Multiple Common Grades of Stainless Steel Sheets
If you have any other needs or require customization, please feel free to contact us.
Common austenitic stainless steel, 304L can improve weldability and reduce carbide precipitation, and very suitable for large processing projects.
Containing molybdenum and with excellent chloride resistance and marine corrosion resistance, 316L stainless steel sheets are the first choice for welded structures.
An economical ferritic stainless steel with good corrosion resistance and strong magnetic properties.
Containing high chromium and nickel, and has excellent high temperature resistance and oxidation resistance, ideal for furnace parts and heat insulation covers.
Titanium-stabilized stainless steel, suitable for high temperature welding, can resist sensitization and intergranular corrosion.
Containing higher alloy than 309 stainless steel, commonly used for extreme high temperature environments, and has excellent oxidation resistance and high temperature strength.
The Grade of Stainless Steel Sheets You Should Choose
There are so many grades of stainless steel sheets to choose, Spark X provide grades including but not limited to the following: 301, 302, 304/304L, 316/316L, 317L, 201/202, 430/430Ti, 321, 309S, 310S, 321, 330, 347, 409/409L, 410, 430, 440C, 439/441/444, 317L, 904L, 2205, 17-4, 17-7, A286 (others on request)
Commonly used stainless steel sheets are primarily austenitic grades 304 and 316, widely applicable, corrosion-resistant, and easily formed. Each batch of SparkX comes with an EN10204 3.1 material certificate, ensuring traceability of composition and batch number.
How Much Stainless Steel Sheet Finishing Matters
Spark X provides a complete stainless steel sheet finishing treatment system:
Rolled/annealed base surfaces: 2D, 2B, BA, No.1 (HRAP);
Mechanically polished/brushed: No.3, No.4, HL (hairline), Vibration;
High gloss and textured: 8K/No.8 (mirror), bead-blasted, etched, and embossed;
Decorative and functional: PVD ion coloring, anti-fingerprint coating, pickling/passivation.
The most common problem with brushed/hairline boards is color variation and inconsistent grain direction, resulting in uneven surface finish after splicing and easy rework.
Spark X utilizes homogenous master roll management for stainless steel sheet finishing and standardized abrasive/line speed process cards. Samples are locked, and the target Ra is agreed upon before ordering. Grain direction is marked throughout production and shipment, ensuring consistent grain direction across batches. We also support your composite solutions (e.g., brushed + PVD, mirror + AF, sandblasting + PVD, etching + PVD), ensuring consistent delivery based on project sample, color, and preferred grain direction.
How You Cut Stainless Steel Sheet
Our cutting process for stainless steel sheets utilizes an integrated in-house process: coil flattening (CTL) → slitting → CNC shearing → laser/waterjet precision cutting → edge trimming/chamfering → film application and packaging. This ensures your stainless steel sheet meets the required assembly dimensions upon shipment, so you don’t need on-site grinding and rework.
Brushed/HL stainless steel sheets are cut in the direction of the grain, ensuring a consistent assembly finish and a cleaner appearance. Mirror and colored stainless steel sheets are fully protected with PE film from the start of flattening, effectively protecting your goods from scratches during handling. Edge trimming and chamfering ensure precise weld and assembly contact edges, simplifying installation.
We provide coils and cut-to-length sheets/plates. Typical range: thickness 0.30–3.0 mm (CR) and 3.0–16+ mm (HR); width 1000/1219/1500/1524/1800/2000 mm; length 2000/2438/2500/3000/3048/4000/6000 mm. Typical shop tolerances: shearing ±1–2 mm; laser/waterjet ±0.2–0.5 mm; flatness per ASTM A480 (to be confirmed on PO). Options include PE film, edge finishing (fine trim/chamfer), and grain-direction marking for brushed/HL surfaces.
Price depends on grade (Ni/Mo content), thickness, width, length, finish (2B/BA/No.4/HL/8K, PVD, anti-fingerprint), quantity/MOQ, processing (slitting, CTL, edge finishing), packaging & Incoterms (FOB/CIF/DDP), and market surcharges. Please let us know your requirements (grade, finish, size, quantity, destination), and we’ll quote within 24 hours. We also suggest cost-down options such as width optimization (less scrap), alternative finishes, or coil vs sheet, so you get the best landed cost.
Typical uses include architectural façades, interiors, elevators & public interiors, commercial kitchen equipment, home appliances & enclosures, chemical & water-treatment cladding, marine, offshore, automotive trim, exhaust, heat shields, and general sheet metal OEM. Tell us your environment, such as chloride, hygiene, outdoor, and we’ll match suitable grades 304/316L/430/441/444/2205 and finishes 2B/BA/No.4/HL/8K for durability and consistent appearance.
