This passage explains the differences between two main types of stainless steel: duplex stainless steel and austenitic stainless steel.This passage explains the differences between two main types of stainless steel: duplex stainless steel and austenitic stainless steel. It will cover three aspects to highlight the distinctions between the two categories.
- Chemical Composition
The chemical composition is the most obvious difference between duplex and austenitic stainless steel. Duplex steel is typically composed of approximately 22% chromium and 5% nickel, while austenitic steel contains around 18% chromium and 8% nickel.
- Welding Process
The welding process for duplex and austenitic stainless steel differs significantly. Due to its high carbon content, special welding methods are required to prevent cracking or other damage when welding duplex steel. In contrast, austenitic steel, which has a lower carbon level, is much easier to weld.
- Application
Duplex stainless steel is commonly used in applications that require high strength and corrosion resistance, such as the oil and gas industry.
On the other hand, austenitic stainless steel is typically used in applications that require ductility and weldability, such as the food and beverage industry.
Both austenitic and duplex stainless steels are versatile materials that offer a range of processed features for engineering applications. Ultimately, the choice of stainless steel depends on the specific application needs.
