Product Description

304 Stainless Steel Square Tube & Rectangular Tube English Introduction

1. Product Overview

304 stainless steel square tube and rectangular tube, also called stainless steel hollow section, are welded hollow profiles made from 304 austenitic stainless steel strip (UNS S30400). Manufactured by roll forming and longitudinal welding, normally followed by weld seam grinding and surface finishing. It complies with ASTM A554, EN 10219, GB/T 12771 standards. This 18-8 stainless grade has bright surface options: 2B, BA, hairline, mirror finish. Our products have smooth weld seam, straight dimension, stable wall thickness, and can be supplied with MTR 3.1 material test certificate.

2. Chemical Composition (wt%, ASTM A554)

Carbon (C): ≤0.08
Silicon (Si): ≤1.00
Manganese (Mn): ≤2.00
Phosphorus (P): ≤0.045
Sulfur (S): ≤0.030
Chromium (Cr): 18.00 ~ 20.00
Nickel (Ni): 8.00 ~ 10.50
Iron (Fe): Balance

3. Mechanical Properties (Annealed Condition, Room Temperature)

Ultimate Tensile Strength: ≥515 MPa
0.2% Yield Strength: ≥205 MPa
Elongation: ≥35%
Hardness: ≤201 HB / ≤92 HRB
Density: 7.93 g/cm³

Note: Good ductility, easy for cutting, bending, drilling and welding.

4. Core Advantages

Excellent corrosion resistance: Resists atmospheric rust, fresh water, weak acid and alkali, suitable for outdoor and humid environments.
Uniform dimension & smooth weld line: Good straightness, consistent wall thickness for assembly.
Great processability: Easy to cut, bend, punch and weld without complicated heat treatment.
Multiple surface options: 2B, BA, hairline, mirror finishes available for decorative and structural needs.
Long service life & low maintenance: No painting required, low maintenance cost.

5. Applications

Architectural Decoration: Stair handrails, balcony railings, elevator frames, door & window frames, decorative structures
Structural Engineering: Support frames, guard barriers, equipment stands, outdoor structural frames
Food & Sanitary Industry: Food equipment racks, sanitary support frames
Mechanical Equipment: Machine frames, protective covers, conveyor brackets
