A2 stainless steel (Grade 304) consists primarily of iron (Fe), chromium (Cr), and nickel (Ni), with a chromium content of approximately 18% and a nickel content of approximately 8%. It also contains small amounts of carbon (C), manganese (Mn), silicon (Si), and other elements. This composition provides the following properties:
Excellent oxidation and corrosion resistance, enabling it to withstand corrosion from media such as the atmosphere, water, acids, and alkalis.
Good workability, making it easy to cut, weld, bend, and form.
Excellent mechanical properties, including good strength and toughness, as well as good ductility at low temperatures.
An attractive appearance, with a smooth, lustrous surface when polished.

Hot-rolled stainless steel sheets are rolled at temperatures above the recrystallization temperature (approximately 1000°C or higher), and therefore:
They are available in a wide range of thicknesses, typically from 3 mm to over 100 mm, making them suitable for large structural components.
The surface features a No. 1 industrial finish—matte and slightly rough—making it suitable for industrial applications.
Low internal stress reduces deformation during subsequent processing.
Lower cost, making it suitable for bulk purchases.
Thickness: 3 mm–100 mm or more; medium-thick plates typically range from 3 to 16 mm, while thick plates can be 18 mm or more.
Width: 1,000 mm, 1,219 mm, 1,500 mm, 2,000 mm, etc.; can be cut to size as needed.
Length: Typically 6,000 mm or cut to length as needed.
Due to its well-balanced properties, A2 hot-rolled stainless steel sheet is widely used in the following areas:
Roofing, exterior wall panels, railings, doors, and windows, etc.
Processing equipment, tableware, storage tanks, etc.
Reactors, piping, liquid storage tanks, etc.
Kitchen appliances, bathroom fixtures, furniture hardware, etc.
Automotive parts, medical devices, precision instruments, etc.
1. What is A2 stainless steel sheet?
A2 stainless steel is equivalent to AISI 304 stainless steel under the ISO 3506 classification. It offers excellent corrosion resistance, good weldability, and is widely used in construction, food processing, and industrial fabrication.
2. Is 304 stainless steel sheet suitable for outdoor applications?
Yes. 304 stainless steel provides excellent resistance to atmospheric corrosion and moisture, making it suitable for many outdoor environments. For highly corrosive marine or chloride-rich conditions, 316 stainless steel is generally recommended.
3. What does No.1 Finish mean?
No.1 Finish is a hot rolled, annealed, and pickled surface finish. It has a matte appearance and is commonly used for pressure vessels, industrial equipment, chemical processing, and structural applications.
4. Can you provide custom cutting services?
Yes. We offer cut-to-size services, including laser cutting, plasma cutting, water jet cutting, CNC machining, and custom dimensions according to customer drawings.
5. What is the standard size of this sheet?
The standard size is 3 mm × 1220 mm × 2440 mm (4 ft × 8 ft). Other thicknesses, widths, and lengths are available upon request.
6. Which international standards do your products comply with?
Our 304 stainless steel sheets are manufactured according to ASTM A240, ASTM A480, EN 10088, and JIS G4304, ensuring consistent quality and global compatibility.
