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 slightly lower yield strength (≥ 195 MPa), making it ideal for applications requiring higher ductility. Q235 contains slightly more carbon (0.14–0.22%) and delivers greater yield strength (≥ 235 MPa), making it more suitable for structural reinforcement in skyscrapers and bridges.
What applications is SWRH82B prestressed wire rod best suited for?
SWRH82B prestressed wire rods are engineered for demanding structural applications that require high tensile strength (≥ 1320 MPa) and seismic resistance. They are primarily used in large-scale infrastructure projects such as bridges, high-rise building foundations, and prestressed concrete structures.
Why is SAE1008 wire rod preferred for cold-heading applications?
SAE1008 wire rods feature tightly controlled low carbon content (0.06–0.10%) and excellent ductility metrics, including elongation ≥ 30% and reduction of area ≥ 65%. These properties allow the material to withstand the high deformation forces of cold-heading processes, making it ideal for producing high-strength bolts, bearings, and precision hardware components.
What makes 30CrMo alloy wire rods suitable for extreme temperature environments?
30CrMo alloy wire rods contain chromium (0.80–1.10%) and molybdenum (0.15–0.25%), which significantly enhance high-temperature strength and oxidation resistance. With a yield strength of ≥ 550 MPa at 550°C, these rods are well-suited for oil drilling equipment, 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, and suitability for global supply chains across multiple industries.
