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 offers higher elongation, making it ideal for applications requiring excellent ductility. Q235 contains slightly more carbon (0.14–0.22%) and provides higher yield strength (≥235 MPa), making it more suitable for structural reinforcement in skyscrapers and bridges.
What applications are SWRH82B prestressed wire rods best suited for?
SWRH82B prestressed wire rods are engineered for large-scale infrastructure projects that demand high tensile strength (≥1320 MPa) and seismic resistance. They are commonly used in prestressed concrete structures, cable-stayed bridges, and high-rise building frameworks where load-bearing performance is critical.
Can SAE1008 cold-heading wire rods be used for automotive parts manufacturing?
Yes. SAE1008 wire rods feature tightly controlled carbon content (0.06–0.10%) and exceptional ductility (elongation ≥30%, reduction of area ≥65%), making them ideal for high-precision cold heading processes. They are widely used to manufacture high-strength bolts, bearings, and hardware components that serve both automotive and home appliance supply chains.
What makes 30CrMo alloy wire rods suitable for extreme environments?
30CrMo alloy wire rods contain chromium (0.80–1.10%) and molybdenum (0.15–0.25%), which significantly enhance high-temperature strength and corrosion resistance. With a yield strength of ≥550 MPa at 550°C, they are well-suited for oil drilling wires, wind turbine anchor bolts, and aerospace fasteners operating under extreme thermal and mechanical stress.
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). This ensures consistent quality, dimensional accuracy (±0.1 mm), and suitability for global downstream processing and construction applications.
