Top 316 Stainless Steel Rectangular Tube Manufacturers in China
316 Stainless Steel Rectangular Tubes In the chemical processing industry, marine applications, and even structural projects, this tubing is used. This is due to its exceptional corrosion resistance and tensile strength, which makes it perfect for ruthless conditions and harsh structural demands.
316 Stainless Steel Rectangular Tube Specification
316 Stainless Steel Rectangular Tubing provides exceptional durability and corrosion resistance, crafted from high-quality stainless steel to meet stringent performance demands.
| Category | Details |
|---|---|
| Characteristics | Austenitic stainless steel with molybdenum (2-3%), offering enhanced corrosion resistance, high strength, and excellent formability. Low carbon (316L) variant available for improved weldability. |
| Surface Treatment | Typically available in mill finish, polished (e.g., 180/240/320 grit), or brushed finishes. Optional electropolishing for enhanced smoothness and corrosion resistance. |
| Dimensions and Specifications | Outer dimensions: 1/2" x 1" to 4" x 6" (common sizes); Wall thickness: 0.02" to 0.25" (0.5mm to 6mm); Length: Up to 20 ft (6m) or custom cut. Seamless or welded options available. |
| Corrosion Resistance | Superior resistance to pitting and crevice corrosion in chloride environments (e.g., marine, chemical). Resists acids like sulfuric, acetic, and phosphoric. Not immune to warm seawater pitting. |
| Mechanical Properties | Yield Strength: ~205 MPa (30 ksi); Tensile Strength: ~515 MPa (75 ksi); Elongation: ~40%; Hardness: ~95 HRB (Rockwell B). Values vary slightly with cold working or heat treatment. |
| Processability | Good weldability (TIG/MIG recommended; 316L preferred for welds); easily formed (bending, drawing); machinable with proper tools. Annealing at 1038¡ãC (1900¡ãF) enhances corrosion resistance post-processing. |
| Applications | Food processing (e.g., tubing for sanitary systems), pharmaceutical equipment, marine structures, chemical processing, architectural components, heat exchangers, and industrial frameworks. |
| Standards | ASTM A554 (ornamental tubing), ASTM A269/A249 (sanitary tubing), ASME SA213 (heat exchanger tubing), UNS S31600/S31603 (316/316L), EN 1.4401/1.4404. |
