304 stainless steel is one of the most widely used and versatile stainless steel grades, belonging to the austenitic stainless steel family (300 series). It is often referred to as "18/8 stainless steel" due to its composition of approximately 18% chromium (Cr) and 8% nickel (Ni). This composition gives it excellent corrosion resistance, formability, durability, and aesthetic appeal, making it suitable for a broad range of applications.
Key Properties of 304 Stainless Steel
Corrosion Resistance
304 stainless steel exhibits excellent resistance to rust, oxidation, and corrosion in various environments, including mild acids, alkalis, and atmospheric conditions.
Good Mechanical Strength
It has high tensile strength, toughness, and good fatigue resistance, even at elevated temperatures.
Weldability
It can be easily welded using conventional welding methods, maintaining its mechanical properties after welding.
Formability and Ductility
304 stainless steel is easy to fabricate, bend, and shape due to its excellent ductility and workability.
Hygiene and Cleanability
Its smooth, non-porous surface makes it easy to clean and maintain, making it ideal for food, medical, and hygiene-related applications.

(Length: coil type or it can be produced as customer requirements)
Inner and outer diameter
Inner Diameter: 300、400、500（Customized according to the customer's machine size）
Outer diameter: The outer diameter range is determined based on the width of the material required by the customer and the maximum weight of a single trailer.
(The weight of a single trailer generally does not exceed 2 tons to ensure that the goods will not be damaged during transportation and moving.)
Surface
DSM offers a variety of different surface treatments for stainless steel plates. There are1U, 1C, 1D, 1E, 2B, BA, No.4, TR, HL etc.
Label
The label on each pallet shows the relevant material information, including coil number, steel type, size, net weight, etc.; it is convenient for customers to count the goods.
