There are two most popular stainless steel type called has aisi 304 & 316. Let see differences between aisi 304 & aisi 316 and there uses in different industries, application, composition and material.

AISI 304 Stainless Steel

AISI 304 metal is known for resistant to rust, corrosion resistance in different application has per industries needs. AISI 304 is mainly used in Aerospace,Construction and more.

• Percentage of Component
• 18 to 20% chromium
• 8 to 10.5% nickel
• Carbon less than 0.08%
• Only 2% manganese
• Silicon less than 1%
• About 0.045% phosphorus
• No sulphur ≤0.03%

AISI 316 stainless steel

It’s even tougher and can resist rust even better. Its an upgrade version of 304 stainless steel.

• Percentage of Component
• 16 to 18% chromium
• Nickel 10 to 14 percent
• Molybdenum 2% to 3%
• Carbon less than 0.08%
• Only 2% manganese
• Silicon less than 1%
• About 0.045% phosphorus
• No Sulphur ≤0.03%

Here’s a comparison table highlighting the differences between AISI 304 and AISI 316 stainless steel in various applications

Stainless steels stand out due to their exceptional resistance to rust. Their combination of strength and minimal care requirements make them ideal for various applications. They are prevalent in building materials, construction, medical devices, and food equipment. In certain situations, preventing rust is crucial for a structure’s long-term integrity. Rust can deteriorate metal, weakening its ability to support loads over time. Temperature fluctuations significantly influence corrosion, speeding up the process and creating demanding conditions. Stainless steels excel in such environments. They outperform coated structural steels since coatings tend to be more susceptible to damage under these conditions.
