What is ASTM and AISI?
ASTM stands for the American Society for Testing and Materials. The AISI stands for the American Iron and
Steel Institute.
What type of material is SUS?
Stainless steel is the alloy of chromium and nickel. Sometimes, it is referred as SUS, an acronym from Japanese
Industrial Standards (JIS). Stainless steel has various types to meet various needs, and is used in numerous
precision machine parts, bolts, and nuts.
What is No 1 finish in stainless steel?
Image result for surface of stainless steel
No. 1 Finish is produced by rolling stainless steel that has been heated prior to rolling (hot-rolling). This is followed
by a heat treatment that produces a uniform microstructure (annealing) and ensures that the stainless steel will
meet mechanical property requirements.

Overall Summary
This product listing covers a versatile range of Austenitic Stainless Steel Sheets in thicknesses from very thin foil to medium plate. It includes both standard and specialty grades, available in different processing routes (hot or cold rolled) and with various surface finishes, from industrial to decorative.
1. Breakdown by Stainless Steel Grade (ASTM/AISI/SUS)
These are all Austenitic (non-magnetic, nickel-chromium) stainless steels, but with different compositions for specific properties.
Standard Austenitic Grades
-
AISI 201 & 202: Low-nickel, high-manganese grades. Cost-effective alternatives to 304, but with generally lower corrosion resistance. Common in interior applications, appliances, and less corrosive environments.
-
AISI 304L: The low-carbon version of 304. Excellent all-around corrosion resistance and weldability. The “L” reduces susceptibility to corrosion in welded areas. The most versatile and widely used grade.
-
AISI 316L: The low-carbon version of 316. “Marine Grade” stainless. Adds Molybdenum for superior resistance to chlorides and acids. Essential for coastal, chemical, and marine applications.
-
AISI 321: Stabilized with Titanium. Excellent for high-temperature service (up to ~900°C) and for components that will be welded and cannot be annealed afterward. Used in heat exchangers and aircraft exhausts.
High-Temperature & Specialty Austenitic Grades
-
AISI 309S & 310S: High-temperature resistant grades.
-
309S: Good resistance to oxidation up to 980°C. Often used as heat baffles or for furnace parts.
-
310S: Higher chromium and nickel content for even better oxidation resistance (up to 1100°C). Used for high-temperature furnaces, kilns, and radiant tubes.
-
2. Breakdown by Surface Finish (2b, No. 4, BA)
The surface finish is a critical part of this listing, defining the sheet’s appearance and application.
-
2B: A cold-rolled, dull finish. This is the most common standard finish for stainless steel sheets. It has a smooth, matte grey appearance. It is suitable for both industrial and decorative applications and is often the starting point for further polishing.
-
No. 4 (Brushed): A polished linear finish. Created by mechanically polishing the sheet with abrasives, resulting in a consistent, satiny look with visible parallel lines. Extremely popular for architectural cladding, elevator interiors, appliances, and restaurant equipment.
-
BA (Bright Annealed): A smooth, highly reflective, mirror-like finish. Achieved by annealing the steel in a controlled atmosphere furnace to prevent surface oxidation. It has a brighter, more uniform appearance than a mechanically polished “Mirror” (No. 8) finish. Used for high-end decorative trim, reflectors, and modern architectural elements.
3. Breakdown by Processing & Thickness
-
Hot Rolled / Cold Rolled: This refers to how the steel is processed to its final thickness.
-
Hot Rolled (HR): Processed at high temperatures. Has a rough, scaled surface and is generally less precise. More economical for thicker plates.
-
Cold Rolled (CR): Processed from HR coil at room temperature. Results in a smoother surface, tighter dimensional tolerances, and increased strength. The 2B, No. 4, and BA finishes are all applied to Cold Rolled sheets.
-
-
Thickness: 0.1mm – 3.0mm: This range covers:
-
0.1mm – 0.5mm: Very thin foil/sheet for specialized applications, gaskets, or delicate decorative work.
-
0.5mm – 1.5mm: Standard sheet range for appliance panels, kitchen backsplashes, signage, and architectural cladding.
-
1.5mm – 3.0mm: Heavier sheet for countertops, industrial equipment covers, and structural decorative elements.
-
