Effect of folding performance
(1) carbon;The higher the carbon content, the higher the hardness of the steel, but the worse its plasticity and toughness.
(2) sulfur;Is the harmful sundries in steel, high sulfur steel in high temperature pressure processing, easy to brittle, usually called hot brittleness.
(3) phosphorus;This phenomenon is called cold brittleness. In high-quality steel, sulfur and phosphorus should be strictly controlled. But on the other hand, low carbon steel contains high sulfur and phosphorus, which can make it easy to cut off, is beneficial to improve the cutting ability of steel.
