Q195 Steel Chemical Composition, Mechanical Properties, Specification and Equivalent
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.
The following tables show Q195 steel specification and equivalent

Dear Sir
I have a question about the chemical composition percent for Q195 steel.
Inside Q195 steel is:
Carbon (C ) 0.12%
Silicon (Si) 0.30%
Manganese (Mn) 0.50%
Phosphorous (P) 0.035%
Sulfur (S) 0.04%
Total 0.995%
100% – 0.995% = 99.005 percent remainder
What material is the remainder 99.005 % made of? Is it 99.005% Iron (Fe) ?
Thank you
Yes, it’s correct, the remainder of materiel is Iron (Fe), thanks for your comment.
we required the following material-
Steel wire (Dia – 1.8 to 2.5 mm) Galvanized spring steel wire
Hi, we don’t sell steel products, and Q195 can’t be used for spring steel wire, for spring steel wire, you should use high carbon steel, such as 65, 65Mn, 70, 70Mn, 1065, 1075, 1095, etc.

Thanks for the great information, do you know Youngs Modulus of Q195?
dear sir,
what are the chemical composition for 16mm ms wire rod for bolt manufacturing
Hello,
Is there an index to follow Q195 steel prices? A website?
Thank you for your help,
What the best wire rod for bolt grade 4.8
What is the cleanliness class of the wire?
Its critical to know, as the wire we are looking for will be galvanized
