Corrosion Resistance
Our stainless steel flat stock contains a minimum of 10.5% chromium, forming a passive oxide layer that resists rust and chemical corrosion.
Enhanced grades like 316L include molybdenum (2–3%) for superior resistance to chlorides and acidic environments
High Strength & Durability
Cold-rolled variants offer increased tensile strength (up to 1,020 MPa) and hardness, making them ideal for structural applications.
Duplex grades (e.g., 2205) combine austenitic and ferritic properties for exceptional strength-to-weight ratios.
Versatile Surface Finishes
Choose from polished (mirror 8K), brushed (HL), or embossed surfaces to meet aesthetic or functional needs.
Precision Manufacturing
Produced via hot/cold rolling and annealing, our stainless steel flat bar ensures dimensional accuracy (±1% tolerance) and uniform thickness.

Certified Quality
Compliant with ISO 9001, RoHS, and ASTM standards.
Third-party inspections ensure chemical composition and mechanical properties meet specifications.
Customization Options
Tailor thickness, width, and surface finishes for applications like stainless steel flat top grill components, architectural frameworks, or industrial machinery.
Fast Delivery & Global Logistics
Lead times as short as 7–15 days, with FOB/CFR/CIF terms available.

Construction: Beams, supports, and decorative trims.
Food Processing: Stainless steel flat top grill surfaces, hygienic equipment.
Marine Engineering: Corrosion-resistant fasteners and fittings.
Automotive: Exhaust systems, chassis components.

Calculate weight using the formula:
$Weight (kg) = Thickness (mm) \times Width (m) \times Length (m) \times Density (g/cm³)$

Density: 7.93 g/cm³ (304/316), 7.75 g/cm³ (430).
Example: A 1m × 1m × 3mm 304 sheet weighs $3 \times 1 \times 1 \times 7.93 = 23.79 kg$ .

Despite its name, stainless steel flat bar can rust under specific conditions:

Electrochemical Corrosion
Contact with dissimilar metals (e.g., carbon steel) in humid environments creates galvanic cells.
Chemical Exposure
Chlorides (seawater) or acids degrade the passive layer, leading to pitting.
Mechanical Damage
Scratches or abrasions expose raw metal to oxygen and moisture.
