Embodiment Construction

[0034] In order to enable those skilled in the art to which the application belongs to understand the application more clearly, the following in conjunction with the appended Figure 1-2 , the technical solution of the present application will be described in detail through specific embodiments.

[0035] The invention provides a 980MPa level anti-riot steel plate for ATM machines, the chemical composition of which is calculated by mass percentage: C: 0.10-0.15%; Si: 0.2-0.6%; Mn: 1.10-2.0%; Al: 0.01-0.06% ; P≤0.015%; S≤0.004%; N≤0.004%; Cr: 1.0~1.5%; Ti+Nb≤0.2%;

[0036] Control the carbon equivalent CE≤0.65, the carbon equivalent CE is an important parameter to judge the welding performance, if the carbon equivalent CE value is greater than 0.65, the welding performance will decline significantly, CE=[C+Mn / 6+(Cr+Mo+V) / 5+ (Ni+Cu) / 15]*100%.

[0037] In practical application, depending on the type of steel, it has different composition content. Please refer to Table 1 below, whi...

Abstract

The invention discloses a 980 MPa grade ATM machine anti-riot steel plate and a fabrication method for the 980 MPa grade ATM machine anti-riot steel plate and belongs to the technical field of metal material preparation. The 980 MPa grade ATM machine anti-riot steel plate comprises the chemical ingredients of, in percentage by mass, 0.10-0.15% of C, 0.2-0.6% of Si, 1.10-2.0% of Mn, 0.01-0.06% of Al, less than or equal to 0.015% of P, less than or equal to 0.004% of S, less than or equal to 0.004% of N, 1.0-1.5% of Cr, less than or equal to 0.2% of Ti+Nb, 0.0015-0.0020% of B and the balance Feand unavoidable impurities. According to the steel plates obtained by the 980 MPa grade ATM machine anti-riot steel plate and the fabrication method for the 980 MPa grade ATM machine anti-riot steel plate, the yield strength reaches the 800 MPa grade, the tensile strength reaches 980 MPa or above, the ductility A reaches 13% or above, meanwhile, the obtained steel plates have good cold bending andwelding performance, and the alloy and process costs are both low.

Description

technical field [0001] The invention relates to the technical field of metal material preparation, in particular to a 980MPa level anti-riot steel plate for ATM machines and a manufacturing method thereof. Background technique [0002] There is no proprietary grade of steel for ATM machines in China. Currently, 700MPa steel grades with good cold forming performance are mainly used in the manufacture of ATM machines. The product specification is 12.5mm, mainly precipitation-strengthened steel plates. The S500MC-S700MC series in the European standard En10149, the DOMEX series of the Swedish SSAB Steel Plate Co., Ltd., and the domestic Baosteel BS550-BS700MC series. With the development of the safe and ATM machine industry, in order to improve the impact resistance of iron cabinets, prolong the anti-flame cutting time, and meet the safety requirements such as fire protection and prying resistance, insurance products are produced with hot-rolled low-alloy high-strength and ultra...
