ASTM A213 TP347/347H Stainless Tubes,Stainless Steel Seamless Tube
A213 TP347 TP347H Stainless Steel Pipe SA213 347H Stainless Steel Tubes
ASTM A213 SA 213 TP347 TP347H EN 10216-5 1.4550 is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperature in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C). Alloy 347 347H is austenitic chromium steel containing columbium stabilized by the addition of columbium and tantalum.

Benefits of 347 347H Stainless Steel
Quality Assurance:
Spezilla's ASME SA213 seamless stainless steel tubes are
produced acc. to the following process and inspection to assure our
quality:
1. Chemical Composition Analysis Test With 100% PMI.
2. Solution Annealing / Bright Annealed.
3. 100% Hydrostatic Test and 100% Eddy Current Test
4. Mechanical Tests includes Tension Test, Flattening Test, Flaring
Test, Hardness Test.
5. Impact Test subject to Standard request.
6. Grain Size Test and Intergranular Corrosion Test.
7. Visual Test and Endoscope Test for Surface Quality Test
Our seamless stainless steel tubes undergo the following tests acc. to specifications:
Flattening Test:
One flattening test shall be made on specimens from each end of one finished tube, not the one used for the flaring test, from each lot.
Flaring Test:
One flaring test shall be made on speci- mens from each end of one finished tube, not the one used for the flattening test, from each lot.
Hydrostatic or Nondestructive Testing:
Each pipe shall be subjected to the nondestructive electric test or the hydrostatic test, the type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.
Markings:
Markings will adhere to prescribed specifications in A999/A999M and shall include the NPS or OD and schedule number or average wall thickness, heat number, and NH (when hydrotesting is not performed) and ET (when eddy-current testing is performed) or UT (when ultrasonic testing is performed). The marking shall also include the manufacturer’s private identifying mark, the marking requirement of section 12.3 on Hydrostatic or Nondestructive Electric Test, if applicable, and whether seamless (SML), welded (WLD), or heavily cold-worked (HCW). For Grades TP304H, TP316H, TP321H & TP347H, the marking shall also include the heat number and heat-treatment lot identification.
