High-Quality Stainless Steel Round Metal Bars (2mm, 3mm, 6mm) from China Suppliers and Factory - 201, 304, 316 Grades
Stainless Steel Rod
Stainless steel bars are long, round-sectioned stainless steel profiles, with mainstream grades including 201, 304, and 316L—316L stands out for its exceptional corrosion resistance in harsh environments. Their key advantages lie in strong corrosion resistance, high tensile strength, and good toughness, enduring moisture, pressure, and temperature variations. They’re easy to machine, weld, or polish, with surface finishes like pickling, 2B, and mirror polishing blending functionality and aesthetics, boasting a longer service life than carbon steel bars.
Applications: Machinery manufacturing (shafts, gears, fasteners); construction (embedded parts, structural supports); automotive sectors (suspension parts); medical fields (surgical instrument components); hardware production (handles and hinges).
Installation & Use: Requires degreasing and derusting. Connection methods include welding, threaded machining, or precision fitting. Avoid direct contact with carbon steel to prevent galvanic corrosion. For acidic/alkaline media, select 316L grade.
Maintenance: Clean daily with neutral detergent. Remove minor rust with specialized removers then re-passivate. Inspect for cracks or deformation quarterly and store in dry, ventilated areas.
