Q195 Steel Coil: Properties & Applications
| Category | Details |
| Material Standard | Chinese National Standard GB/T 700 (Carbon Structural Steel), Yield Strength ≥195 MPa, Low Carbon (C ≤0.12%) |
| Form & Advantages | Coil form for easy transportation, storage, and continuous processing; smooth surface suitable for coating/spraying. |
| Key Properties | |
| - Plasticity | Elongation ≥33%, ideal for stamping, deep drawing, and cold bending. |
| - Weldability | Low carbon content reduces welding crack risks; compatible with arc welding, gas welding. |
| - Cost Efficiency | Lower cost compared to high-strength steels (e.g., Q235), ideal for low-stress applications. |
| Primary Uses | |
| - Construction | Lightweight structural components (purlins, brackets), guardrails, metal roofing, security grilles. |
| - Hardware | Nails, rivets, washers, toolboxes, metal containers. |
| - Appliances/Furniture | Washing machine drums, refrigerator casings, chair/table frames, metal cabinet skeletons. |
| - Industrial Support | Cable trays, ventilation ducts, non-load-bearing vehicle parts. |
| Processing Methods | |
| - Cold Working | Shearing, bending, punching, cold rolling. |
| - Surface Treatment | Galvanizing, powder coating, painting (pre-treatment required). |
| Limitations | |
| - Strength Limits | Unsuitable for high-stress applications (bridges, heavy machinery); use Q235 or higher-grade steel. |
| - Corrosion Protection | Requires coating or plating in humid environments. |
