Q235A carbon structural steel GB/T Q235A low carbon steel

Q235A Carbon Low-alloy Steel Description

Q235A carbon structural steel has good toughness and plasticity, certain elongation, good welding performance and hot workability. in the grade Q235b, 235 means the yield strength is 235Mpa, q means the yield limit of the steel, and the A value is not required for the impact toughness test. Q235A carbon steel is generally used in the hot-rolled state, and the rolled section steel, steel bar, steel plate and steel pipe can be used in the manufacture of various welding Structural parts, bridges and some common mechanical parts such as bolts, tie rods, rivets, collars and connecting rods.

Q235A plain carbon and low-alloy steel belongs to low carbon steel, because of its low carbon content, it has certain corrosion resistance and good heat resistance. q235a plain carbon steel has good ductility and can be used to manufacture various complex parts Excellent resistance to thermal deformation, so it is widely used in automobile manufacturing, ships, machinery, construction, household appliances and other fields. There are two forms of q235a plain carbon steel, one is hot-rolled and the other is cold-rolled. The cold-rolled form has better mechanical properties than the hot-rolled form, which can better meet the requirements of users, but cold-rolled The rolled form is also slightly more expensive than the hot rolled form.

GB/T Q235A low carbon steel has good mechanical properties and can be used to manufacture various complex parts. It has good tensile strength, plasticity and welding properties, and can realize more complex structures and parts. The processing performance of q235a plain carbon steel is good, whether it is cold processing or hot processing, it can be well realized, and the cutting performance is also good, which can effectively improve the processing efficiency and is suitable for mass production.
