Key Properties
-
Corrosion Resistance: 304/304L stainless steel square bar performs exceptionally well in atmospheric conditions, acidic industrial environments, and chloride-exposed settings such as coastal areas.
-
Strength: This grade of stainless steel offers high tensile and yield strength, making it suitable for heavy structural loads and long-term durability in construction.
-
Workability: Whether you're cutting, welding, bending, or machining, these square bars handle easily and maintain shape integrity.
-
Dual Certification (304/304L): Lower carbon content in 304L improves weldability and reduces the risk of carbide precipitation, especially important in welded structures.
Manufacturing Process
Our 304 stainless steel square bar factory utilizes state-of-the-art manufacturing lines that include both hot and cold forming processes. Precision is key in delivering exact square dimensions and consistent surface finish. Here’s how it works:
-
Forming: Either cold-rolled or hot-pressed, depending on the desired strength and finish quality.
-
Heat Treatment: Annealing enhances ductility and removes internal stress.
-
Surface Processing: Polishing, brushing, or mirror finishing available based on aesthetic or functional requirements.
In-house quality control includes ultrasonic testing, surface inspection, dimensional verification, and chemical composition analysis, ensuring that each 304/304L stainless steel square bar meets international and customer-specific standards.
Applications
Because of its excellent formability and corrosion resistance, 304/304L stainless steel square bar is widely used in the following industries:
-
Construction: Used for railings, supports, and structural elements in commercial and residential buildings.
-
Machinery: Essential for producing frames, brackets, and load-bearing machine parts.
-
Automotive: Fabrication of trim, supports, and safety-reinforcing elements.
-
Furniture: Brushed and mirror-finished versions used in frames and visible structural parts.
-
Food Industry: Suitable for kitchen equipment, counters, and machinery frames due to food-grade compliance.
-
Marine & Coastal Use: Its corrosion resistance allows use near saltwater environments, though more aggressive environments may benefit from 316 grades.
