Angle Iron Product Description
Q195 yog cov khoom siv carbon steel nrog lub zog tawm los ntawm 195MPA. Nws muaj plasticity siab, toughness, vuam kev ua tau zoo, thiab kev ua haujlwm siab ua haujlwm zoo. Siv los tsim cov bolts, plowshares, chimneys, ru tsev panels, rivets, tsawg carbon steel hlau, nplooj ntawv, welded kav, khi rods, hooks, brackets, welded lug, thiab lwm yam.
Q235 yog cov hlau tsis tshua muaj carbon nrog cov ntsiab lus ntawm 0.2%. Nws muaj siab plasticity thiab zoo vuam kev ua tau zoo. Txawm li cas los xij, nws lub zog tsawg thiab nws yog qhov tsim nyog rau kev kos duab thiab dov, xws li ua cov phaj profile, thiab lwm yam.
Q345 yog cov khoom siv hlau. Nws yog cov hlau tsis tshua muaj hlau (C<0.2%) and is widely used in buildings, bridges, vehicles, ships, pressure vessels, etc. Q represents the yield strength of this material, and the following 345 refers to the yield value of this material, which is around 345 MPa. And as the thickness of the material increases, its yield value decreases.
