❓ 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 higher elongation (≥33%), making it ideal for highly ductile applications. Q235 contains slightly more carbon (0.14–0.22%), offering a higher yield strength (≥235 MPa) and is more commonly used in structural reinforcement for concrete in skyscrapers and bridges.
Q
What makes SWRH82B wire rods suitable for prestressed applications?
SWRH82B wire rods feature a high carbon content (0.80–0.85%) that delivers exceptional tensile strength (≥1320 MPa) and yield strength (≥1180 MPa). These properties allow them to withstand sustained tensile loads and seismic forces, making them the preferred choice for prestressed concrete structures in large-scale infrastructure projects.
Q
Why is SAE1008 wire rod preferred for cold-heading applications?
SAE1008 wire rods are engineered with ultra-low carbon content (0.06–0.10%) and tightly controlled P/S levels (≤0.030%), resulting in outstanding ductility — elongation ≥30% and reduction of area ≥65%. These characteristics prevent cracking during high-precision cold-heading processes used to manufacture bolts, bearings, and hardware components.
Q
In what extreme environments can 30CrMo alloy wire rods be used?
30CrMo alloy wire rods are specifically designed for high-temperature and corrosive environments. With a yield strength of ≥550 MPa at 550°C, they are widely applied in oil drilling wires, wind turbine tower anchor bolts, and aerospace fasteners where both heat resistance and mechanical integrity are critical.
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). All products undergo strict quality control focusing on carbon content accuracy, elongation performance, and surface defect minimization.
