Where ellipses (…) appear in this table, there is no requirement, and analysis for the element need not be determined or reported. B It is permissible to order T2 and T12 with a sulfur content of 0.045 max. C Alternatively, in lieu of this ratio minimum, the material shall have a minimum hardness of 275 HV in the hardened condition, defined as after austenitizing and cooling to room temperature but prior to tempering. Hardness testing shall be performed at mid-thickness of the product. Hardness test frequency shall be two samples of product per heat treatment lot and the hardness testing results shall be reported on the material test report.

Test Requirement
Hydraustatic Test:
The Steel Pipe Should Be Tested Hydraulically One By One. The Maximum Test Pressure Is 20 MPa. Under The Test Pressure, The Stabilization Time Should Be Not Less Than 10 S, And The Steel Pipe Should Not Leak. Or The Hydraulic Test Can Be Replaced By Eddy Current Testing Or Magnetic Flux Leakage Testing.
Nondestructive Test：
Pipes That Require More Inspection Should Be Ultrasonically Inspected One By One. After The Negotiation Requires The Consent Of The Party And Is Specified In The Contract, Other Non-Destructive Testing Can Be Added.
Flattening Test：
Tubes With An Outer Diameter Greater Than 22 Mm Shall Be Subjected To A Flattening Test. No Visible Delamination, White Spots, Or Impurities Should Occur During The Entire Experiment.
Hardness Test:
For Pipe Of Grades P91, P92, P122, And P911, Brinell, Vickers, Or Rockwell Hardness Tests Shall Be Made On A Specimen From Each Lot
