Product Description

Product Introduction of A213 TP347HFG Steel Pipe

1. Product Overview

A213 TP347HFG is an austenitic stainless steel pipe specifically designed for high-temperature and high-pressure environments. It is widely used in power plant boilers, superheaters, reheaters, and petrochemical equipment. This material offers excellent oxidation resistance, creep resistance, and good weldability under elevated temperatures.

Overview

 

Chemical composition (%)
C	Mn	Si	P	S	Cr	Ni
0.06-0.10	≤2.00	≤0.75	≤0.040	≤0.030	17-20.0	9.0-13.00
Note 1: the sum of niobium and tantalum content shall not be less than 8 times of carbon content and not more than 1.0%

Features:

• High chromium and nickel content for enhanced corrosion resistance

• Niobium (Nb) addition improves intergranular corrosion resistance

• Low carbon content reduces sensitization risk during welding
   

Mechanical property Mechanical properties at room temperature
Standard	Tensile properties (longitudinal)			Hardness HRB(HB)
	Yield Strength (MPa)	Tensile strength (MPa)	Elongation(%)
ASME code case 2159	≥205	≥550	≥35	≤90(192)
Note 1: for ASME specimen, the gauge distance is 50mm (for longitudinal bar test with wall thickness less than 8mm, for every 0.8mm reduction, the percentage value that can be reduced from the basic minimum elongation is 1.5%).

High-Temperature Performance:

• Maintains high creep strength at 600~800°C

• Excellent oxidation resistance for long-term high-temperature service
