Audited Supplier Introduction
Stellite welding rods are a popular choice for industrial applications that require high levels of wear and corrosion resistance. Made from a cobalt-chromium alloy, Stellite is known for its excellent mechanical properties, including high hardness, strength, and toughness. Composition
Stellite welding rods are made from cobalt-based alloys with varying compositions depending on the specific grade.
| Grade | Carbon (C) | Manganese (Mn) | Silicon (Si) | Chromium (Cr) | Nickel (Ni) | Molybdenum(Mo) | Tungsten (W) | Cobalt(Co) | Iron(Fe) |
|---|---|---|---|---|---|---|---|---|---|
| Stellite 1 | 2.2-2.8% | - | 2.0% max | 29.0-33.0% | 3.0% max | 1% max | 11.0-14.0% max | Bal. | 3% max |
| Stellite 6 | 0.9-1.4% | 1.0% max | 1.5% max | 27.0-31.0% | 3.0% max | 1.5% max | 3.5-5.5% max | Bal. | 3% max |
| Stellite 12 | 1.1-1.7% | 1.0% max | 1.0% max | 28.0-32.0% | 3.0% max | - | 7.0-9.5% max | Bal. | 3% max |
| Stellite 21 | 1.0-1.4% | 1.0% max | 1.0% max | 29.0-33.0% | 3.0% max | - | 4.0-6.0% max | Bal. | 3% max |
Advantages
Stellite welding rods offer several advantages over other materials:
Applications
Stellite welding rods are commonly used in a range of industries, including aerospace, automotive, and manufacturing. They are particularly well-suited for use in applications where components are subject to high levels of wear, such as valve seats, pump shafts, and cutting tools.
| Application | Description |
|---|---|
| Valve Seats | Stellite welding rods are often used to make valve seats for engines and other machinery, where high wear resistance is required. |
| Pump Shafts | Stellite welding rods can be used to make pump shafts, which are subject to high levels of wear and corrosion. |
| Cutting Tools | Stellite welding rods can be used to make cutting tools such as saw blades and drill bits |
Stellite welding rods come in different grades, each with specific compositions and properties that make them suitable for various applications. The following section highlights the differences in the applications of four common grades of Stellite welding rods.
Stellite 1: This grade is known for its excellent wear resistance, making it suitable for use in high-temperature and high-stress environments. It is commonly used in valve seats, cutting tools, and metal-forming dies.
Stellite 6: This grade is a versatile option that offers good resistance to wear, corrosion, and oxidation. It is commonly used in valve seats, bearings, and pump shafts, as well as in welding and hard-facing applications.
Stellite 12: This grade is designed for use in severe wear and corrosion environments. It is commonly used in saw teeth, valve seats, and cutting tools, as well as in the aerospace industry for turbine blades and other high-stress components.
Stellite 21: This grade is specifically designed for applications that require high levels of corrosion resistance. It is commonly used in chemical processing, pulp and paper production, and marine environments.
The choice of Stellite welding rod grade depends on the specific application and the properties required. Stellite 1 is ideal for high-temperature and high-stress environments, Stellite 6 is a versatile option that offers good resistance to wear, corrosion, and oxidation, Stellite 12 is suitable for severe wear and corrosion environments, and Stellite 21 is designed for applications that require high levels of corrosion resistance.
