304 Stainless Steel Sheet

304 Stainless Steel Sheet is an austenitic stainless steel sheet primarily composed of 18% chromium (Cr) and 8% nickel (Ni); it is one of the most widely used stainless steel materials available.

It features excellent corrosion resistance, heat resistance, processability, and weldability. Under normal temperatures and in general environments, it is highly resistant to rusting, while simultaneously possessing a favorable balance of strength and toughness.

Key Features:

Excellent Corrosion Resistance: Suitable for use in humid environments and those involving weak acids or bases.

Good Processability: Easily stamped, bent, cut, and welded.

High Hygienic Standards: Features a smooth surface that is easy to clean, meeting the requirements for food-grade applications.

Stable Overall Performance: Demonstrates reliable performance in both industrial and civil applications.

Why is 304 stainless steel a widely used material in both industrial and civilian applications? 

Its core strength lies in its balanced performance, strong applicability, and outstanding overall cost-effectiveness.

1. Excellent Corrosion Resistance:

The standard ratio of 18% chromium and 8% nickel allows for the rapid formation of a dense passivation film on the surface, providing excellent corrosion resistance to air, fresh water, weak acids and alkalis, and most organic solvents, meeting the corrosion protection requirements of typical outdoor, kitchen and bathroom, and fluid transportation applications.

2. Stable Mechanical Properties:

Room temperature tensile strength ≥515MPa, yield strength ≥205MPa, elongation ≥40%, combining strength and toughness, with outstanding impact resistance and deformation resistance, suitable for various forming processes such as stamping, bending, and rolling.

3. Excellent Processability:

Excellent plasticity and weldability, no heat treatment hardening, can be smoothly processed by cold rolling, polishing, wire drawing, laser cutting, etc., suitable for various surface treatments such as 2B, 8K mirror finish, and anti-fingerprint.

4. Balanced Heat and Low Temperature Performance:

Stable use in a temperature range of -196℃ to 800℃, high-temperature oxidation resistance and low-temperature non-embrittlement, meeting the application requirements of both high-temperature equipment and low-temperature working conditions.

Product Advantages

304 Stainless Steel Sheet is one of the most widely utilized austenitic stainless steels; due to its balanced combination of properties, it occupies a central position in both industrial and everyday manufacturing. Its primary advantages are as follows:

1. Excellent Corrosion Resistance

Containing approximately 18% chromium and 8% nickel, 304 stainless steel forms a dense oxide film on its surface. This effectively resists corrosion from water, air, weak acids, and weak bases, making it particularly suitable for use in humid or mildly corrosive environments.

2. Good Processability

It exhibits excellent cold and hot working properties, allowing for various processing methods such as cutting, bending, stamping, and welding. It is resistant to cracking, making it ideal for the fabrication of complex structural components.

3. Superior Weldability

304 stainless steel sheet demonstrates high stability during the welding process and is resistant to intergranular corrosion. It retains excellent strength after welding and is widely used in welded structural assemblies.

4. High Strength and Good Toughness

It maintains excellent mechanical properties under both ambient and low-temperature conditions. Possessing a balance of strength and toughness, it is resistant to brittle fracture, making it suitable for load-bearing structural applications.

5. Aesthetic Appeal and Ease of Maintenance

It features a high surface finish that can be further enhanced through treatments such as polishing or brushing. Its attractive appearance and ease of cleaning make it suitable for decorative and food-grade applications.

6. Wide Range of Applications

It is extensively used in fields such as food processing equipment, kitchenware, medical instruments, architectural decoration, chemical equipment, and industrial structural components, establishing it as a quintessential "general-purpose stainless steel material."
