Q275 H Steel Beam
Introduction to Q275
Q275 is a carbon structural steel, corresponding to the old brand A5, and belongs to the hot-rolled steel plate.
Q275 structural steel has high strength, good plasticity, and cutting performance, as well as certain welding performance. Small parts can be quenched and strengthened, and are mostly used for manufacturing parts with high strength requirements, such as gears, shafts, sprockets, keys, bolts, nuts, agricultural machinery steel profiles, conveyor chains, and chain links.
