Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 14995-1994 "high-temperature alloy hot-rolled steel."
Compared with the standard GB/T 14995-1994 The main changes are as follows.
--- Added "normative references", "category" and "order contents" clause;
--- The GB/T 709-2006 standard size allowable deviation inclusion criteria;
--- Increase GH4099 alloy grades and the relevant technical requirements;
--- Specifies the upper limit of residual elements copper;
--- Remove the single electric arc furnace refining, smelting and clearly defined methods of the alloy;
--- Increased plate size measurement method;
--- Clearly defined retest method and determination.
The standard proposed by China Iron and Steel Association.
This standard by the National Steel Standardization Technical Committee (SAC/TC183) centralized.
This standard was drafted. Dongbei Special Steel Group Co., Ltd., Pangang Group Jiangyou Changcheng Special Steel Co., Ltd., metallurgical industry letter
Interest Standards Institute.
The main drafters of this standard. new Chan, Li Aimin, Gu Qiang, Xiawan Yong, wear strong.
This standard replaces the standards previously issued as follows.
GB n179-1982, GB/T 14995-1994.
High-temperature alloy hot-rolled sheet
1 Scope
This standard specifies the size of the superalloy hot-rolled sheet, shape and tolerances, technical requirements, test methods, inspection rules, packaging, marking
Chi and quality certificate.
This standard applies to the manufacture of high temperature load-bearing member with a thickness of 4.00mm ~ 14.00mm high temperature alloy hot rolled sheets (hereinafter
