Frequently Asked Questions
What is the difference between Q195 and Q235 low-carbon wire rods?
Q195 has a lower carbon content (C ≤ 0.12%) and a minimum yield strength of 195 MPa, making it suitable for lighter structural applications. Q235 contains slightly more carbon (0.14–0.22%) and offers a higher yield strength of 235 MPa, making it more appropriate for structural concrete reinforcement in skyscrapers and bridges where greater load-bearing capacity is required.
What makes SWRH82B wire rods suitable for prestressed concrete applications?
SWRH82B wire rods feature a high carbon content (0.80–0.85%) that delivers exceptional tensile strength of ≥1320 MPa and yield strength of ≥1180 MPa. These properties allow the wire to sustain significant pre-tension loads without permanent deformation, meeting the strict load-bearing and seismic resistance requirements of large-scale infrastructure projects.
Why is SAE1008 wire rod preferred for cold-heading processes?
SAE1008 wire rods are engineered with very low carbon (0.06–0.10%) and tightly controlled phosphorus and sulfur levels (P/S ≤0.030%), resulting in outstanding ductility — elongation ≥30% and reduction of area ≥65%. This high ductility allows the material to be cold-headed into complex shapes such as high-strength bolts, bearings, and hardware components without cracking or surface defects.
What industries use 30CrMo alloy wire rods?
30CrMo alloy wire rods are designed for extreme operating conditions. Their chromium and molybdenum content provides excellent heat resistance (yield strength ≥550 MPa at 550°C) and corrosion resistance, making them ideal for oil and gas drilling wires, wind turbine tower anchor bolts, and aerospace-grade fasteners where reliability under high stress and temperature is critical.
What international standards do your wire rods comply with?
Our wire rods are manufactured and tested in compliance with major international standards including ASTM (American Society for Testing and Materials), GB/T (Chinese National Standards), and JIS (Japanese Industrial Standards). This ensures that our products meet the chemical composition, mechanical performance, and surface quality requirements for global markets and diverse industrial applications.
Can wire rods be customized for specific project requirements?
Yes. As a global wire rod supplier, we offer full customization options including specific alloy compositions, dimensional tolerances (±0.1 mm precision), surface treatments such as Galfan® galvanized coatings, and tailored mechanical property targets.
