硬さ換算表（HVベース）Steel Hardness Conversion Table

硬さ換算表。ロックウェルからの換算は前の投稿を参考に。

HR**はロックウェル硬さ（HRA, HRB, HRC, HRD, HR15N, HR30N, HR45N）
HVはビッカース硬さ
HBはブリネル硬さ(10mmの球で3000kgfで押すとHB 10/3000)、硬球で押すのであまりにも硬い材料だと鋼球も潰れて値がおかしくなる。
HBWはタングステンカーバイドの球で押す場合。
HSはショア硬さ。
Tensile Strengthは引張強度。おおよそビッカース硬さの3.3倍程度の値になる。

換算についてはJavaScriptで作ったHTMLファイルので、こちらのほうが使い勝手はいいでしょうか。
