Ni-Resist Castings

Introduction

At Calmet, we understand the importance of corrosion resistance in critical applications. As a leading supplier in the industry, we specialize in providing high-quality ni resist castings that offer exceptional corrosion resistance, excellent mechanical properties, and superior performance in demanding environments.
Ni-Resist castings, also known as nickel-iron castings. It is a type of cast iron that contains significant amounts of nickel and chromium.
Ni-Resist castings typically contain around 14-30% nickel and 1-5% chromium, along with other elements such as carbon, silicon, and molybdenum.
The exact composition may vary depending on the specific grade and application requirements.

Types of Ni Resist

Ni-Resist castings are available in different grades or types, each offering specific properties and characteristics to suit various applications. Here are some commonly used types of Ni-Resist castings:

Type I Ni-Resist (Gray Iron)

Type I Ni-Resist castings are primarily made of gray iron with a small addition of nickel and chromium. They provide good resistance to corrosion and are often used in applications such as pump housings, valves, and fittings that require both strength and corrosion resistance.

Type II Ni-Resist (Austenitic)

Type II Ni-Resist castings contain higher amounts of nickel and chromium, which promote the formation of an austenitic matrix structure. They offer superior corrosion resistance in harsh environments and are commonly used in chemical processing, marine equipment, and similar applications.

Type D Ni-Resist (Duplex)

Type D Ni-Resist castings have a duplex microstructure, consisting of both austenite and ferrite phases. This type of Ni-Resist offers an excellent combination of strength, corrosion resistance, and thermal stability. Type D castings are well-suited for applications in high-

Type IV Ni-Resist (Austenitic/Ferritic)

Type IV Ni-Resist castings have a dual austenitic/ferritic microstructure, providing a balance between strength, ductility, and corrosion resistance. They are widely used in applications where both mechanical properties and corrosion resistance are important, such as engine components, pump housings, and hydraulic systems.
When selecting a specific type of Ni-Resist casting Calmet is your trusted partner, it’s crucial to consider the application requirements, including the desired corrosion resistance, mechanical properties, and operating conditions. With our extensive expertise, commitment to quality, and personalized service, we provide you with the castings you can rely on for your critical applications.
Ni-Resist castings widely used in various industries including automotive, marine, chemical processing, power generation, and oil and gas. Due to their excellent corrosion resistance, high-temperature strength, and non-magnetic with good mechanical properties they are commonly used in engine components, exhaust systems, pump and valve bodies, turbine housings, heat exchangers, and other critical parts.

Properties

Ni-Resist castings from Calmet are engineered to deliver exceptional mechanical properties. Ni-Resist castings possess high tensile strength, toughness, and wear resistance. They also have low thermal expansion, which reduces the risk of thermal stress and cracking. These properties make Ni-Resist castings suitable for applications requiring high strength and durability, such as engine components, pump housings, and hydraulic systems.

Corrosion resistance

One of the primary advantages of Ni-Resist castings is their exceptional resistance to corrosion. They offer resistance to a wide range of corrosive environments, including acidic, alkaline, and marine environments. This makes them suitable for applications in chemical processing, marine equipment, pumps, valves, and similar industries.

Heat resistance

Ni-Resist castings exhibit excellent high-temperature strength and thermal stability. They can withstand elevated temperatures without significant loss of mechanical properties, making them suitable for applications in heat ex-changers, furnace components, exhaust manifolds, and other high-temperature environments.
