Overview

Application

It is mainly used to make high-quality alloy steel pipe for high pressure boiler pipe, heat exchanger pipe and super heat pipe

Main Grade

Grade of high-quality Alloy steel: T2,T12,T11,T22, T91, T92 etc.

Chemical Component

Steel Grade Chemical Composition%

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.
