Premium Stainless Steel Pipe Tube | Hot-Rolled 304 & 904L Deals
Product Overview
Our stainless steel pipe tube solutions are engineered for industrial excellence, combining corrosion resistance, high-temperature durability, and cost-effectiveness. Designed for applications in oil/gas, construction, marine, and chemical industries, these pipes comply with ASTM, ASME, and ISO standards. The stainless steel 304L pipes & tubes variant offers enhanced weldability and low-carbon properties, while the 904L grade excels in extreme environments.
Technical Specifications
Key Attributes & Dimensions

Performance Characteristics
1. Tensile & Bend Strength
- Tensile Strength:
- 304L: 485–620 MPa | 904L: 490–690 MPa.
- Superior resistance to stress corrosion cracking, ideal for high-pressure pipelines.
- Bend Strength:
- 304L maintains ductility even at subzero temperatures (-196°C), while 904L withstands sulfuric acid environments.
2. Weight Calculation
Use the formula:
Weight (kg/m) = (OD – Thickness) × Thickness × 0.02491
Example: For a 50mm OD pipe with 2mm thickness:
(50 – 2) × 2 × 0.02491 = 2.35 kg/m
3. Rust Prevention
While stainless steel pipe tube is corrosion-resistant, improper handling or exposure to chlorides (e.g., seawater) can cause localized pitting. Regular passivation and avoiding contact with carbon steel tools mitigate this.
4. Identification & Marking
- Laser-etched labels include: Material Grade (e.g., 304L), Standard (ASTM/ASME), OD/Thickness, and Heat Number.
- Color-coded caps distinguish grades: Blue for 304L, Yellow for 904L.
Manufacturing Process
| Stage | Description |
|---|---|
| Hot Rolling | Heated billets shaped into pipes at 1100–1250°C for uniform grain structure. |
| Cold Drawing | Precision sizing for tight tolerance (±0.1mm). |
| Welding (Welded Tubes) | TIG or laser welding with argon shielding to prevent oxidation. |
| Heat Treatment | Solution annealing (1040–1120°C) to restore corrosion resistance. |
| Surface Treatment | Pickling, polishing, or galvanizing per application needs. |
