A269 AISI 305 UNS S30500 1.4303 stainless steel tubes for heat exchanger
AISI 305 UNS S30500 1.4303 stainless steel is comprised of 17% to 19% chromium, 12% carbon, 2% maximum manganese, 10% to 13% nickel with traces of phosphorus sulfur and silicon, with the balance being iron. It was designed for maximum formability, exhibiting good strength and corrosion resistance. Grade 305 has the lowest work and strain hardening rates of all the austenitic stainless steel. This low work hardening rate makes cold working one of the design strengths of 305.

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.
