Stainless Steel Plate Applications by Industry
MESCO's stainless steel plate is supplied to manufacturers, fabricators, and distributors across a broad range of industries worldwide.
Food Processing & Beverage Equipment
Food-grade stainless steel plate — typically Grade 304 or 316 — meets FDA 21 CFR and EU Regulation 10/2011 food contact safety requirements. The smooth, non-porous surface resists bacterial adhesion and withstands CIP (clean-in-place) chemical washing. Grade 316 is preferred for contact with brine, vinegar, or acidic food products due to its molybdenum content. MESCO supplies MTC-certified food-grade plate for tanks, conveyor systems, processing tables, and mixing vessels.
Chemical & Petrochemical Processing
Grade 316L and 2205 duplex stainless steel plate are the materials of choice for reactors, pressure vessels, heat exchangers, and pipework in corrosive chemical environments. 316L's low carbon content prevents sensitization during welding; 2205 duplex offers twice the yield strength of austenitic grades, reducing wall thickness and weight in pressure-rated equipment. ASTM A240 / ASME SA-240 compliance is available on request.
Architecture & Interior Design
Decorative stainless steel sheet in No.4 brushed, 8K mirror, and HL hairline finishes is widely used for building facades, elevator cab interiors, column cladding, and bespoke commercial furniture. Grade 304 is standard for interior use; Grade 316 is recommended for coastal or outdoor environments exposed to salt air.
Marine & Offshore
Marine applications demand maximum corrosion resistance in chloride-rich seawater environments. Marine-grade stainless steel plate (316 / 316L / 2205) is specified for boat fittings, offshore platform components, desalination equipment, and subsea structures. MESCO can supply ASTM A240 and Lloyd's / DNV type-approved material.
Pharmaceutical & Medical
Grade 316L stainless steel is the industry standard for pharmaceutical vessels, cleanroom equipment, and medical device components. Its low carbon content, biocompatibility, and smooth surface comply with ISO 13485 and USP Class VI requirements. All pharmaceutical-grade plate ships with full material documentation.
High-Temperature & Industrial Furnaces
Grade 321 and 310S stainless steel plate are engineered for continuous high-temperature service. Grade 321 is titanium-stabilized for service to 900°C; Grade 310S (25% Cr / 20% Ni) resists oxidation to 1100°C and is specified for industrial furnace components, heat treatment baskets, and kiln furniture.

Stainless Steel Plate — Frequently Asked Questions
Q1 — What is the difference between Grade 304 and Grade 316 stainless steel plate?
Grade 304 (UNS S30400 / EN 1.4301) contains 18% chromium and 8% nickel and is the most versatile, widely used stainless steel grade, offering good corrosion resistance for most indoor, food-contact, and architectural applications. Grade 316 (UNS S31600 / EN 1.4401) adds 2–3% molybdenum, which significantly improves resistance to pitting and crevice corrosion caused by chlorides, acids, and marine environments. Grade 316 is approximately 15–25% more expensive than 304 and is recommended for chemical processing, pharmaceutical, marine, and high-chloride food applications.
Q2 — What surface finishes are available, and which should I choose?
MESCO supplies five standard finishes: 2B (smooth matte, the most common industrial finish), BA (bright annealed, highly reflective), No.4 (brushed/satin, fingerprint-resistant), HL (hairline, fine continuous grain), and 8K (mirror polish). For general industrial and food processing use, 2B is the standard choice. For architectural and decorative applications such as elevator interiors, wall cladding, and commercial furniture, No.4 or HL is most common. 8K mirror is specified for luxury interiors and display fixtures.
Q3 — Do you provide a mill test certificate (MTC) with every order?
Yes. MESCO provides an original mill test certificate (MTC) complying with EN 10204 Type 3.1 with every shipment. The MTC documents the heat/coil number, chemical composition (Cr, Ni, Mo, C, Mn, Si, P, S content), mechanical properties (tensile strength, yield strength, elongation), and confirms compliance with the relevant standard — such as ASTM A240, EN 10088, or GB/T 3280. Type 3.2 certificates with third-party countersignature (SGS, Bureau Veritas, TÜV) are available on request.
Q4 — What is the minimum order quantity (MOQ)?
MESCO accepts trial orders from 1 sheet or 1 kg for standard-stocked grades and thicknesses in Grade 304 and Grade 316. For cut-to-size orders there is no minimum quantity, though a minimum per-order charge applies. For non-stocked grades (e.g., 321, 310S, 2205) or non-standard thicknesses, the minimum order is typically 500 kg to 2 metric tons depending on the grade and mill order requirements.
Q5 — What shipping and Incoterms options are available?
MESCO ships globally from Shanghai Tianjin or Ningbo ports. Available Incoterms include FOB, CIF, CFR, and EXW. In-stock orders are ready for shipment within 3–7 business days. Estimated ocean freight transit times: Southeast Asia 7–14 days, Middle East 18–22 days, Europe 25–35 days, US East Coast 30–45 days. Air freight is available for urgent small-volume trial orders.
Q6 — Which international standards do your plates comply with?
MESCO stainless steel plates are supplied to ASTM A240 (US standard), EN 10088 / EN 10028 (European standard), JIS G 4304 / G 4305 (Japanese standard), and GB/T 3280 (Chinese national standard). Cross-reference between standards is available on request. For buyers specifying ASME pressure vessel code, equivalent ASME SA-240 material is available with appropriate documentation.
Q7 — Can MESCO supply food-grade stainless steel plate for FDA or EU food contact compliance?
Yes. MESCO's Grade 304 and Grade 316 stainless steel plates are suitable for food contact applications and comply with FDA 21 CFR (US), EU Regulation 10/2011 (Europe), and GB 9684 (China). A food contact declaration can be provided upon request. For applications involving direct contact with high-chloride foods, brines, or strong cleaning chemicals, Grade 316 is recommended.
