Product Description
Introduction
409 stainless steel is a ferritic stainless steel commonly used in machinery, construction and other projects. Because of the existence of austenite grains, its mechanical properties have been greatly improved. And due to the addition of a lot of alloy elements, the strength and hardness are also greatly improved.

Applications
Advantages
Characteristics
409 stainless steel has high corrosion resistance and high temperature resistance. It can be used in the exhaust system to increase the service life of 409 stainless steel and save energy. And because of its high temperature resistance, it can realize high-efficiency exhaust system and reduce the thickness of exhaust system, so as to save energy and reduce exhaust gas emission. 409 stainless steel has low cost, high yield and easy replacement, so it is also used by many people now. It is generally used for automobile exhaust emission device to ensure the exhaust emission of automobile and the good use of automobile tail parts. Because 409 stainless steel has so many characteristics, it is often used in many other industries. For example, domestic heating furnaces, farm devices, fuel filters and so on need high temperature resistant devices.
