25.4x2.11 309S Stainless Steel Pipe TP309S 309H Stainless Steel Tube
ASTM A213 ASME SA 213 309S Stainless Steel Tube, EN 10216-5 1.4833 Stainless Steel Tubing is typically used for elevated temperature applications. Its high chromium and nickel content provides comparable corrosion resistance, superior resistance to oixidation, and the retention of a larger fraction of room temperature strength than the common austenitic Alloy 304.
309S stainless steel pipe is used often for higher temperature applications. While its oxidation resistance surpasses that of alloy 310, its resistance to corrosion is equivalent to that of alloy 310. Alloy 309 is highly weldable and cold formable, although it does require stronger forming machines and continuously increasing pressure. Typical machining methods are used for stainless steel grade 309, but it is tougher and does tend to harden more quickly. Like 310 Stainless Steel, 309S Stainless Steel has a high chromium and nickel content which grants excellent resistance to aqueous corrosion.

Quality Assurance:
Spezilla's ASME SA213 TP304 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.
