ASTM 213 Tp310s/316/304 Weld Stainless Steel Pipe Product Analysis

1. Standards

Standard

Details

ASTM 213

This standard is designed for seamless ferritic and austenitic alloy - steel boiler, superheater, and heat - exchanger tubes. For welded Tp310s/316/304 pipes, it ensures compliance in manufacturing processes, dimensional tolerances, and mechanical properties. During production, the welding process must meet specific quality requirements to guarantee the integrity of the pipes. Dimensional tolerances for diameter and wall thickness are strictly controlled to ensure proper fit and performance in various applications.

Tp304	≤0.08	≤1.00	≤2.00	≤0.045	≤0.030	18.0 - 20.0	8.0 - 10.5	-	-

3. Mechanical Properties

Grade	Tensile Strength (MPa)	Yield Strength (MPa)	Elongation (%)
Tp310s	≥515	≥205	≥35
Tp316	≥515	≥205	≥35
Tp304	≥515	≥205	≥40

4. Application Fields

Grade	Applications
Tp310s	- High - temperature applications such as furnace components, kilns, and incinerators. Its excellent high - temperature strength and oxidation resistance make it suitable for withstanding extreme heat. - Aerospace applications where components are exposed to high - temperature environments.
Tp316	- Chemical industry, especially in environments with chloride - containing substances. It offers outstanding corrosion resistance, which is crucial for handling aggressive chemicals. - Food and pharmaceutical industries due to its hygienic properties and ease of cleaning. - Marine applications as it resists seawater corrosion effectively.
Tp304	- General - purpose applications in construction, architecture, and household appliances. It provides good corrosion resistance at a relatively lower cost. - Heat exchangers in HVAC systems. - Dairy and beverage processing equipment.

5. Welding Considerations

Welding Techniques

For Tp310s/316/304 pipes, common welding techniques such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and shielded metal arc welding (SMAW) can be used. However, for Tp310s, special attention should be paid to the high - temperature properties during welding to avoid compromising its performance. Tp316 and Tp304 are relatively easier to weld, but proper welding parameters still need to be selected to ensure good weld quality.

Welding Materials

The choice of welding materials depends on the grade of the pipe. For Tp310s, filler metals with a similar high - chromium and high - nickel composition are recommended. For Tp316, ER316 - type filler metals are commonly used, and for Tp304, ER308 - type filler metals are suitable. Using the correct welding materials helps to maintain the mechanical and corrosion - resistant properties of the base material in the welded joint.

Post - Weld Heat Treatment

In some cases, post - weld heat treatment may be necessary. For Tp310s, heat treatment can help relieve residual stresses and improve the high - temperature performance. For Tp316 and Tp304, heat treatment may be required to enhance corrosion resistance, especially in applications where the welded pipes are exposed to aggressive environments. The heat treatment process should be carefully controlled to avoid any negative effects on the material properties.

6. Advantages and Disadvantages

Grade	Advantages	Disadvantages
Tp310s	- Exceptional high - temperature strength and oxidation resistance. - Good resistance to carburization in high - temperature environments.	- Higher cost compared to Tp316 and Tp304 due to the high content of alloying elements. - Machining can be more difficult because of its alloy composition.
Tp316	- Superior corrosion resistance, especially against chloride - induced corrosion. - Good formability and weldability, facilitating fabrication. - High strength - to - weight ratio.	- More expensive than some standard carbon steel pipes. - Susceptible to stress corrosion cracking in certain aggressive environments if not properly designed.
Tp304	- Widely available and relatively cost - effective among stainless - steel grades. - Good corrosion resistance for general - purpose applications. - High ductility, allowing for easy forming.	- Lower corrosion resistance compared to Tp316, especially in harsh chemical environments. - Less suitable for high - temperature applications compared to Tp310s.
