08F中F表示是沸騰鋼，08表示為含碳量為萬分之八。08F鋼強(qiáng)度、硬度很低，而塑性、韌性極高，具有良好的冷變形性和焊接性，正火后切削加工性

尚可，退火后導(dǎo)磁率較高，剩磁較少，但淬透性、淬硬性極低。故冷加工時(shí)，應(yīng)采用消除應(yīng)力熱處理，或水韌處理，防止冷加工斷裂。08F鋼的塑性

很好，主要用來制造冷沖壓件。錳的在鋼中起到增加彈性強(qiáng)度的作用，因此在符合要求的情況下，含量可以有偏差。

In 08F, f indicates boiling steel, and 08 indicates that the carbon content is 8 / 10000. 08F steel has low strength and hardness, high plasticity and toughness,

good cold deformation and weldability, acceptable machinability after normalizing, high permeability and less residual magnetism after annealing,

but extremely low hardenability and hardenability. Therefore, during cold working, stress relief heat treatment or water toughening treatment shall be

adopted to prevent cold working fracture. 08F steel has good plasticity and is mainly used to make cold stamping parts. Manganese plays a role in increasing

elastic strength in steel, so the content can be deviated when it meets the requirements.
