Ultimate Stainless Steel Metal Plate | S31600 & 2B Surface

Product Specifications

Key Properties

Tensile Strength

S31600 stainless steel plates deliver exceptional tensile strength of ≥520 MPa and yield strength of ≥205 MPa, making them ideal for structural and load-bearing applications. The high nickel (10–14%) and molybdenum (2–3%) content enhances ductility, achieving an elongation of ≥40%, which prevents brittle fractures under stress. Compared to plated steel vs stainless steel, S31600 offers superior integrity in corrosive environments due to its homogeneous alloy structure.

Bending Strength

With a bending strength optimized for cold-forming processes, S31600 withstands tight-radius bends without cracking. The material’s n-value (strain hardening exponent) of 0.35–0.45 ensures uniform deformation, even in porcelain vs stainless steel grill heat plates applications requiring high-temperature resistance up to 870°C. Post-welding, the heat-affected zone retains ≥90% of the base metal’s strength, critical for pressure vessel fabrication.

Identification & Weight Calculation

Marking Methods

• Laser Etching: Permanent UNS S31600 grade marking on edges.
• Heat-Resistant Stencils: Visible identification for high-temperature applications like porcelain vs stainless steel grill heat plates.
• QR Codes: Traceability linked to batch-specific chemical and mechanical test reports.

Weight Formula

$\text{Weight (kg)}=\text{Thickness (mm)}\times \text{Width (m)}\times \text{Length (m)}\times 7.98(\text{Density})$
Example: A 5 mm × 1.2 m × 2.4 m plate weighs 5 × 1.2 × 2.4 × 7.98 = 114.91 kg.

Why Stainless Steel May Corrode?

Although S31600 is highly corrosion-resistant, specific conditions can trigger rust:

1. Chloride Exposure: Prolonged contact with seawater or de-icing salts may cause pitting. However, S31600’s molybdenum content provides 50% higher pitting resistance than 304 stainless steel.
2. Mechanical Damage: Scratches or grinding can disrupt the passive chromium oxide layer. Our 2B surface finish minimizes surface defects through controlled cold-rolling.
3. Galvanic Corrosion: Contact with carbon steel or copper alloys in humid environments. Use insulating gaskets for perforated stainless steel plate installations.
4. High-Temperature Oxidation: Continuous exposure above 870°C degrades chromium’s protective oxide. For extreme heat, consider ceramic-coated porcelain vs stainless steel grill heat plates.
