ASTM A213 / ASME SA213 TP304 Stainless Steel Seamless Tube
Overview
TP304 stainless steel is primarily composed of iron (Fe), chromium (Cr), and nickel (Ni). It typically contains a minimum of 18% chromium and 8% nickel, providing its excellent corrosion resistance properties.The mechanical properties of TP304 include tensile strength, yield strength, elongation, and hardness. These properties are essential for determining the material's strength and its ability to withstand various stresses.
ASTM A213 TP304 specifies the dimensions, tolerances, and sizes of the tubes. It provides requirements for the outside diameter (OD), wall thickness, and length of the tubes used in boiler, superheater, and heat-exchanger applications.
TP304 tubes may undergo different heat treatments such as normalization, quenching, and tempering to enhance their mechanical properties and improve their resistance to stress corrosion cracking.The standard defines various tests and inspections to ensure the quality of TP304 tubes. These include hydrostatic testing, non-destructive examination (such as eddy current or ultrasonic testing), and tensile tests.
