合金钢板检材料的进场验收,复验按批进行,标志应粘贴牢固、字迹清晰,包装材料应符合有关法律规定,每批交货的钢板必须有质量保证文件和力学性能试验报告。

Alloy steel materials approach acceptance, re inspection according to the batch, logo should be pasted firmly, clear handwriting, packaging materials should comply with the relevant laws and regulations, must have quality assurance and mechanical performance test report file delivery of each batch of steel plate.

尤其是汽车用合金钢板在动态条件下的拉伸性能检测变得越来越重要。然而,不同检测实验室采用的检测方法不同,没有可利用的检验标准,并且生成的数据通常不具有可比性。为了提高钢在高速拉伸试验条件下的数据质量,12Cr1MOV合金钢板提高碰撞模拟的准确性。

Especially the tensile performance testing of automotive alloy steel plate under dynamic conditions becomes more and more important. However, the detection methods used by different testing laboratories are different, there are no available inspection standards, and the generated data are usually not comparable. In order to improve the data quality of steel under high tensile test conditions, 12Cr1MOV alloy steel plate was used to improve the accuracy of collision simulation.

从适用范围、设备器材、检测条件和方法、对比试块、灵敏度的调校、缺陷的测定与评定等几方面对国内外常用钢板超声检测标准进行对比分析,为有关单位和检验人员更加深入地理解和使用标准,正确执行标准提供参考。

Analyzed from the scope, equipment, test conditions and methods, contrast test block, adjust the sensitivity of defect testing and evaluation of several aspects of commonly used at home and abroad steel plate ultrasonic testing standards for personnel and inspection of the relevant units of more in-depth understanding and use of standard, the correct reference standard.

其中对各等级的文字描述为:

The text of each grade is described as:

A级:全面地覆盖着氧化皮,允许有微量锈斑(直径不大于10mm)的钢材表面;

Class A: fully covered with oxide, allow trace rust (diameter less than 10mm) of the steel surface;

B级:已发生锈蚀并且部分氧化皮已经剥落的钢材表面,剥落面积不超过总氧化表面积的1/10;

Grade B: steel surface that has corroded and partially oxidized the peel has peeled off the area of not more than the total oxidation surface area of 1/10;

C级:氧化皮已因锈蚀而剥落,或者可以刮除,并且有少量点蚀的钢材表面;

Grade C: the surface of the oxide has been peeled off due to rust, or can be scraped, and a small amount of pitting steel surface;

D级:氧化皮已因锈蚀而全面剥落,并且已普遍发生点蚀的钢材表面。n

Grade D: oxide skin has been completely peeled off due to rust, and has generally pitting steel surface. N

相信看了本文的介绍后,对济钢代理商的这方面也会有自己的一番认识,以后针对http://www.jnyygt.com必须要严格等问题也能很好的解决。

Believe that the introduction of this article, will also have a new understanding of the Jinan agents, later for http://www.jnyygt.com must be strict and other issues also can be a good solution.
