这个段子好玩。
不过冷钢也挺2的,3V这种碳那么少的,也写个HIGH CARBON....忽悠外行么
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.[9][10]
High-carbon steel
Approximately 0.6–0.99% carbon content.[1] Very strong, used for springs and high-strength wires.[11]
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. Note that steel with a carbon content above 2.0% is considered cast iron.
含碳量0.3-0.59% 被称为中碳钢
含碳量0.6%-0.99% 被称为高碳钢
含碳量1%-2.0% 被称为超高碳钢
CPM3V含碳量 0.8%,被称为High Carbon Steel倒是没啥问题。 |
