What's the material of Q325 steel pipe?
Q235 refers to the material yield stress of 235MPa carbon steel, because of its low price, good machining and welding performance, it is generally used for welding structural parts. Of course, the unimportant parts can be used for it.
In terms of deoxidation methods, F, B, Z can be expressed as boiling steel, flat killed steel, killed steel and boiling steel. They are deoxidized steel, which is of poor plasticity and toughness. Welded joints made of this material are susceptible to cracks when subjected to dynamic loads. Should not work at low temperatures, sometimes hardening. In contrast, calming steel is excellent and uniform, with good plasticity and toughness.
Plain carbon structural steelIt's a kind of steel material. Q stands for the yield of this material, and the latter 325 means the yield value of this material, at around 325. And the yield value will decrease as the thickness of the material increases.
