304
About the Materials

The Anatomy of 304 Stainless.

304 stainless steel is a versatile austenitic alloy containing approximately 18% chromium and 8% nickel. It possesses excellent corrosion resistance, mechanical properties, and processability. Characterized by high-temperature resistance and ease of cleaning, it is widely used across architectural, medical, and culinary applications.

Section 01

Key Characteristics

Engineered for versatility, hygiene, and structural reliability.

Corrosion Shield

A dense protective layer of chromium oxide formed on the surface allows it to perform exceptionally well in air, water, and most organic/inorganic acids.

Thermal Endurance

It has strong heat resistance and can be used continuously in various environments, typically performing well at temperatures up to 800–900°C.

Processability

It features excellent plasticity and weldability, making it highly adaptable and easy to perform various cold and hot working processes.

Physical Magnetism

304 is almost non-magnetic in the annealed state. However, it may develop weak magnetic properties after rigorous cold working (such as stamping or bending).

Section 02

Chemical
Composition

The core of 304 consists of the renowned 18/8 ratio. The dominant addition of Chromium provides its signature oxidation resistance and surface self-healing properties.

CHROMIUM (Cr) ≥ 18.0%

Forms a dense, self-healing oxide protective layer

NICKEL (Ni) ≥ 8.0%

Enhances ductility, toughness, and stability

CARBON (C) ≤ 0.08%

Strictly controlled to prevent carbide precipitation
