彈簧鋼板主要是有好的彈性、又由于它是在動載荷環境條件下工作的、所以對制造彈簧的材質 主要的應有高的屈服強度;在承受重載荷時不引起塑性變形;應有高的疲勞強度、在載荷反復作用下具有長的使用壽命,并有足夠的韌性和塑性、以防在沖擊力作用下突然脆斷。
  彈簧鋼板是指由于在淬火和回火狀態下的彈性、而專門用于制造彈簧和彈性元件的鋼。鋼的彈性取決于其彈性變形的能力、即在規定的范圍之內、彈性變形的能力使其承受一定的載荷、在載荷去除之后不出現 變形。
彈簧鋼板應具有優良的綜合性能、如力學性能(特別是彈性極限、強度極限、屈強比)、抗彈減性能(即抗彈性減退性能、又稱抗松弛性能)、疲勞性能、淬透性、物理化學性能(耐熱、耐低溫、抗氧化、耐腐蝕等)。
