ASTM A1012 TP304; TP304L; TP304H; TP310S; TP310H Stainless Steel Tube Austenitic Stainless Fin Tube For Heat Exchanger
Introduction
Austenitic stainless steel tubes are widely used in heat exchangers due to their excellent corrosion resistance, high-temperature strength, and good weldability. ASTM A1012 covers various grades of stainless steel tubes, including TP304, TP304L, TP304H, TP310S, and TP310H. This article provides an overview of these materials, their specifications, chemical compositions, mechanical properties, and applications.
Material Specifications
The following are the specifications for the various grades of stainless steel tubes under ASTM A1012:
- TP304: Standard grade for general applications.
- TP304L: Low carbon version of TP304, suitable for welding.
- TP304H: Higher carbon content for improved high-temperature strength.
- TP310S: High alloy content for enhanced oxidation resistance.
- TP310H: Similar to TP310S but with higher carbon for better strength at elevated temperatures.
