304 stainless steel is a widely used and versatile austenitic stainless steel alloy. It is part of the 300 series stainless steel family, which contains chromium and nickel as its main alloying elements.
Here are some key properties and characteristics of 304 stainless steel:
Corrosion Resistance: 304 stainless steel exhibits excellent resistance to corrosion in a wide range of environments. It is particularly resistant to oxidizing acids, such as nitric acid, and can withstand moderately aggressive organic acids.
Strength and Durability: 304 stainless steel has good mechanical properties, including high tensile strength, which makes it suitable for various structural applications. It has a relatively high yield strength and excellent toughness.
Heat Resistance: 304 stainless steel offers good heat resistance and can withstand high temperatures without significant scaling or deformation. It retains its strength and mechanical properties at elevated temperatures, making it suitable for high-temperature applications.
Formability and Weldability: 304 stainless steel is highly formable, allowing it to be easily fabricated into various shapes. It can be rolled, bent, and stamped without losing its properties. Additionally, it exhibits good weldability, making it suitable for welding and joining processes.
Hygienic and Food-Grade Applications: Due to its excellent corrosion resistance and ease of cleaning, 304 stainless steel is commonly used in the food processing industry, pharmaceutical industry, and other applications where hygiene is crucial.
Wide Range of Applications: 304 stainless steel is utilized in a wide range of industries and applications, including but not limited to: automotive, aerospace, construction, chemical processing, oil and gas, food processing equipment, kitchen appliances, and medical devices.

Possible alternative grades to 304 grade stainless steel
| Grade | Why it might be chosen instead of 304 |
| 301L | A higher work hardening rate grade is required for certain roll formed or stretch formed components. |
| 302HQ | Lower work hardening rate is needed for cold forging of screws, bolts and rivets. |
| 303 | Higher machinability needed, and the lower corrosion resistance, formability and weldability are acceptable. |
| 316 | Higher resistance to pitting and crevice corrosion is required, in chloride environments |
| 321 | Better resistance to temperatures of around 600-900°C is needed…321 has higher hot strength. |
| 3CR12 | A lower cost is required, and the reduced corrosion resistance and resulting discolouration are acceptable. |
| 430 | A lower cost is required, and the reduced corrosion resistance and fabrication characteristics are acceptable. |
