Description

Ａｌ：０.３質量％以下
必要に応じて添加される合金成分であり、製鋼時に脱酸材として添加される。しかし、Ａｌの過剰添加は非金属介在物の増加を招き、靭性低下，表面欠陥の原因となるため、Ａｌ含有量の上限を０.３質量％に設定する。
Ｂ：０.０１００質量％以下
必要に応じて添加される合金成分であり、Ｎを固定し、耐食性，加工性を改善する作用を呈する。Ｂの添加効果は、Ｂ含有量０.００１０質量％以上でみられる。しかし、０.０１００質量％を超える過剰量のＢを過剰に添加すると、熱間加工性，溶接性が低下する。
以上に挙げた成分以外にＣａ，Ｍｇ，Ｃｏ，REM等が溶製中に原料であるスクラップから混入することもある。これらの成分は、格別多量に含まれる場合を除き、絞り加工時の真円度やプレス加工後の寸法精度に悪影響を及ぼさない。 Al: not more than 0.3% by mass is an alloy component added as needed, and is added as a deoxidizing agent during steelmaking. However, excessive addition of Al causes an increase in nonmetallic inclusions, which causes a decrease in toughness and surface defects. Therefore, the upper limit of the Al content is set to 0.3% by mass.
B: 0.0100% by mass or less An alloy component added as necessary, and has an effect of fixing N and improving corrosion resistance and workability. The effect of adding B is observed when the B content is 0.0010% by mass or more. However, when an excessive amount of B exceeding 0.0100% by mass is excessively added, hot workability and weldability are reduced.
In addition to the above-mentioned components, Ca, Mg, Co, REM, and the like may be mixed from scrap as a raw material during melting. These components do not adversely affect the roundness at the time of drawing and the dimensional accuracy after pressing, unless they are contained in a particularly large amount.
