Overview & Importance: Why Choose ASTM A403 WP304H / CR304H (UNS S30409) Butt-Weld Pipe Fittings
Butt-Weld Pipe Fittings manufactured from ASTM A403 WP304H / CR304H (UNS S30409) are critical components for high-integrity piping systems operating at elevated temperatures. This high-carbon austenitic stainless steel (SS 304H) is a variant of standard 304 stainless steel, specifically engineered to provide superior strength and creep resistance at service temperatures above 525°C (975°F). The controlled carbon content in 304H promotes carbide precipitation, which enhances its creep rupture properties, making it indispensable for pressure-retaining parts in high-temperature environments. The Butt-Weld connection provides a permanent, leak-proof joint with full penetration welds, crucial for stable and safe operation under thermal stress.
As a major global WP304H Butt-Weld Fittings manufacturer and UNS S30409 supplier in Mumbai, DIPTI METAL INDUSTRIES provides a diverse range of these essential fittings. Our inventory covers Butt-Weld Elbows, Butt-Weld Tees, Butt-Weld Reducers, Butt-Weld Caps, and Butt-Weld Stub Ends, all conforming to ASME B16.9. These fittings ensure optimal performance across a spectrum of high-temperature operating conditions, from power plant steam lines to chemical reactor components. The inherent advantages of WP304H Butt-Weld fittings include:
- Superior High-Temperature Strength: Specifically designed for enhanced creep and stress rupture strength at elevated temperatures, surpassing standard 304L.
- Good General Corrosion Resistance: Retains the general corrosion resistance of Type 304 in many environments.

Material Properties: ASTM A403 WP304H / CR304H (UNS S30409)
ASTM A403 WP304H / CR304H refers to **Stainless Steel 304H**, specifically designated as UNS S30409. The 'H' suffix indicates a controlled, higher carbon content (0.04-0.10%) compared to standard 304 (UNS S30400) or low-carbon 304L (UNS S30403). This increased carbon is intentionally added to enhance the alloy's elevated-temperature strength, particularly its creep and stress rupture properties, making it ideal for pressure-containing applications in environments where temperatures exceed approximately 525°C (975°F). While retaining the general corrosion resistance of Type 304, its primary advantage lies in its superior mechanical performance under sustained high heat. It is also known by its European equivalent EN 1.4948 (ASTM A182 F304H forgings).
DIPTI METAL INDUSTRIES, as a leading UNS S30409 Butt-Weld Fittings supplier, ensures all materials meet stringent international standards and offer full material traceability. We also supply other high-temperature stainless steel grades like WP309H and WP310H, as well as general-purpose WP304 and WP310S fittings.
Key Characteristics of WP304H / CR304H (UNS S30409):
- Composition: A chromium-nickel austenitic stainless steel with a controlled high carbon range (0.04-0.10%). Typical composition includes Chromium (18-20%) and Nickel (8-10.5%).
- Enhanced Creep & Stress Rupture Strength: The defining characteristic, directly attributed to its higher carbon content, making it suitable for applications under prolonged stress at elevated temperatures. This is vital in power generation.
- Good General Corrosion Resistance: Offers similar corrosion resistance to Type 304 in non-aggressive environments. However, its higher carbon can make it susceptible to sensitization and intergranular corrosion in specific corrosive media after welding if not properly heat treated or when operating in the sensitization temperature range.
- Good Oxidation Resistance: Resists oxidation in continuous service up to approximately 900°C (1650°F), similar to standard 304.
- Mechanical Properties: Provides good strength at ambient temperatures and maintains superior strength at elevated temperatures compared to 304L.
- Weldability: Generally weldable by standard fusion methods. For applications where post-weld solution annealing is not practical, or where prolonged exposure to the sensitization temperature range occurs in service, stabilized grades like F347H or F321H, or low-carbon grades like 304L, may be preferred.
- International Equivalents: Widely known as SS 304H, and its European equivalent is often specified as EN 1.4948 for high-temperature applications.
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 WP304H Butt-Weld Fittings manufacturer in Mumbai ensures meticulous control over material properties, including those comparable to 1.4845 (310S).

ASTM A403 WP304H / CR304H (UNS S30409) Butt-Weld Fittings — Frequently Asked Questions
ASTM A403 WP304H Butt-Weld Pipe Fittings (also known as CR304H or UNS S30409, commonly Stainless Steel 304H) are primarily used in critical high-temperature, pressure-retaining piping systems. Their main application is where enhanced strength and creep resistance are required at service temperatures exceeding 525°C (975°F), such as in power generation, chemical processing, and industrial furnace components.
The key to UNS S30409 Butt-Weld Fittings' high-temperature performance is its controlled, higher carbon content (0.04-0.10%). This carbon promotes beneficial carbide precipitation which significantly enhances the material's creep and stress rupture strength at elevated temperatures, preventing deformation and failure under long-term thermal stress. This differentiates it from standard 304 or 304L, making it a robust choice for power plant components and Incoloy 800H/HT applications.
At Dipti Metal Industries, we supply a comprehensive range of Butt-Weld Fittings in WP304H / CR304H (UNS S30409). 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 WP304H Butt-Weld Pipe Fittings are generally weldable, specific considerations apply due to the higher carbon content. To maintain the enhanced high-temperature properties and avoid potential issues, it is recommended to use matching filler metals like ER308H. For applications requiring post-weld heat treatment or where service conditions involve prolonged exposure to the sensitization temperature range, stabilized grades (WP347H, WP321H) or low-carbon alternatives (WP304L) might be considered if high-temperature strength isn't the absolute highest priority.
Absolutely. As a leading manufacturer and exporter, we guarantee full traceability for all our products. Every shipment of CR304H / UNS S30409 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.
