Specification

ASTM A213 ASME SA213 TP347HFG Seamless Steel Tubes

1 Introduction
TP347HFG is a chromium nickel niobium austenitic stainless steel with the same composition as TP347H, but with different processing technology.

 

2.Application
Like TP347H, ASME SA213 TP347HFG steel tubes are mainly used to manufacture high temperature superheater, high temperature reheater, high temperature section of platen superheater and various high temperature and high pressure resistant pipe fittings of large-scale power generation boiler with supercritical pressure parameters. However, for pressure bearing parts, the maximum working temperature should be higher. Because its comprehensive performance is much better than TP347H, it should be widely used in the future Use.

 

3.Heat treatment
The supply state of TP347HFG steel tubes are solution treatment. Three processes are required: first, initial solution treatment
(the solution treatment temperature is 50 ºC higher than the final solution treatment temperature); second, cold processing; third,
final solution treatment at a temperature not lower than 1180 ºC.

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%

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%).
