304 stainless steel plate is a type of austenitic stainless steel known for its excellent corrosion resistance, high strength, and good formability. It is one of the most commonly used stainless steel alloys and is classified under the American Iron and Steel Institute (AISI) designation of 304. They are a relatively low cost stainless (compared to 316/316L stainless). Referred standards ASTM A-240, ASME SA -240.

Key Features:

• Composition: Typically contains approximately 18% chromium and 8% nickel, which contribute to its corrosion resistance and overall durability.
• Corrosion Resistance: Resistant to a wide range of chemicals and environments, making it suitable for various applications.
• Mechanical Properties: Offers good tensile strength and workability, allowing it to be easily formed and shaped for different uses.
• Standards: It adheres to several standards, including ASTM A-240 and ASME SA-240, which specify requirements for plates, sheets, and strips of stainless steel.

• Good corrosion resistance than other steel in variety of different media
• Excellent low temperature performances
• Good welding characteristics
• Post weld annealing is not normally required
• Heat resistant performances
• Hot workability such as punching or bending
• No heat treatment hardening phenomenon (non-magnetic, use temperature -196 ℃ ~ 800 ℃)

Applications:

• Energy and Heavy Indsutries - Oil and Gas, Electrical steel (Silicon Steel), Solar Board.
• Power Plant.
• Heat Exchangers, Boilers
• Chemical Storage Vessels
• Automotive and Transportation
• Architectural and Construction
• Marine Building
• Medical Equipment
• Food Machine Manufacturing, Food and Catering

304 Stainless Steel Sheet Plate Properties:

Chemical Composition 304 vs 316 stainless steel

Mechanical Properties 304 vs 316 stainless steel

These values are applicable for thicknesses of 1.5 inches (38 mm) or less. For thicknesses greater than 38 mm, the tensile strength and yield strength of 304 stainless steel are equivalent to those of 316 stainless steel, while 304L matches 316L. However, the hardness levels differ between the two materials.

Difference between 304/304L and 316/316L Stainless Steel Plates

Both grades are austenitic stainless steels, recognized for being among the most widely used and versatile types of steel. While 304/304L stainless steel plates and sheets offer excellent corrosion resistance, 316/316L plates contain a higher nickel content, which enhances their corrosion resistance further, particularly in marine applications.
