Quality Inspection for Alloy Steel Pipe En10216-2 - Seamless Alloy Steel Boiler Pipes Ferritic and Austenitic Superheater alloy pipes Heat Exchanger Tubes – Gold Sanon Detail:
It is mainly used to make high-quality alloy steel pipe for high pressure boiler pipe, heat exchanger pipe and super heat pipe
Grade of high-quality Alloy steel: T2,T12,T11,T22, T91, T92 etc.
|Steel Grade||Chemical Composition%|
|C||Si||Mn||P, S Max||Cr||Mo||Ni Max||V||Al Max||W||B|
For T91 other than above also includes Nickel 0.4, Va 0.18-0.25, Ni 0.06-0.10, Ni 0.03-0.07, Al 0.02, Ti 0.01, Zr 0.01. A Maximum, unless range or minimum is indicated. 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.
|Steel Grade||Mechanical Properties|
|T. S||Y. P||Elongation||Hardness|
|T2||≥ 415MPa||≥ 205MPa||≥ 30%||163HBW(85HRB)|
|T11||≥ 415MPa||≥ 205MPa||≥ 30%||163HBW(85HRB)|
|T12||≥ 415MPa||≥ 220MPa||≥ 30%||163HBW(85HRB)|
|T22||≥ 415MPa||≥ 205MPa||≥ 30%||163HBW(85HRB)|
|T91||≥ 585MPa||≥ 415MPa||≥ 20%||250HBW(25HRB)|
|T92||≥ 620MPa||≥ 440MPa||≥ 20%||250HBW(25HRB)|
In addition to ensuring chemical composition and mechanical properties, hydrostatic tests are performed one by one, and flaring and flattening tests are performed. . In addition, there are certain requirements for the microstructure, grain size, and decarburization layer of the finished steel pipe.
