Q195 Steel Properties and Introduction

Q195 steel is a Chinese plain carbon structural steel, yield strength: 195 MPa, tensile strength: 315-430 MPa, material density: 7.85 g/cm3. “Q” is the first letter of Chinese spelling of “qu fu dian”, the translation is “Yield Point” or “Yield Strength”, “195” is indicates the unit value “195 MPa”. Datasheet is tested with 16mm thickness steel bars or steel plates.

The latest standard of Q195 steel is GB/T 700 – 2006, for chemical composition, mechanical properties and equivalent, please see the following tables.

 

Q195 Material Features and Applications

Q195 material 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.

Other applications includes making steel pipes, steel angle, anchor bolts, chimneys, roofing slabs, rivets, tie rods, hooks, brackets, welded structures, etc.
