What is Q195 steel? Is it suitable for making nails?
Q195 is a low-carbon structural steel (C≤0.12%) according to GB/T 700 standard, with a yield strength ≥195MPa. It boasts excellent plasticity, toughness, and cold workability, and is low in cost, making it the preferred mainstream material for ordinary round nails, woodworking nails, and galvanized nails.
What are the core advantages of using Q195 steel plate for nails?
① Less prone to cracking during cold drawing/stamping/capping, resulting in low processing loss; ② Good toughness, making nails less prone to bending and breakage during driving; ③ Low price, suitable for large-scale mass production; ④ Easy to galvanize/polish, adaptable to various surface treatments.
What are the disadvantages of using Q195 steel for nails?
Relatively low strength (tensile strength 315–430MPa), unsuitable for high-strength/heavy-load/concrete nails; prone to rust when used bare, requiring surface treatment.
Does the nail industry use Q195 steel plate or wire rod?
The mainstream material used is Q195 wire rod (coiled wire) cold-drawn into wire; steel plates are mostly used for stamping rivets/studs/special shaped rivets, or as raw material for steel strip wire cutting.
What international grades correspond to Q195?
American Standard SAE1006/1008, Japanese Standard SS330, German Standard St33, and British Standard 040A10. Their compositions and properties are similar and they are interchangeable.
