Material Properties: ASTM A403 WP309 / CR309 (UNS S30900)
ASTM A403 WP309 / CR309 refers to **Stainless Steel 309**, specifically designated as UNS S30900. This alloy is a high-chromium, high-nickel austenitic stainless steel primarily used for its excellent performance in high-temperature, oxidizing environments. Compared to more common grades like 304 or 316, SS 309 contains significantly higher chromium (22-24%) and an elevated nickel content (11-13%). This composition provides superior resistance to oxidation and scaling, as well as improved strength at elevated temperatures. It is a workhorse material in applications requiring thermal stability and resistance to hot gas attack, with continuous service temperature limits extending up to 1093°C (2000°F). It is also known by its European equivalent EN 1.4828 or similar to 1.4845 (310S) in high-temp performance but with different Cr/Ni balance.
DIPTI METAL INDUSTRIES, as a leading UNS S30900 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, WP310, WP310H, and other High Temperature Alloys.
Key Characteristics of WP309 / CR309 (UNS S30900):
- Composition: A high-chromium, high-nickel austenitic stainless steel. Typical composition includes Chromium (22-24%), Nickel (11-13%), and Carbon (max 0.08%).
- Excellent Oxidation Resistance: The high chromium content forms a stable, protective oxide layer, providing superb resistance to oxidation and scaling in air up to 1093°C (2000°F).
- High Elevated-Temperature Strength: Maintains good mechanical properties, including tensile strength and creep strength, at high service temperatures, outperforming standard 304 and 316.
- Resistance to Thermal Fatigue: Enhanced resistance to cracking caused by cyclic heating and cooling, which is crucial in fluctuating temperature environments.
- Good General Corrosion Resistance: Offers good resistance to various corrosive media, similar to Type 304, in less aggressive chemical environments, but it is primarily selected for its high-temperature properties.
- Good Weldability: Readily weldable using conventional techniques; generally uses ER309 or ER309L filler metals.
- International Equivalents: Widely known as SS 309, and its European equivalent is often EN 1.4828. Other high-temperature steel standards like 1.7386 (alloy steel) or 1.4903 (F91) are for different 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 WP309 Butt-Weld Fittings manufacturer in Mumbai ensures meticulous control over material properties, including those comparable to 1.4550 (347) for heat resistance.

ASTM A403 WP309 / CR309 (UNS S30900) Butt-Weld Fittings — Frequently Asked Questions
ASTM A403 WP309 Butt-Weld Pipe Fittings (also known as CR309 or UNS S30900, commonly Stainless Steel 309) are primarily used in critical high-temperature and oxidizing environments. Their main application is where excellent oxidation resistance and elevated temperature strength are required, such as in furnace components, heat treatment equipment, kiln linings, and other thermal processing applications operating up to 1093°C (2000°F).
The superior high-temperature properties of UNS S30900 Butt-Weld Fittings stem from its high chromium (22-24%) and nickel (11-13%) content. The high chromium promotes the formation of a stable, adherent oxide layer, providing exceptional resistance to oxidation and scaling at elevated temperatures. The nickel contributes to the overall elevated temperature strength and ductility, preventing embrittlement. This makes it significantly more resistant to heat than grades like WP304.
At Dipti Metal Industries, we supply a comprehensive range of Butt-Weld Fittings in WP309 / CR309 (UNS S30900). 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 both ASTM A403 WP309 Butt-Weld Pipe Fittings and 310S are high-temperature austenitic stainless steels, 310S (UNS S31008) generally offers even better oxidation and corrosion resistance at higher temperatures due to its higher chromium and nickel content. WP309 serves as an excellent intermediate choice, offering superior performance over 304/304H (WP304H) while being more economical than 310S for many high-temperature applications up to its specified limits.
Absolutely. As a leading manufacturer and exporter, we guarantee full traceability for all our products. Every shipment of CR309 / UNS S30900 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.
