SSP manufactures Alloy 400/405 and C-276 tube fittings, pipe fittings, and valves for instrumentation, utility, control and process applications. SSP products meet all industry standards and can significantly improve the time and cost of installing, operating and maintaining systems. Our goal is to be the installer’s supplier of choice.
Hastelloy C276 Fittings
Hastelloy C276 is a superalloy comprised of nickel, molybdenum, chromium, and tungsten. It is the most widely used Hastelloy nickel alloy on the market. The molybdenum and nickel content of Hastelloy C276 make it highly corrosion resistant in extremely harsh conditions, and the chromium creates a protective surface layer to prevent oxidization. Hastelloy C276 is particularly valuable for welding applications, as its low carbon content reduces carbide precipitation, thereby ensuring optimal corrosion resistance without the need for additional treatment after welding.
Characteristics and Benefits of Hastelloy C276
Hastelloy C276 offers a number of beneficial characteristics, including:
- Superior corrosion resistance in harsh conditions and reducing atmospheres
- Excellent resistance to strong oxidizing solutions
- Low carbon content for minimal carbide precipitation during welding
- Exceptional resistance to localized stress-corrosion, pitting, and cracking
- Unique resistance to chlorine-based corrosive materials
Industries and Applications That Use Hastelloy C276
Due to its exceptional corrosion resistance, Hastelloy C276 is particularly valuable for environments with extreme conditions, such as marine applications, chemical manufacturing, wastewater treatment, and natural gas production.
What Is Alloy 400?
Alloy 400, also known as Monel 400, is a nickel-copper alloy that has been in production for over 100 years. It is highly corrosion resistant and can withstand temperatures up to 1000°F, making it one of the most popular corrosion-resistant alloys on the market. Alloy 400 is particularly valued for its ability to operate in extremely cold conditions without becoming brittle. It can be worked using both hot and cold processes, but the cold-worked material exhibits better machinability. Alloy 400 exhibits some magnetic properties and should be avoided for applications that require non-magnetic materials.
Characteristics and Benefits of Alloy 400
- Exceptional resistance to corrosion and cracking in seawater, brackish water, and freshwater
- Excellent temperature resistance
- Superior resistance to an array of chemicals, including de-aerated hydrochloric and hydrofluoric acids, chlorides, salts, and alkalis
- Reliable mechanical properties in a large range of temperatures from sub-zero to 1000°F
Alloy 400 Industries and Applications
Alloy 400’s exceptional corrosion and temperature resistance make it especially useful for chemical manufacturing and marine applications. It is often used in components that are exposed to extremely harsh conditions and stress, such as fasteners and fixtures, shafts, springs, pumps, valves, containers, pipes, and heat exchangers.
What Is Alloy 405?
Similar to Alloy 400, Alloy 405 is a nickel-copper alloy. It is considered the machine grade of Alloy 400, and exhibits greater machinability due to its higher sulfur content. For the most part, Alloy 405 exhibits the same temperature and corrosion resistance as Alloy 400, and also performs particularly well in sub-zero temperatures. The primary difference between Alloy 400 and Alloy 405 is its machinability. It is typically used for automatic screw machines.
Characteristics and Benefits of Alloy 405
- Enhanced machinability
- Exceptional resistance to corrosion and cracking in seawater, brackish water, and freshwater
- Excellent temperature resistance
- Superior resistance to an array of chemicals, including de-aerated hydrochloric and hydrofluoric acids, chlorides, salts, and alkalis
- Reliable mechanical properties in a broad range of temperatures from sub-zero to 1000°F
Industries and Applications That Use Alloy 405
Alloy 405 is valued for its high machinability and is typically used in automatic screw machines and as a chip breaker in machining applications. It is not generally recommended for other applications.
