20# steel 8--150mm steel plate cut 20# steel tensile yield strength

20# is excellent carbon steel, GB/T711 standard. The 20 of 20# steel refers to the carbon content, and the carbon content is 0.2%, which is low carbon steel. Steel can be divided into low carbon steel, medium carbon steel and high carbon steel. Low carbon steel - carbon content is generally less than 0.25%; Medium carbon steel - carbon content is generally between 0.25 and 0.60%; High carbon steel - carbon content is generally greater than 0.60%.
