Phosphorus (P)

Phosphorus in steel solid solution strengthening and cold hardening effect is strong, as an alloy elements to low steel/" target="_blank" class="keylink">alloy steels, can improve the strength and the steel atmospheric corrosion resisting performance, but reduce its cold stamping performance. Phosphorus and sulfur and manganese joint use, can increase the steel is cutting performance, increase the surface of the product quality, used for easy cutting steel, so easy to cut steel phosphorus is higher also. Phosphorus soluble in ferrite, although can improve the strength and hardness of the steel, the largest of the serious harm is segregation, increase the brittleness, significantly reduce steel plasticity and toughness, cause easily when cold steel in crisp crack, also called "ductile-brittle" phenomenon. Phosphorus on welding sex also have adverse effects. P is harmful element, should be kept under strict control, general content is not more than 0.030%-0.040%.
