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 an elongation rate of ≥33%, making it suitable for fine-drawing applications. Q235 contains slightly more carbon (C 0.14–0.22%), providing a higher yield strength of ≥235 MPa, making it the preferred choice for rebar and structural reinforcement in skyscrapers and bridge projects.
Q What 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 Standard), and JIS (Japanese Industrial Standard). We can provide full material test reports and certifications upon request.
Q Is SWRH82B wire rod suitable for seismic-resistant construction?
Yes. SWRH82B prestressed wire rods feature a tensile strength of ≥1320 MPa and a yield strength of ≥1180 MPa, meeting demanding load-bearing and seismic resistance requirements. They are widely used in prestressed concrete elements for large-scale infrastructure projects such as bridges, high-rise buildings, and underground structures.
Q What makes 30CrMo alloy wire rods suitable for aerospace and oil drilling applications?
30CrMo alloy wire rods contain chromium (Cr 0.80–1.10%) and molybdenum (Mo 0.15–0.25%), which significantly enhance their high-temperature resistance and corrosion resistance. With a yield strength of ≥550 MPa even at 550°C, these rods are engineered for extreme-condition applications including oil drilling wires, wind turbine anchor bolts, and aerospace-grade fasteners.
Q Can SAE1008 wire rods be customized for automotive supply chains?
Absolutely. SAE1008 cold-heading steel wire rods are specifically designed for high-precision cold forming processes. With an elongation ≥30% and reduction of area ≥65%, they are ideal for producing high-strength bolts, bearings, and precision hardware components used in automotive manufacturing and home appliance production lines. Custom dimensions and surface treatment options are available.
Q How do I choose the right wire rod grade for my project?
Material selection should be based on the specific mechanical requirements, environmental conditions, and downstream processing methods of your project. Key factors to evaluate include required tensile and yield strength, carbon content, elongation rate, and surface quality. Our technical team can assist you in identifying the optimal grade — whether low-carbon, high-carbon, or alloy — and provide customized product catalogs and technical documentation to support your procurement decision.
