At ZYTC Alloy, we specialize in providing high-performance Nickel alloy solutions, with Alloy 400 being a cornerstone of our product portfolio. Our recent successful delivery of ASTM B564 Alloy 400 Forged Rings (specifications 665*470*55mm and 508*263*55mm) to a client in Italy underscores our commitment to global quality standards and reliable supply. This transaction exemplified our standardized, procedural, and professional production and inspection processes, ensuring every product passes stringent testing before delivery.
Alloy 400, also commonly known as Monel 400, is a solid-solution strengthened nickel-copper alloy renowned for its exceptional corrosion resistance, high strength, and excellent toughness across a wide temperature range.
Chemical Composition of Alloy 400:
The outstanding properties of Alloy 400 stem from its fundamental composition. It is primarily comprised of nickel (min. 63%) and copper (approximately 28-34%), with small additions of iron, manganese, carbon, and silicon. This blend grants it superior performance in corrosive environments where common steels and even some stainless steels would fail.
| C | Mn | S | Si | Ni | Cu | Fe |
| 0.3 max | 2.0 max | 0.24 max | 0.5 max | 63 min | 28-34 | 2.5 max |
Mechanical Properties of Alloy 400:
Alloy 400 offers a robust combination of mechanical properties, making it suitable for forged components, fasteners, and valve trim. It possesses good tensile and yield strength, maintains ductility even at sub-zero temperatures, and is not susceptible to chloride-induced stress corrosion cracking. Its machinability is similar to that of low-alloy steels, allowing for the fabrication of complex parts.
| Form | Condition | Tensile (Ksi) | 0.2% Yield (Ksi) | Elongation % | Hardness (HRB) |
| Bar | Annealed | 75-90 | 25-50 | 60-35 | 60-80 |
| Bar | Cold drawn | 84-120 | 55-100 | 40-22 | 20-85 |
| Plate | Annealed | 70-85 | 28-50 | 50-35 | 60-76 |
| Sheet | Annealed | 70-85 | 30-45 | 45-35 | 65-80 |
| Pipe | Annealed | 70-85 | 25-45 | 50-35 | 75 max |
Key Applications of Alloy 400:
The versatility of Alloy 400 makes it indispensable across critical industries. Its excellent resistance to seawater corrosion, acidic environments, and alkaline solutions drives its use in:
-
Marine Engineering: Pump shafts, marine fixtures, valve components, and seawater heat exchangers.
-
Chemical and Hydrocarbon Processing: Equipment handling hydrofluoric acid, sulfuric acid, alkalies, and solvents.
-
Oil & Gas: Wellhead components, fasteners, and processing equipment in sour gas environments.
-
Other Industries: Feedwater heaters, evaporator baskets, and musical instrument strings.
