304 stainless steel is a widely used austenitic stainless steel alloy known for its corrosion resistance, strength, and versatility. Austenitic stainless is the most widely used category of stainless steel due to its high corrosion resistance, excellent formability, and good mechanical properties. 304 SS is part of the 300 series of stainless steels and is commonly used in a variety of industries due to its durability and ease of fabrication.

Composition:

18-20% Chromium (Cr) – Provides corrosion and oxidation resistance
8-10.5% Nickel (Ni) – Enhances strength and resistance to acids
Iron (Fe) as the base metal
Small amounts of Carbon (C), Manganese (Mn), Silicon (Si), and Phosphorus (P)

Key Properties:
✔ Excellent Corrosion Resistance – Resists rust and oxidation in most environments, including moisture and mild chemicals.✔ Good Weldability – Easily welded without post-weld heat treatment.✔ High Strength & Durability – Tough and maintains strength in high temperatures.✔ Non-Magnetic (in annealed form) – Can become slightly magnetic after cold working.✔ Hygienic & Easy to Clean – Common in food and medical industries.

Common Applications:

Pipe fittings & flanges (chemical, food, water industries)
Kitchen equipment (sinks, cookware, appliances)
Medical instruments (surgical tools, implants)
Architectural & automotive parts
