Key Features & Properties of SS 304 / 304L

• Excellent corrosion resistance to atmospheric conditions, water, food acids, organic chemicals, dyestuffs, and a wide range of industrial chemicals
• Outstanding resistance to most oxidizing acids including nitric acid and acetic acid
• Non-magnetic in the annealed condition
• Not hardenable by heat treatment; strength increased by cold working
• Excellent formability — outstanding drawing, forming, and deep drawing properties
• Easy to fabricate, roll form, spin, and stamp
• Superior weldability, especially SS 304L (low carbon — minimizes carbide precipitation)
• Good cryogenic toughness at low temperatures
• Good high-temperature oxidation resistance up to approximately 870°C in intermittent service
• Good cleanability and hygienic properties, ideal for food and pharmaceutical industries
• Excellent surface finish and aesthetic appeal
• Long service life and dimensional accuracy
• Cost-effective compared to higher alloyed grades such as SS 316 / 316L
