ASME SA 213 UNS N08094 904L Stainless Tubes,904L Stainless Stee Pipes
A213 TP904L Stainless Steel Pipe SA213 904L Stainless Steel TubesASTM A213 ASTM B677 N08904 904L Stainless Steel Tubing is a non-stabilised low carbon(0.02% max) high alloy austenitic stainless steel pipe, there is no carbon deposition in the case of general heat treatment and welding. Eliminates the risk of the corrosion of the crystals that occur after heat treatment and welding.. The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid,Phosphoric Acid, Organic Acid, Inorganic Acid.. It is also highly resistant to chloride attack both pitting / crevice corrosion and stress corrosion cracking.
ASME SA213 904L N08904 Stainless steel tubing is designed for harsh environments of the corrosion conditions. Initially stainless steel is developed for corrosion resistance in sulfuric acid. This feature has been verified that is very successful after many years of practical application. Now, 904L in many countries have been standardized.

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.
Note:
Mill test certificates will be issued according to EN10204.1
All tubes shall be supplied as per applicable ASTM A213 /A213M Specification.
