钢材

The metallographic change and the distribution of alloy elements after the tube has run in the high temperature condition for longtime is more believable and franker to evaluate the tubes remain life time.

然后，通过试验研究了过热器和再热器管12Cr2MoWVTiB钢材的金相组织、合金元素对管道寿命的影响，分析了管材在高温长期运行后金相组织和合金元素分布的变化情况，对管材寿命进行定性评估。

Material of grounding device is reinforced galvanization steel.

接地装置的材质为加强型镀锌钢材。

On the appropriate treatment of galvanized steel and alloy has excellent adhesion

在适当处理的镀锌钢材及铝合金上具有优良的附着力

So the technology of hot dip galvanizing should be adjusted with the different composition of steel.

故对不同成分的钢材应采用不同的热镀锌工艺。

Electromagnetic nondestructive testing on the quality of steel has been studied for many years and acquired a great deal of achievement. However there are many problems in the testing of hardness and cracks, and mess problem of work pieces. For example the traditional nondestructive testing is difficult for the hardness gearwheel roughcast, and the traditional artificial test means is comparative slowly.

用无损检测方法进行钢铁材质检测的研究工作取得了大量成果，然而对于钢材及其制品的混料、硬度和裂纹质量检测还存在许多难题，如用传统检测方法检测齿轮毛坯的硬度效果不够理想，而且人工记录方法较慢。

Such a revolution has happened before, in steel: giantism once seemed insuperable, yet today plenty of steel is made in "mini-mills", which use scrap as raw material.

这样的革命曾经在钢铁行业发生过：巨无霸型企业看似不可战胜的，然而今天很多的钢材由使用废铁作为原材料的"小钢铁厂"制造。

Iron and steel and car are the industry of 6 big pillar of Shanghai, rolled steel price fall and car sales volume drop, to Bao Gang the group is mixed on steam group impact is especially big, and the grasper that makes international shipping center as Shanghai -- foreign hill harbor, marine price fall is an influence more tremendous, because the heavy disaster area of this banking crisis is the United States, the line with foreign hill main harbor is North America and Europe.

钢铁和汽车是上海的六大支柱产业之二，钢材价格下降和汽车销量下降，对宝钢集团和上汽集团影响尤大，而作为上海打造国际航运中心的抓手——洋山港，海运价格下降更是影响巨大，由于此次金融危机的重灾区是美国，洋山港主要的航线就是北美和欧洲。

Continuous Operated Air Grease Gun is a specially designed, high-quality and professional air tool, made of the best materials and ideal for lubricating maintenance for transportation implements, agricultural machinery and industrial equipment etc.

由优质钢材锻造，是润滑保养各种机械的理想工具。

Has more than 800 square meters of factory buildings and more than 1,000 square meters of steel piling up space, the installation of a large milling machines, grinders and other machinery and equipment.

拥有800多平方米的厂房和1000多平方米的钢材堆放场地，添置有大型的铣床、磨床等机械设备。

Hot Rolled Half-round Steel and Half-oval Steel, Dimensions, Weights, Permissible Variations

棒钢材。热轧半圆钢和半椭圆钢。尺寸。重量。允许偏差

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
