Introduction
Cold drawn square steel is a high-precision steel product processed by cold extrusion technology, featuring smooth surface, high dimensional accuracy, and excellent mechanical properties. Formed through precise molds, the product can be directly used for various machining processes, significantly reducing material waste and processing time.
product highlights
1. High Precision Tolerance: Complies with GB/T 905, tolerance grades h8-h12, dimensional deviation ≤±0.05mm (customizable to ±0.01mm).
Polishing-Free Surface: Cold drawing ensures Ra≤1.6μm finish, eliminating polishing and reducing 30% processing costs.
High Material Efficiency: Loss rate 10%-20%, saving 30%-50% raw materials vs. traditional cutting (loss ≥50%).
Stable Mechanical Properties: Q235 yield strength ≥235MPa, elongation ≥26%; 20CrMnTi tensile strength up to 1050MPa. Custom heat treatment (annealing/quenching) available.

FAQ
Q: Can the tolerance precision meet the requirements of precision machinery assembly?
A: Standard tolerance grades are h8-h12 (dimensional deviation ≤±0.05mm). High-precision h6-h7 grades (deviation ≤±0.01mm) are available for customization, allowing direct assembly without secondary processing.
Q: What is the minimum order quantity (MOQ)? Does it support small-batch customization?
A: MOQ for standard specifications is 500kg. For non-standard customization (special sizes/materials), MOQ is 1000kg. Sample testing is supported (sample fees can be refunded for bulk orders).
Q: What is the delivery time?
A: Regular in-stock products: Shipped within 3-5 working days.
Customized products: 15-25 working days after order confirmation (including mold development time).
