The results show that 82B wire rod brittle fracture is mainly caused by excessive inclusion,reticulate carbide,lower sorbite in the microstructure,and surface defect of wire rod.

结果表明，82B钢盘条脆断的主要原因是夹杂物级别超标、组织中出现网状碳化物、索氏体含量偏低以及盘条表面缺陷等。

As per our recent discussion I am seeking a reliable sheet metal / press shop in China to manufacture baking pans to suit our specifications. To be made from 0.6mm aluminium coated steel, approximate dimensions 300mm long x 100mm wide x 100mm deep, with a wire reinforced top edge. The manufacturing process requires multiple press operation, roll forming metal banding, spot welding and non stick silicone coating.

根据我们最近的商议，我想在中国找一家可靠的金属商店，帮我们定做平底锅，平底锅的规格如下：0.6毫米厚的渡钢铝，长宽高的尺寸大概为：300mm*100mm*100mm，用一条金属条加固在顶端，加工程序需要多次压制，外围钢条需要焊接而非用胶水粘贴。

Iron dragon each composed of two long, and each separately by the leading long, long tail and representative body of the 14 long balls, each 24 long balls by the steel composition, 28 long balls from 28 individual performances, commonly known as二十八宿, should be on the number of days, reprovision has Longzhu, Longmen, cloud film虾兵蟹将, lighting fireworks, dance closely together, can be combined, flexible, convenient and endless changes.

Through a series of quenching, tempering, tensile testing, low-temperature impact test and metallographic analysis, we ultimately came to the following conclusions:(1) low-carbon alloyed steel 20CrMn2NiMoV quenching at 870℃ and tempering at 200℃, whose structure contains tempered dislocation lath martensite and few small bainite under mixed, has the best obdurability;(2) Carbon Steel 45CrMn2NiMoV quenching at 850℃ and tempering at 620℃, whose structure is sorbitic, has a performance less than that of low-carbon Alloyed steel, but it can also meet the basic design requirements.(3) Mn can substitute for the role of Ni within limited extent.

通过一系列淬火、回火、拉伸试验、低温冲击试验以及金相分析，最终得出以下主要结论：（1）低碳合金钢20CrMn2NiMoV经870℃淬火+200℃回火，得到回火位错型板条马氏体+少量细小下贝氏体的混合组织，具有最佳的强韧性配合；（2）中碳合金钢45CrMn2NiMoV经850℃淬火+620℃回火，得到回火索氏体组织，综合性能虽然不及低碳合金钢，但也能基本满足设计要求；（3）Mn在一定程度上能够替代Ni的作用，适量的Mn和Ni相互配合可以得到最佳的低温韧性，因此&以Mn代Ni&是低温钢材料研究开发中一条可行的适合我国资源状况的合金化思路。

We use two ways to build roof system. To assemble on site light steel purline. To hoist and assemble prefabricated wall body and roof. In the first method, we can build roof with complicated styles and with flexible layout. By the second one, we can build faster.
