CARBON STEEL H PROFILE Q195 HW is Chinese steel grade of carbon structural steel, “Q” stands for Yield Strength, “195” means the Yield Strength is 195 Mpa, and Tensile Strength is 315 – 430 Mpa, data is tested based on a 16mm diameter steel bar. Q195 material density is 7.85 g/cm3, the physical properties and chemical composition are equivalent to ASTM – Gr.B(σs185), Gr.C(σs205); DIN – St33, S185; JIS – SS330(σs205), SPHC(σs205), SPHD(σs205); BS – 040A10, S185(σS185MPa).

CARBON STEEL H PROFILE Q195 HW has high plasticity, toughness and weldability, good pressure and processability, but low strength. It has many uses, such as the manufacture of wire rods, steel plates. Wire rods can be cold drawn into low carbon steel wires, then to make black or galvanized iron wire, tie wire, welded wire mesh, wire fence, and many more; Cold and hot-rolled steel sheets are widely used in roofing panels, decorative panels, packaging containers, iron drums, instrument cases, switch boxes, protective covers, etc.
