TP304L VS TP304 Chemical Composition
Carbon content: The upper limit of carbon content of TP304L is 0.035% or less (such as ≤0.03% specified in some standards), while the carbon content of TP304 is relatively high.
Nickel content: Although both contain a certain amount of nickel, the specific range may be different. Nickel helps to improve the corrosion resistance of stainless steel.
TP304L VS TP304 Mechanical properties
Yield strength and tensile strength:
The minimum values of yield strength and tensile strength of TP304 are generally higher than those of TP304L. This means that TP304 may show higher strength when subjected to the same external force.
Corrosion resistance: Due to the lower carbon content of TP304L, the precipitation of chromium carbide is reduced, thereby improving its corrosion resistance. Therefore, TP304L may be more suitable in situations where higher corrosion resistance is required.
TP304L VS TP304 Application Fields
TP304: Due to its good corrosion resistance and mechanical properties, TP304 stainless steel pipes are widely used in many fields such as petroleum, chemical industry, food processing, pharmaceutical, aerospace, etc. Especially in pipeline systems that need to withstand high pressure, high temperature and corrosive environment, TP304 stainless steel pipes can maintain stable performance.
TP304L: Due to its lower carbon content and higher corrosion resistance, TP304L stainless steel pipes have a wider range of applications in certain specific fields. For example, in applications that require frequent welding or exposure to harsh chemical environments, TP304L can provide better weldability and corrosion resistance. In addition, TP304L is also commonly used in the manufacture of equipment that needs to withstand high temperature and high pressure environments, such as heat exchangers, boiler components, etc.
