月度视角： 9 月至今钢铁板块下跌 4.42%，沪深 300 指数上涨 0.38%，钢铁板块跑输沪深 300 指数 4.80 个百分点。 9 月板块涨幅最大的三家为*ST华菱（ 17.15%）、 凌钢股份（ 13.23%）、安阳钢铁（ 12.45%），跌幅最大的三家为马钢股份 （ -13.21%）、方大特钢 （ -11.14%）、鞍钢股份 （ -10.64%）。今年经济走势稳态，商品价格波动更多来自于预期波动造成的库存波动。

需求平稳奠定涨价基调、供给受“地条钢”去化影响弹性不足推波助澜，是今年钢铁行业区别于往年的核心特征，进而造就了行业几乎史无前例的盈利高度与持久度。回归当下，淡季源于限产预期而迅猛上涨，旺季又因 8 月信贷、地产销售等数据低预期引发宏观担忧而凌厉下跌，3 季度钢价反季节性表现无论涨跌都有过度，一轮多空预期之后，4 季度回归正常供需的钢价又将涨跌如何？

展望 9 月份，钢铁行业将进入“金九银十”传统旺季，行业有望呈“供需两旺”的发展态势。目前钢材供需基本呈平衡状态，随着环保等政策情绪被市场消化，后期钢材价格面临一定回调压力。综合来看，行业供需形势继续向好，钢材 PMI 指数有望继续处于扩 张区间，且继续小幅提升的可能性较大。

3D printing is a technique in which a scanned or digitally designed object is formed into a three-dimensional solid using an additive process. In this process, metal is applied in successive layers with very less wastage. 3D printing products are built from materials that are alternatives to conventional plastic and metals. The global metal-based 3D printing market will grow at a rapid rate during the forecast period.The growth is attributable to the emerging demand from the aerospace and healthcare industry.3D printing metals help in achieving complex geometries, extreme requirements,and weight reduction for the aerospace industry. Fuel nozzles and guide vanes arebeing produced using the technique.

Metals form an important component of many manufacturing and end-user industries.Industries such as the automotive, aerospace,machinery, and consumer appliances use metals such as steel, aluminum, and cast iron as basic components. The process of applying pressure on sheet metal to obtain the desired industry product is known as metal stamping. Metal stamping can be either carried out by punching or pressing the metal sheet. Metal stamping involves different processes. 

Cast iron is an alloy of iron and carbon; it is hard, brittle, and non-malleable. The concentration of carbon varies from 2% to 5%. The alloy has lower melting temperature and requires less refining when compared with steel, which has a typical carbon content of 0.5%.The various types of iron alloys widely used for casting include gray iron, ductile iron, and malleable iron.
