What is 304 Stainless Steel?
Type 304 stainless steel, also known as UNS S30400, is an austenitic stainless steel. It is the most common stainless steel alloy grade, accounting for over 50% of global stainless steel use. It is sold in a variety of product forms, including strip, stripped coils, and blanks, as well as fine, flat, round, and shaped wire. Its versatility and robust performance make it a popular choice for numerous applications across a wide range of industries.
Will 304 stainless steel rust?
It's important to note that while 304 stainless steel will corrode, it won't rust under normal atmospheric conditions. Corrosion of stainless steel only occurs in more corrosive environments or when the steel contains impurities.
What are some common applications for 304 stainless steel?
This stainless steel alloy is widely used in various industries, including medical, automotive, aerospace, food, and industrial, due to its durability, versatility, corrosion resistance, and good mechanical properties.
Common applications include:
Medical implants
Automotive interiors
Automotive safety systems
Flexible metal hoses
Oil and gas well screens
Stamping and deep drawing

Chemical Composition and Properties of 304 Stainless Steel
304 stainless steel contains 18% chromium, 8% nickel, and small amounts of manganese and carbon, and is known for its excellent rust and corrosion resistance. The chromium forms a passive oxide layer on the surface, protecting it from corrosion in a variety of environments, including freshwater, saltwater, and mildly corrosive chemicals.
Due to its excellent corrosion resistance and low reactivity, 304 stainless steel is commonly used in the food, pharmaceutical, and medical industries, where cleanliness and sanitation are crucial.
With its good combination of yield strength, tensile strength, and ductility, 304 stainless steel is a popular choice for a variety of structural and manufacturing applications. It has good tensile properties and can be formed into a variety of shapes without annealing.
It has strong high-temperature resistance, withstanding temperatures up to 700°C for short periods, and good oxidation resistance, withstanding temperatures up to 700°C for extended periods. However, prolonged exposure to air can compromise the metal's overall corrosion resistance, making it more susceptible to corrosion damage from exposure to moisture.
Like other stainless steels, 304 stainless steel is 100% recyclable and can be reused in a variety of applications, making it an environmentally friendly material choice.
