Material Properties: ASTM A403 WP20CB / CR20CB (UNS N08020)
ASTM A403 WP20CB / CR20CB refers to the highly corrosion-resistant **nickel-iron-chromium Alloy 20**, specifically designated as UNS N08020. This alloy, widely known by its brand name Carpenter 20Cb-3®, is designed for exceptional resistance to aggressive chemical environments, particularly sulfuric acid, nitric acid, and various chloride solutions. Its composition includes a significant amount of nickel, chromium, molybdenum, copper, and niobium, which together provide a robust defense against stress corrosion cracking, pitting, and intergranular attack.
DIPTI METAL INDUSTRIES, as a leading UNS N08020 Butt-Weld Fittings supplier, ensures all materials meet stringent international standards and offer full material traceability. We also supply other Hastelloy G3 fittings, Butt-Weld Nickel Chrome Moly Copper fittings, and various High Temperature Alloys like Incoloy 825.
Key Characteristics of WP20CB / CR20CB (UNS N08020):
- Composition: A nickel-iron-chromium alloy with additions of molybdenum (Mo), copper (Cu), and niobium (Nb). The precise balance of these elements, especially the relatively high nickel (32-38%) and chromium (19-21%) with molybdenum and copper, imparts its superior corrosion resistance.
- Exceptional Sulfuric Acid Resistance: Offers outstanding corrosion resistance to boiling sulfuric acid up to 40% concentration and excellent resistance in various other concentrations and temperatures, including hot dilute sulfuric acid.
- High Resistance to Chloride Stress Corrosion Cracking (SCC): Its high nickel content is particularly effective in preventing chloride-induced SCC, a common issue in process industries.
- Resistance to Intergranular Corrosion: Niobium (Nb) stabilization effectively inhibits carbide precipitation during welding and subsequent exposure to critical temperature ranges, thus maintaining resistance to intergranular attack without post-weld annealing.
- Good Resistance to Pitting and Crevice Corrosion: Molybdenum and chromium contribute to enhanced resistance against localized corrosion in many aggressive oxidizing and reducing environments.
- Good Mechanical Properties: Possesses high strength and ductility, performing reliably under pressure and stress.
- Good Weldability: Can be readily welded using conventional methods, thanks to its niobium content.
- International Equivalents: Often referred to as Alloy 20, Carpenter 20Cb-3®, or comparable to EN 1.4541 (SS 321) in stabilization principle, but with vastly superior corrosion resistance.
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).

ASTM A403 WP20CB / CR20CB (UNS N08020) Butt-Weld Fittings — Frequently Asked Questions
ASTM A403 WP20CB Butt-Weld Pipe Fittings (also known as CR20CB or UNS N08020, commonly Alloy 20) are primarily used in critical, high-pressure, and highly corrosive piping systems that require exceptional resistance to sulfuric acid, nitric acid, and various chloride environments. They are ideal for applications where stress corrosion cracking (SCC) and intergranular corrosion are significant concerns, such as in chemical processing and pharmaceutical industries.
The excellent resistance of UNS N08020 Butt-Weld Fittings to sulfuric acid stems from its optimized chemical composition, including high levels of nickel, chromium, molybdenum, and copper. This alloy is specifically engineered to withstand various concentrations and temperatures of sulfuric acid, a property that sets it apart from many other stainless steels and nickel alloys. It also offers superior resistance to chloride stress corrosion cracking, making it a robust choice for these aggressive environments.
At Dipti Metal Industries, we supply a comprehensive range of Butt-Weld Fittings in WP20CB / CR20CB (UNS N08020). 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.
Yes, ASTM A403 WP20CB / CR20CB (UNS N08020) Butt-Weld Pipe Fittings are designed to resist intergranular corrosion. This is achieved through niobium stabilization, which ties up carbon and prevents the formation of chromium carbides at grain boundaries during welding. This allows the fittings to be used in the as-welded condition without the need for post-weld solution annealing, ensuring optimal performance and integrity in corrosive service.
Absolutely. As a leading manufacturer and exporter, we guarantee full traceability for all our products. Every shipment of CR20CB / UNS N08020 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.
