Embodiment 1

[0014] 1. Composition design: iron is the matrix component, the alloy element composition and its content are shown in Table 1, and the content of other impurity elements is less than 0.005wt%.

[0015] 2. Preparation method:

[0016] (1) Design the ingredients according to the composition in Table 1, smelt in a 500kg intermediate frequency induction furnace, use induction magnetic stirring to ensure the uniformity of the molten steel composition, and use pure aluminum as the deoxidizer; use a 180mm ingot metal mold and cast molding;

[0017] (2) The steel ingot is forged at 1200℃±50℃ for 3 hours and then forged into a square billet of 80mm×80mm×2000mm, and air-cooled; then the main elements are segregated and the range method is used to determine the result; Keep it at ℃±50℃ for 1 hour, hot-rolled into a round bar of Φ45mm×2500mm;

[0018] (3) Number the rolled round bars, remove the scale, and flatten them into a Φ40mm×40mm spectrum block.

[0019] 3. The uniformity inspection of sta...

Abstract

The invention discloses a standard sample for spectral analysis of free cutting steel SAE1215, belonging to the technical field of new materials and metallurgical analysis. Specification of the standard sample is a cylinder of phi 40 mm * 40 mm, the standard sample comprises iron which is matrix ingredient, alloy elements consisting of 0.06-0.07% of C by weight, 0.01-0.02% of Si by weight, 1.25-1.35% of Mn by weight, 0.05-0.06% of P by weight, 0.35-0.40% of S by weight, 0.02-0.04% of Cr by weight, 0.005-0.01% of Ni by weight and 0.005-0.02% of Cu by weight, and less than 0.05 of the other impurity elements by weight. The standard sample is featured with good uniformity, accurate measurement value, good stability and convenience, and is capable of meeting demands on calibration and test for spectrometer, so that the standard sample is a better material standard for measuring free cutting steel SAE1215.

Description

Technical field [0001] The invention relates to a standard sample for free-cutting steel SAE1215 spectrum analysis, which belongs to the technical field of new materials and metallurgical analysis. Background technique [0002] SAE1215 is a kind of free-cutting steel. Compared with other free-cutting steels, it does not contain lead and is an environmentally friendly material. During smelting, adding an appropriate amount of phosphorus and high content of sulfur to the steel will increase the hardness and strength of the steel, reduce the toughness, and make the chips easy to break and remove, thereby obtaining good machinability. Mainly used to make export machinery and equipment: woodworking machinery, ceramic machinery, food machinery, construction machinery, etc.; electrical product parts; furniture; metal appliances, etc. With economic development and environmental protection requirements, the application of this steel grade is becoming more and more extensive. Due to the ...
