Which Material Of Stainless Steel Ball Valve Is More Durable? Common Material Analysis!

When choosing valves, the most common one we see is 1 Piece Ball Valve. However, stainless steel also has its own quality. Common stainless steels used to make stainless steel ball valves include 304 stainless steel, austenitic stainless steel, etc. Which quality is better and more durable?

1、 Stainless steel and 304 stainless steel

Due to the particularity and differences of the application environment, the selection of materials for valve manufacturing must be very particular. Austenitic stainless steel and 304 stainless steel are widely used stainless steel materials. The former has strong toughness and plasticity, and the addition of other elements such as sulfur and calcium can produce good cutting performance. However, 304 stainless steel has more outstanding corrosion resistance and is often used in kitchen wastewater pipelines and industrial wastewater treatment devices.

2、 Heat resistant steel and low temperature resistant steel

The working environment temperature difference of stainless steel ball valves can reach up to 1000 degrees Celsius, with low temperatures as low as -296 degrees Celsius and high temperatures as high as over 800 degrees Celsius. Therefore, choosing which material of stainless steel valve is more durable also depends on its heat resistance and low temperature resistance. Pipeline systems above 300 degrees Celsius use special heat-resistant steel, while low-temperature steel is suitable for temperatures ranging from -29 to -296 degrees Celsius, with -196 to -296 being ultra-low temperature environments. The temperature resistance of valve materials is very important. In low temperature environments, material brittleness increases and volume shrinks, which can easily lead to valve leakage. Therefore, it is necessary to choose valves made of suitable materials according to the ambient temperature.

To ensure the service life of stainless steel ball valves, it is important to purchase the valve that is most suitable for the working environment. Otherwise, insufficient pressure bearing capacity and excessive friction can cause premature damage to the valve.
