Grades & Application Profiles
Core Grades
• CHQ (Cold Heading): 302HQ (S30430), 304L, 305 — bolts, screws, rivets.
• Spring: 301/304HC — high work-hardening for springs/clips after drawing.
• Corrosion-resistant: 316/316L — chloride exposure, hygienic environments.
• Economical: 201/202 — cost-sensitive parts (validate corrosion class).
• Duplex: 2205 — high strength/wear-resistant drawing applications.
• Specials: 321/347/904L on request.
Chemistry/temper per ASTM A276/A479 or EN 10088-3 for rod; downstream drawn wire may target ASTM A580/A313.
End-Use Focus
• Fasteners (CHQ) — bolts, nuts, screws, rivets
• Welding Wire Feedstock — MIG/TIG solid & flux-cored wires (e.g., 308L/316L)
• Springs & Clips — automotive, appliance, general hardware
• Rope, Strand, Mesh — after multi-stage drawing
Manufacturing Route & Quality Control
- Melting & Refining — EAF + AOD refining, strict chemistry control.
- Continuous Casting — billets for long-product rolling.
- Hot-Rolling — controlled reduction; thermal and cooling control for drawability.
- Coiling — coil geometry optimized for payoff and stability.
- Annealing & Pickling (HRAP 1D) — clean, scale-free surface for drawing.
- Surface/Inclusion Checks — for EPQ; macro/decap, pinhole, and localized grind as needed.
Project-specific lube/phosphate pre-coat, peel test, microcleanliness and draw bench trials available.

Weight per Meter (stainless)
For diameter d (mm): kg/m = (π × d² / 4) × 0.00793. Examples:
• 5.5 mm → ≈ 0.19 kg/m
• 6.5 mm → ≈ 0.26 kg/m
• 8.0 mm → ≈ 0.40 kg/m
• 10.0 mm → ≈ 0.62 kg/m
• 12.0 mm → ≈ 0.89 kg/m
Use actual density/chemistry for precision; the above assumes 7.93 g/cm³.

FAQs
1) What diameter range and tolerances do you supply?
Standard diameters are 5.5–26 mm. Tolerances follow EN 10088-3 and ASTM A484 unless stricter limits are specified. For drawing-critical applications we can agree tighter ovality, straightness, and size control in the PO.
2) What is the difference between HR and HRAP (1D)?
HR is hot-rolled as-coiled. HRAP (1D) is hot-rolled, then annealed and pickled to remove scale and provide a cleaner surface that draws more consistently and is preferred for EPQ and CHQ routes.
3) CHQ vs EPQ vs Spring wire rod — how do I choose?
CHQ targets cold heading with tuned chemistry and surface for upset and forming. EPQ focuses on surface cleanliness and inclusions for bright electropolishing after drawing. Spring wire rod targets work-hardening response and elastic recovery for springs and clips.
4) Which grades are recommended for cold heading (fasteners)?
Common choices are 302HQ (S30430), 304L, and 305. They offer good ductility and lower work-hardening rates. Please share fastener class and upset ratio so we can align chemistry and anneal cycles to your tooling window.
5) What about welding wire feedstock (MIG/TIG)?
We supply rod suitable for 308L, 309L, 316L and other filler chemistries. Impurities and surface are controlled for stable multi-stage drawing and later copper-coating if required. δ-ferrite targets and analysis windows are confirmed per filler specification.
6) What coil geometry and packing do you offer?
Typical geometry is ID 800–900 mm, OD up to about 1250 mm, and 0.8–2.0 t per coil, with big-pack up to about 2.5 t on request. Export packing includes anti-rust paper, side protectors, steel banding, desiccants, pallets, and full heat/lot labels.
7) How do you manage surface defects and inclusions?
We control seams and laps via rolling practice and use annealing and pickling to remove scale. EPQ lots receive tighter surface checks and micro-cleanliness control. Optional conditioning, localized grind, and pinhole checks can be added to the order plan.
8) Can you provide pre-coat or lubrication carriers for drawing?
Yes. We can supply pickled and phosphate/soap or compatible carrier systems matched to your drawing line and die schedule. Please share your emulsion or soap type and pass sequence to select the best surface preparation.
9) What standards and documents do you support?
Materials comply with EN 10088-3 and ASTM A276/A479 with ASTM A484 general requirements. We provide EN 10204 3.1 MTRs, Certificates of Conformance, and RoHS/REACH declarations on request.
10) What are typical lead times and MOQs?
Stock grades and common diameters can ship quickly, while EPQ, CHQ, or special sizes may add time. Typical MOQ is 3–5 tons per specification. Trial coils and consolidated containers are available for new lines and multi-grade orders.
