ASTM A403 WP304L Elbow | SA403 WP304/L Elbow | ASME B16.9
We are a professional manufacturer and supplier of ASTM A403 WP304L elbows, SA403 WP304/L elbows, and ASME B16.9 elbows in China. Our high-quality products cater to industries such as petrochemical, chemical processing, food and beverage, oil and gas, and pharmaceuticals.
What is ASTM A403 WP304/L Material?
ASTM A403 WP304/L refers to the dual-certified grade of stainless steel. The “W” indicates wrought austenitic stainless steel, and “P” denotes piping grade. This material is commonly used in piping systems requiring excellent corrosion resistance and superior weldability.
Key Features of WP304/304L Stainless Steel:
- 304 Stainless Steel: A versatile “18/8” stainless steel with excellent forming and welding characteristics, widely used across industries.
- 304L Stainless Steel: A low-carbon version of 304 stainless steel, preventing carbide precipitation during welding and suitable for corrosive environments.
Dual-Certified 304/304L Material:
WP304/304L ensures that the chemical composition meets 304L standards, while mechanical properties comply with 304 grade requirements for superior performance.
ASTM A403 WP304/304L Chemical Composition:
| Element | 304 (%) | 304L (%) |
|---|---|---|
| Carbon (C) | ≤ 0.08 | ≤ 0.03 |
| Manganese (Mn) | ≤ 2.0 | ≤ 2.0 |
| Silicon (Si) | ≤ 0.75 | ≤ 0.75 |
| Phosphorus (P) | ≤ 0.045 | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 | ≤ 0.030 |
| Chromium (Cr) | 18.0 – 20.0 | 18.0 – 20.0 |
| Nickel (Ni) | 8.0 – 12 | 8.0 – 12.0 |
ASTM A403 WP304/304L Mechanical Properties:
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (HRB) |
|---|---|---|---|---|
| 304 | ≥ 515 | ≥ 205 | ≥ 40 | ≤ 92 |
| 304L | ≥ 485 | ≥ 170 | ≥ 40 | ≤ 92 |
ASME B16.9 Elbow
An elbow is a pipe fitting used to change the flow direction in piping systems. Common types include:
- 90° Elbow: Changes flow direction by 90°.
- 45° Elbow: Adjusts flow by 45°.
- 180° Elbow: Reverses flow direction.
- Special Degrees: Available for customized requirements (e.g., 22.5°).
ASME B16.9 Standard Features:
- Covers butt-welding fittings from NPS ½ to NPS 48.
- Includes dimensional tolerances, testing, and marking.
