SA213 SA312 TP304H Tubing 19.05x2.11mm,Stainless Steel Seamless Tube
304H stainless steel is a variation of the 18% chromium – 8% nickel austenitic Alloy 304, in which the carbon content is controlled to a range of 0.04% – 0.1% (ASME SA213) to provide improved high temperature strength to parts exposed to temperatures above 1500°F (815°C).
Unlike 304L, Type 304H has a higher carbon content making the steel more suitable for use in applications where elevated temperatures are present. It is an austenitic chromium-nickel steel alloy and the greater carbon content delivers an increased tensile strength and yield strength. The material is recommended for use in ASME pressure vessel in working service above 815 °C due to the grades heat resistant properties.

Typical Manufacturing Specifications:
Also individual customer specifications.
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:
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.
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 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.
Mill test certificates will be issued according to EN10204.1
All tubes shall be supplied as per applicable ASTM A213 /A213M Specification.
