Stainless Steel Grades Explained: From 304 to 904L
Stainless steel is synonymous with durability and cleanliness. Its wide range of grades allows engineers to select the best type for applications ranging from kitchen sinks to oil rigs.
Key Grades and Properties
304: General-purpose; good weldability and corrosion resistance.
316: Added molybdenum enhances chloride resistance; used in marine and chemical settings.
410: High hardness; ideal for cutlery and pumps.
904L: High-performance austenitic stainless steel; resists strong acids.
Advantages
Corrosion Resistance: Chromium content forms a self-healing oxide layer.
Strength: High tensile and yield strength.
Cleanliness: Non-porous and easy to sanitize.
Temperature Tolerance: Performs well in both cryogenic and high-temperature environments.
Applications
Food Processing: Tanks, tables, and piping.
Medical Equipment: Surgical tools, implants.
Construction: Handrails, facades, fasteners.
Chemical Plants: Tanks, pipes, heat exchangers.
Choosing the right stainless steel grade can significantly extend the life and performance of a product.
