Q:What is the chemical composition of Q195?
A:Carbon (C): ≤0.12%, belongs to low carbon steel, ensures good weldability and cold workability.
Manganese (Mn): ≤0.50%, helps to improve strength but does not affect plasticity.
Sulfur (S), phosphorus (P): ≤0.040%, low impurity content, ensure material purity.
Q:Q195 What are the core advantages of galvanized steel?
A:Economical: Q195 is one of the lowest-cost grades of carbon steel and is suitable for large-scale applications. Processing adaptability: High plasticity and weldability make it easy to cold-bend and weld, suitable for manufacturing complex structural parts (such as steel pipes and iron wires).
Surface quality: The surface flatness of the cold-rolled substrate (SPCC) is high, suitable for direct painting or galvanizing.
Q:Can Q195 be used in the construction industry?
A:In the construction industry, Q195 is commonly used for:
Structural parts: light steel keels, scaffolding, transmission towers, taking advantage of its weather resistance and low-cost maintenance.
Pipeline system: hot-dip galvanized steel pipes (DN25-DN150) are used for water heating circulation and fire protection pipelines, with a coating thickness of ≥60μm to resist water corrosion.
Q:Can Q195 be used in the automotive manufacturing industry?
A:In the automotive manufacturing industry, Q195 is commonly used for:
Non-load-bearing parts: frame longitudinal beams, interior brackets. The plasticity of Q195 is suitable for cold bending, and the coating can resist road salt erosion.
Agricultural machinery: tractor frames, harvester parts, taking into account both strength and rust prevention requirements.
Q:Can we see Q195 in daily life?
A:Q195 is commonly used in
Furniture and home furnishings: shelves, fences, air conditioning brackets, the surface can be directly sprayed or kept in the original galvanized color.
Packaging materials: galvanized steel strips are used for carton packaging and wire mesh, which are low-cost and reliable in anti-rust performance.
