Carbon steel

Mild and low carbon steel

Mild steel is the most common form of steel as its price is relatively low while it provides material properties that are acceptable for many applications. Low carbon steel contains approximately 0.05–0.15% carbon^[1] and mild steel contains 0.16–0.29%^[1] carbon, therefore it is neither brittle nor ductile. Mild steel has a relatively low tensile strength, but it is cheap and malleable; surface hardness can be increased through carburizing.^[2]

It is often used when large amounts of steel is needed, for example as structural steel. The density of mild steel is 7,861.093 kg/m³ (0.284 lb/in³), the tensile strength is a maximum of 500 MPa (73,000 psi) and the Young's modulus is 210,000 MPa (30,000,000 psi).^{[citation needed]}

Low carbon steels suffer from yield-point runout where the materials has two yield points. The first yield point (or upper yield point) is higher than the second and the yield drops dramatically after the upper yield point. If a low carbon steel is only stressed to some point between the upper and lower yield point then the surface may develop luder bands.^[3]

[edit] Higher carbon steels

Carbon steels which can successfully undergo heat-treatment have a carbon content in the range of 0.30–1.70% by weight. Trace impurities of various other elements can have a significant effect on the quality of the resulting steel. Trace amounts of sulfur in particular make the steel red-short. Low alloy carbon steel, such as A36 grade, contains about 0.05% sulfur and melts around 1426–1538 °C (2600–2800 °F).^[4] Manganese is often added to improve the hardenability of low carbon steels. These additions turn the material into a low alloy steel by some definitions, but AISI's definition of carbon steel allows up to 1.65% manganese by weight.

Medium carbon steel

Approximately 0.30–0.59% carbon content.^[1] Balances ductility and strength and has good wear resistance; used for large parts, forging and automotive components.^[5]

High carbon steel

Approximately 0.6–0.99% carbon content.^[1] Very strong, used for springs and high-strength wires.^[6]

Ultra-high carbon steel

Approximately 1.0–2.0% carbon content.^[1] Steels that can be tempered to great hardness. Used for special purposes like (non-industrial-purpose) knives, axles or punches. Most steels with more than 1.2% carbon content are made using powder metallurgy.

Steel can be heat treated which allows parts to be fabricated in an easily-formable soft state. If enough carbon is present, the alloy can be hardened to increase strength, wear, and impact resistance. Steels are often wrought by cold working methods, which is the shaping of metal through deformation at a low equilibrium or metastable temperature.

五香牛肉

【菜名】五香牛肉 Spicy Roast Beef
【原料】
牛肉一斤，花椒、姜一块，五香桂皮少许，葱一棵红曲米适量、酒糖适量。
【制作过程】
1. 牛肉洗净，漂去血水，用盐码味腌渍；
2. 姜洗净拍松；
3. 葱洗净挽结；
4. 红卤水中加入糖色、五香粉、姜、大葱、牛肉烧沸，然后改用小火卤至牛肉熟软，捞出晾凉，切成薄片，整齐装盘；
5. 牛肉上浇香油和少许卤水即可。
【特点】
该菜色彩红润、牛肉香烂味浓、且回味深长，宜饭宜酒，是佐酒的上佳菜品。
【工艺提示】
牛肉先码味腌渍再卤味更佳；牛肉卤熟后需晾冷切片，切片厚薄要均匀。
【食谱营养】
牛肉(后腿)：牛肉富含丰富蛋白质，氨基酸组成比猪肉更接近人体需要，能提高机体抗病能力，对生长发育及术后，病后调养的人在补充失血、修复组织等方面特别适宜，寒冬食牛肉可暖胃，是该季节的补益佳品；牛肉有补中益气，滋养脾胃，强健筋骨，化痰息风，止渴止涎之功效，适宜于中气下隐、气短体虚、筋骨酸软、贫血久病及面黄目眩之人食用。
【食谱相克】
牛肉(后腿)：牛肉不宜与板栗、田螺、红糖、韭菜、白酒、猪肉同食。

那些与夏天记忆有关的美

纪念老鼠家族

事情发生在2007年夏天

知了在树上唱歌的季节

某日临晨～～一只老鼠反复从我身上跑过～～偶愤怒了～～

第二天就在江西北路买了个老鼠笼子

第一次用西瓜，一晚上没动静～～～

第二次用我嚼过的口香糖，依然没引起他的兴趣～～～

第三次用橘子皮，没反应～～偶又愤怒了～～～

搁手买了乐事薯片和一块吃剩下额鸭下巴～～～

晚上尿尿额时候发觉厨房吱吱的叫～～～开灯看了一下，哇咔咔咔咔～～

偶给他起了个名字，亨利一世～～～下面上PP

微软黑屏对策

1.不要打kb905474补丁，其更新日期为9/23/2008，版本为1.8.0031.9
2.黑屏以后不要慌，
开始-运行-输入REGEDIT回车，在左边栏中找到HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWinlogonNotifyWgaLogon项
将整个WgaLogon项删除即可。以上为经过测试的最简便方法。
