SA 213 304H: Tubing Properties and Equivalents

At Gangsteel, a leading manufacturer and exporter of stainless steel products, we supply high-quality SA 213 TP 304H stainless steel tubing and related plates compliant with ASME SA 213 and ASTM A213 standards. SA 213 TP 304H, also known as AISI 304H, UNS S30409, or EN 1.4948, is a high-carbon austenitic stainless steel optimized for high-temperature service in boiler, superheater, and heat exchanger applications up to 1500°F (815°C). As the tube equivalent to SA 240 GR 304H plates, it shares identical composition and properties for seamless integration in high-temperature piping systems. This guide details the properties and equivalents of SA 213 TP 304H. Contact us at admin@gangsteel.com or explore our ASME SA240 Stainless sheet offerings.

Overview of SA 213 TP 304H Tubing

SA 213 TP 304H tubing is specified under ASME SA 213 for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. It is the direct tube equivalent to SA 240 GR 304H plates, both featuring 0.04-0.10% carbon for enhanced creep and rupture strength.The "TP" denotes "Tube," aligning with AISI 304H. Non-magnetic with a density of 8.00 g/cm³, SA 213 TP 304H tubes are used with SA 240 plates for fabricated systems like boilers and heat exchangers. See sa240 gr 304h for plate details.

Chemical Composition

The chemical composition of SA 213 TP 304H (equivalent to SA 240 GR 304H) is:

High carbon (0.04-0.10%) boosts creep resistance. See sa240 gr 304l for low-carbon variants.

Mechanical Properties

High strength at high temperatures (25.5 ksi allowable at 1000°F). See sa240 gr 304.

Physical Properties

• Density: 8.00 g/cm³.
• Melting Point: 1400-1450°C.
• Thermal Conductivity: 16.2 W/m·K.
• Coefficient of Thermal Expansion: 17.2 × 10⁻⁶/K.
• Max Service Temperature: 1500°F (815°C) continuous.

Corrosion Resistance

SA 213 TP 304H (equivalent to SA 240 GR 304H) resists mild acids and atmospheric conditions, outperforming SS204 vs SS 304. Higher carbon risks sensitization in welds; anneal for protection. See sa240 gr 316l for chlorides.

Weldability

Fair with ER308H fillers; low heat input (<2.0 kJ/mm) and annealing required. See sa240 gr 321.

Applications

SA 213 TP 304H tube, equivalent to SA 240 GR 304H plate, is used in:

• Boiler and superheater tubes.
• Heat exchanger tubes.
• Power generation piping.
• High-temperature chemical processing lines.
