PRODUCT DESCRIPTION
Built for fabricators who live by first-time-right welding and predictable forming, this product line pairs ASTM A285M Gr.B with Q195 black iron plate to cover low-to-intermediate strength pressure-vessel and general fabrication workloads. Expect a steady, quiet fit-up at the press brake and a clean arc sound at the weld—thanks to controlled chemistry and tight thickness tolerances. Cold-rolled surfaces deliver a satin-smooth feel that resists galling in dies; hot-rolled surfaces bring the dark, graphite-like mill finish that shrugs off workshop handling. In tanks, housings, and structural skins, the steel’s combination of ductility and stability translates into fewer reworks and faster cycle time. For OEMs and EPCs, that means simpler PPAPs, faster FATs, and fewer vendor NCRs. The result: a practical, durable material platform that reduces schedule risk while keeping total installed cost in check.

How to use these parameters in sourcing: treat the two width and thickness windows as your “standard” and “extended/custom” ranges during RFQ. If you are routing coils to service centers, the coil weight window (2–20 t) helps plan decoiling and slit-coil logistics. For export jobs, combine the oiled surface with VCI wrap for longer sea legs.
Predictable forming window: HR2/Q195 options deliver compliant drawing and bending behavior, reducing die stick-slip and scrap—good news for high-volume stampings.
Weldability with headroom: Low-to-intermediate strength chemistry supports conventional FCAW/GMAW procedures and keeps HAZ toughness consistent, streamlining WPS/PQR reuse.
Surface tailored to process: Cold-rolled sheets feel smooth to the touch for paint-ready skins; hot-rolled plates offer a robust, matte black finish that tolerates handling and tack-weld cleanup.
Pressure-vessel suitability: A285M Gr.B supports low-to-moderate pressure duty, enabling economical tankage and housings without over-spec’ing higher-cost alloys.
Tight thickness control: Minimizes shim packs and grinding time, improving assembly takt and dimensional stability.
Procurement simplicity: MOQ from 5 tons, fast sampling, and flexible payment terms keep projects moving when schedules tighten.
Pressure vessels & tanks: shells, heads, reinforcing pads, manway rings for water, fuels, and benign chemicals.
Thermal equipment: low-temperature boiler components, housings, and guards where consistent forming and weldability matter.
General fabrication: architectural cladding, frames, brackets, and machine covers where a clean surface and uniform gauge shorten downstream finishing.
Automotive & appliance back-plates: cold-rolled surfaces provide stable paint adhesion and a smooth, uniform look.
Infrastructure & OEM skids: baseplates, stiffeners, and enclosures that need a tough, black mill finish and reliable cut quality.
ASTM A285M Gr.B: pressure-vessel quality, low/intermediate tensile range; suitable for welded vessel applications.
Q195 carbon steel sheet (often marketed as “black iron”): widely used low-carbon grade; commonly cross-referenced to S185 / 1.0035 in EN systems.
HR2: hot-rolled drawing-quality sheet designation used for formable applications.
U11952: Chinese structural-quality designation present on the listing; available on request for project matching.
If your BOM references A285B, Q195, S185/1.0035, or HR2, we can align melt practices and test certificates to your document set.
Processing services: precision cutting (laser/plasma), decoiling & leveling, slitting, beveling, and surface oiling.
Inspection & testing: heat-by-heat chemistry, mechanical tests, and dimensional checks; optional UT where project specs require it.
Certificates: Mill Test Certificate (3.1) and full lot traceability upon request; packaging meets seaworthy export standards with edge protectors and VCI options.
Lead time & logistics: standard production slots with agile consolidation; MOQ 5 tons supports pilot builds, while frequent sailings keep global sites on schedule.
Data package: we can supply a single PDF bundle (CoA, MTC, packing list) matched to your PO and drawing numbers to simplify receiving and PPAP/FAT file builds.
Supply assurance: active stock position and monthly output up to 20,000–30,000 t help you absorb demand spikes without premium expediting.
Practical customization: dual windows for width/thickness and multiple surface states let you dial in the exact formability and finish needed.
Total cost focus: predictable forming and welding behavior lowers rework, while precise thickness reduces finishing time—savings that persist across volumes.
Ease of doing business: flexible payment terms (T/T, L/C, PayPal), free samples for trials, and responsive technical support shorten the path from RFQ to first article.
Q1: How do I choose between A285M Gr.B and Q195 for my build?
If you’re designing for pressure-bound service (e.g., tanks, housings under benign pressure), A285M Gr.B provides a pressure-vessel pedigree and a defined tensile/elongation envelope. For non-pressure structural skins, brackets, or drawn parts, Q195/HR2 gives you a friendlier forming window and cost-efficiency.
Q2: What finish should I pick if I plan to paint?
Cold-rolled with light oiling offers the smoothest, paint-ready feel and consistent film build. For rugged frames and baseplates, hot-rolled black finish is durable and easy to prep—just a quick mechanical clean before primer.
Q3: Can you match my certificate stack and revision control?
Yes. We issue heat-specific MTCs and can align data to your PO, drawing, and revision codes. If you require UT or additional mechanical tests, specify them in the RFQ so we can block capacity and include them in the CoA.
Q4: What is the typical coil weight and how does it affect my service-center plan?
Coil weights run 2–20 tons per our listing. Heavier coils reduce changeovers on slit lines; lighter coils help minimize tail-end scrap on short runs. Tell us your decoiler and max mandrel load—we’ll stage coils accordingly.
