The advantages of HSS steel are hard, strong cutting ability, strong opening performance, and good maintainability; The disadvantages are slightly poor toughness and abrasiveness, low rust resistance, and frequent oil protection when not in use; When the temperature is higher than 500 degrees, the red hardness begins to decline, and when the temperature is higher than 700 degrees, the annealing begins.
