❓ Frequently Asked Questions
Q
What is the difference between Q195 and Q235 low-carbon wire rods?
Q195 has a lower carbon content (C ≤ 0.12%) and offers higher ductility with a yield strength of ≥195 MPa, making it ideal for welding electrodes and light structural parts. Q235 contains slightly more carbon (0.14–0.22%) and achieves a higher yield strength of ≥235 MPa, making it more suitable for concrete reinforcement rebar in skyscrapers and bridges where greater structural load is required.
Q
What applications are SWRH82B prestressed wire rods best suited for?
SWRH82B prestressed wire rods are engineered for large-scale infrastructure projects requiring exceptional load-bearing capacity and seismic resistance. With a tensile strength of ≥1320 MPa and yield strength of ≥1180 MPa, they are commonly used in prestressed concrete structures, suspension bridges, and high-rise building frameworks.
Q
Why is SAE1008 wire rod preferred for cold-heading applications?
SAE1008 wire rods feature tightly controlled low carbon content (C 0.06–0.10%) and very low phosphorus/sulfur levels (P/S ≤ 0.030%), resulting in excellent ductility — elongation ≥30% and reduction of area ≥65%. These properties allow the material to undergo high-precision cold-heading without cracking, making it the preferred choice for manufacturing high-strength bolts, bearings, and hardware components in the automotive and home appliance industries.
Q
What makes 30CrMo alloy wire rods suitable for extreme environments?
30CrMo alloy wire rods contain chromium (Cr 0.80–1.10%) and molybdenum (Mo 0.15–0.25%), which significantly enhance high-temperature strength and corrosion resistance. These rods maintain a yield strength of ≥550 MPa even at 550°C, making them ideal for oil drilling wires, wind turbine tower anchor bolts, and aerospace fasteners operating under extreme thermal and mechanical stress.
Q
What international standards do your wire rods comply with?
Our wire rods are manufactured in compliance with major international standards including ASTM (American Society for Testing and Materials), GB/T (Chinese National Standards), and JIS (Japanese Industrial Standards). Material selection guidance prioritizes carbon content, elongation performance, and surface defect control to meet the specific requirements of each downstream application.
