Type 304 Sheets
Type 304 Sheets
Type 304 Stainless Steel (UNS S30400, S30403) is the fundamental "18-8" chromium-nickel austenitic stainless steel. It combines excellent mechanical properties with remarkable resistance to many corrosive agents, offering high resistance to rust and excellent fabrication capabilities across a wide range of industries.
- 304 Stainless Steel (UNS S30400)
- 18-8 Chromium-Nickel
- Austenitic stainless
- Excellent corrosion resistance
- Good weldability
- Sheet material
Overview
Type 304 Stainless Steel Sheets represent the industry standard for austenitic stainless steel, offering exceptional versatility and reliability across countless industrial applications. As the fundamental '18-8' chromium-nickel alloy, Type 304 provides an optimal balance of mechanical properties, fabrication characteristics, and resistance to corrosion, making it the most widely used stainless steel in the world.
Type 304 Sheets contain approximately 18% chromium and 8% nickel, which creates a robust passive layer that protects against oxidizing environments. This chemical composition delivers outstanding performance in mild atmospheric conditions, fresh waters, and many chemical corrodents. The austenitic structure ensures good toughness and ductility, even at cryogenic temperatures, while maintaining strength at elevated temperatures up to 870C (1600F).
Type 304 Stainless Steel Sheets serve diverse industries including food processing equipment, kitchen appliances, architectural trim, chemical containers, heat exchangers, and pharmaceutical equipment. Their excellent formability and weldability make them ideal for fabrication into tanks, piping systems, and structural components where corrosion resistance is paramount.
The primary benefits of Type 304 Sheets include high corrosion resistance to a wide range of atmospheric and chemical environments, excellent fabrication characteristics allowing for deep drawing and severe forming operations, good mechanical properties across temperature extremes, and hygienic surfaces that are easy to clean and maintain. These sheets offer exceptional value through long service life with minimal maintenance requirements, reducing total cost of ownership for industrial operations.
