The original 1K103, 1K104 and 1K105 merged into the cost standard 1K105; adjusted and improved the chemical or classification of the grades: changed "basic ingredients and characteristics" to "performance characteristics" + and supplemented the corresponding Content (see Table 1) - Appendix A is cancelled.
This standard replaces GB/T15019-1994 from the date of implementation. This standard is proposed by the China Iron and Steel Association. This standard is under the jurisdiction of the Metallurgical Industry Information Standards Research Institute. Drafting units of this standard: Metallurgical Industry Information Standards Research Institute, Iron and Steel Research Institute. The ten main authors of this standard: Peng Sanhui, Chen Wenzhi, Wu Qiansi, Dai Qiang, Luan Yan. This standard was first issued in 1989 as GBn292-1989. In 1994, it was adjusted to GB/T15019-1994. T

GB/F 15019—2003
This standard specifies the classification and designation of quenching metals, the naming, and the designations, chemical composition, performance characteristics and main uses of various alloys.
This standard applies to the classification of quenching metals and the designation of various designations. 2 Terms and Definitions
The following terms and definitions apply to this standard. 2.1
Quickly queached metal is a metal with amorphous, nano-crystalline or microcrystalline structure obtained by rapid condensation of liquid metal. 2.2
Amorphous metal
A metal frozen from the atomic configuration of liquid metal, whose structure is long-range disorder and short-range order. 2.3
Nanecrystallized metal is a metal with amorphous, nano-crystalline or microcrystalline structure obtained by rapid condensation of liquid metal. melal

3 Classification
Fast metals are divided into the following categories according to their basic properties:
a) fast quenching soft magnetic alloys (abbreviated as \fast soft magnetic\); b) fast hydromagnetic alloys (abbreviated as \fast hydromagnetic alloys) d) fast quenching expansion alloys (abbreviated as \fast expansion\): e
fast thermal bimetals (abbreviated as \fast bimetals): fast precision resistance alloys (abbreviated as \fast electric positive\); f
fast welding alloys (abbreviated as \fast welding welding"): fast corrosion resistant heat resistant alloys (abbreviated as \fast corrosion resistant heat resistant alloys) h
The physical composition of the quick-quenching alloy is classified into the following order: 3.2
Quick-quenching iron-based alloy (Fe65%):

h) Quick-quenching titanium-zirconium-based alloy (Ti1Zr≥65%). Note: The number of elements in brackets contains the number of atoms: 4. Grade representation method
Quick-quenching metal grades are represented by a combination of Chinese phonetic letters and Arabic mathematics. 4.1
The standard form of fast-quenching metal grades is:
The Chinese phonetic alphabetic symbol indicating a certain characteristic of the fast-quenching metal; the numerical sequence of grades with different characteristics within the same fast-quenching metal category
The numerical sequence of the matrix component of the fast-quenching metal; the Chinese phonetic alphabetic symbol indicating the fast-quenching metal; the numerical code indicating the basic characteristic category of the fast-quenching metal 4.2 The letter "K" in the grade (the first letter of the Chinese phonetic alphabet of "fast" (capitalized) indicates "fast-quenching metal". 4.3 The number before the letter "K" indicates the category of the basic characteristic of the fast-quenching metal, such as: fast-quenching alloy;

4.5' The first and second digits after the letter "K\ represent the serial number of the brand within the same metal category, starting from 01 and going to 994.6. Generally, no letter symbols are added. According to special needs, letters indicating certain characteristics of the metal, production process, etc. can be added to the end of the brand, such as:
Add "" to indicate that the metal has a short hysteresis loop characteristic. Add "H" to indicate that the metal has a high magnetic conductivity. 5 Brand naming
GB/T15019—2003
5.1 Brands in the scientific research and trial production stages can be represented by scientific research and trial production codes, enterprise codes, or foreign codes before they are formally unified.
5.2 All metals that have been scientifically researched, trial-produced, and identified by the relevant organization and transferred to mass production should be reported by the main production unit to the standardization office for approval in accordance with the provisions of this standard. Unified naming rules. 5.3 When compiling national standards for metal products, the product grade notation method specified in this standard should be adopted. 6 Metal grades and their chemical composition, performance characteristics 6.1 The grades of metals and their chemical composition, performance characteristics, and main uses are shown in Table 1. The chemical composition of each grade specified in this standard is only used to represent the usual chemical composition range of the alloy grade. Adjustment of the composition range is allowed in product standards or contracts. cbzxz.net
