Q235F steel consists of Q+number+quality grade symbol+deoxygenation method symbol. Its steel number is prefixed with "Q", which represents the yield point of the steel, and the following number represents the yield point value in MPa. For example, Q235 […]

Q235 has five grades: A, B, C, D, and E. A is 40 degrees above zero, B is 20 degrees above zero, C is above zero, D is 20 degrees below zero, and E is 40 degrees below zero.
This performance is required in colder regions. […]

Q215A is a kind of steel material. Q represents the yield degree of this material, and the latter 215 means that the yield strength is 215MPa, and the yield value will decrease as the thickness of the material increases. Due to the moderate carbon content […]

Q195 steel is a carbon structural steel. Yield strength 195MPA. Lower intensity than Q235. […]

Seamless steel pipe is a relatively common type of pipe, so what are the materials of seamless steel pipe? […]
