipment, etc.
HL (hairline): Use grinding paper of appropriate granularity to make No.4 continuous grinding pattern
Usage: mostly used for building interior and exterior decoration materials and building sash, door, panel, etc.
8K: Continuously polish the stainless steel with a fine abrasive, and then polish it with a very fine polishing paste.
Usage: mirror surface processing, used for decoration materials, mirrors, etc.
