Material Properties: ASTM A403 WP304L / CR304L (UNS S30403)
ASTM A403 WP304L / CR304L refers to **Stainless Steel 304L**, specifically designated as UNS S30403. The 'L' suffix indicates a low-carbon version of standard 304 stainless steel, with a maximum carbon content of 0.03%. This reduced carbon content is the key differentiator, providing superior resistance to intergranular corrosion in the heat-affected zone (HAZ) after welding. This characteristic is particularly valuable for applications where post-weld solution annealing is either impractical or impossible, allowing components to be used in the as-welded condition without compromising corrosion resistance. SS 304L retains the excellent general corrosion resistance, good formability, and superb weldability of Type 304. It is also known by its European designation 1.4307.
DIPTI METAL INDUSTRIES, as a leading UNS S30403 Butt-Weld Fittings supplier, ensures all materials meet stringent international standards and offer full material traceability. We also supply other stainless steel grades like WP304 and WP316, as well as low-carbon versions such as 316L pipes.
Key Characteristics of WP304L / CR304L (UNS S30403):
- Composition: A chromium-nickel austenitic stainless steel with a very low carbon content (max 0.03%). Typical composition includes Chromium (18-20%) and Nickel (8-13%).
- Resistance to Intergranular Corrosion: The primary advantage. Low carbon content prevents carbide precipitation in the HAZ during welding, eliminating susceptibility to intergranular corrosion (also known as weld decay).
- Excellent Weldability: Can be welded by all standard fusion methods without the need for post-weld annealing, making it highly versatile for fabricated structures.
- Good General Corrosion Resistance: Offers resistance to a wide range of corrosive media, similar to Type 304, in atmospheric, fresh water, and mild chemical environments. It performs well in many chemical processing, food, and dairy applications.
- Good Formability: High ductility allows it to be easily drawn, stretched, or spun into complex shapes, making it ideal for various fabrication methods.
- Non-Magnetic: Typically non-magnetic in the annealed condition.
- Mechanical Properties: Slightly lower mechanical strength than 304 due to lower carbon, but still suitable for a broad range of pressure-containing applications.
- International Equivalents: Widely known as SS 304L, and its European equivalent is 1.4307. Also referenced in many national standards.
Note: Detailed chemical analysis and specific mechanical properties for each batch and grade are provided in the EN 10204 3.1 Mill Test Certificate (MTC). Our expertise as a top WP304L Butt-Weld Fittings manufacturer in Mumbai ensures meticulous control over material properties, including those comparable to 1.4301.

ASTM A403 WP304L / CR304L (UNS S30403) Butt-Weld Fittings — Frequently Asked Questions
ASTM A403 WP304L Butt-Weld Pipe Fittings (also known as CR304L or UNS S30403, commonly Stainless Steel 304L or 1.4307) are primarily used in welded applications where resistance to intergranular corrosion in the heat-affected zone is crucial and post-weld annealing is not feasible. This makes them ideal for industries like chemical processing, food & beverage, and pharmaceutical, where extensive welding of stainless steel components is common.
The primary advantage of UNS S30403 Butt-Weld Fittings over standard 304 is its very low carbon content (max 0.03%). This low carbon virtually eliminates the risk of carbide precipitation in the heat-affected zone during welding, thereby providing superior resistance to intergranular corrosion without the need for post-weld solution annealing. This simplifies fabrication and reduces costs for welded structures, especially for applications like 316L pipes where similar benefits are desired.
At Dipti Metal Industries, we supply a comprehensive range of Butt-Weld Fittings in WP304L / CR304L (UNS S30403). This includes Elbows (45°, 90°, 180° - Long and Short Radius), Tees (Equal and Reducing), Reducers (Concentric and Eccentric), Caps, Stub Ends (Lap Joint Type A & B), and Crosses. These configurations are available in various sizes (NPS) and wall thickness schedules to meet diverse project requirements, conforming to ASME B16.9. For broader options, refer to our main Butt-Weld Pipe Fittings page.
While ASTM A403 WP304L Butt-Weld Pipe Fittings exhibit good oxidation resistance at temperatures up to 870°C (1598°F), their low carbon content provides slightly lower strength at elevated temperatures compared to standard 304 or high-carbon 304H. For applications requiring superior strength and creep resistance above 525°C (975°F), WP304H or other high-temperature alloys would be more appropriate.
Absolutely. As a leading manufacturer and exporter, we guarantee full traceability for all our products. Every shipment of CR304L / UNS S30403 Butt-Weld Fittings includes the mandatory EN 10204 3.1 Mill Test Certificate (MTC). This certificate provides comprehensive details on the precise chemical analysis, mechanical test results, critical heat treatment parameters, and all relevant inspection data of the specific heat batch used for your fittings, ensuring full compliance with international standards and project specifications, as well as adherence to our stringent Quality Assurance protocols. This applies to a wide range of our offerings, from API 5L X80 pipes to specialized UNS N06002 welded pipes.
