Description

321/321H Seamless Tube,ASME SA213 ASME SA312 Stainless Steel Tube

321 Stainless Steel Tube 321H Stainless Steel Tube

321 321H stainless steel is basically from 304 stainless steel. They different by a very very small addition of Titanium. The real difference is their carbon content. The higher the carbon content the greater the yield strength. 321 stainless steel has advantages in high temperature environment due to its excellent mechanical properties. Compared with 304 alloy, 321 stainless steel has better ductility and resistance to stress fracture. In addition, 304L can also be used for anti-sensitization and intergranular corrosion.A limitation with 321 is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable. In this case grade 347 is preferred – the niobium performs the same carbide stabilisation task but can be transferred across a welding arc. Grade 347 is therefore the standard consumable for welding 321. Grade 347 is only occasionally used as parent plate material.

Also individual customer specifications.

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.

Available Tube Product Forms:

Straight.


Coiled.

Typical Applications:
