16Mn steel is carbon and manganese steel, carbon content of about 0.16%, yield point is equal to 343MPa (strength level is 343MPa level).
16Mn carbon steel is currently China's most widely used low-alloy steel. 16Mn is a high strength structural steel g
20G seamless steel has a certain temperature and high temperature strength, low carbon content, better plasticity and toughness, Its hot and cold forming and welding performance is good.
Q345D is a commonly used low-alloy sheet in China. The European standard S355J2 and the American ASTM A529MGr50 are equal to Q345D material. Chemical compositions slightly different, the same mechanical properties. "Q" means yield strength, Q345 said th
