SS 904L Plate for Vietnam’s Chemical Industry – Corrosion-Resistant Steel Exporter

Table of Contents

Looking for reliable suppliers of SS 904L stainless steel plates for your chemical processing plants in Vietnam? Hindustan Steel Corporation offers export-grade 904L plates engineered for superior corrosion resistance in harsh chemical environments. With a ready inventory, global logistics, and technical support, we are a preferred partner for stainless steel in Vietnam’s industrial sector.

What is SS 904L Stainless Steel and Why It’s Ideal for Chemical Applications?

SS 904L (UNS N08904 / WNR 1.4539) is a low-carbon, high-alloy austenitic stainless steel known for its exceptional resistance to sulfuric acid, chlorides, phosphoric acid, and other aggressive chemicals. It contains high levels of nickel (23-28%) and molybdenum (~4%), making it suitable for acid tanks, reactors, scrubbers, and piping in fertilizer, petrochemical, and acid-processing plants.

This grade offers advantages over SS 316L and duplex grades in highly corrosive conditions, especially in Vietnamese chemical plants exposed to saline humidity, high chloride levels, and acidic reactions.

Key Applications of SS 904L Plates in Vietnam’s Industrial Sector

We export SS 904L stainless steel plates to chemical processing industries across Vietnam, including:

  1. Fertilizer production (phosphoric and sulfuric acid equipment)
  2. Chlor-alkali plants and brine electrolysis systems
  3. Acid pickling tanks and chemical storage vessels
  4. Petrochemical desulfurization units
  5. Marine chemical discharge piping
  6. Pulp & paper bleaching equipment

Its excellent formability and weldability make it a top choice for fabrication of reactors, vessels, and heat exchangers in both greenfield and maintenance projects.

Mechanical Properties and Performance of SS 904L Plate

SS 904L plates deliver high strength with excellent ductility and corrosion resistance:

Property Typical Value
Tensile Strength (MPa) 490 – 710 MPa
Yield Strength (0.2% offset) ≥ 220 MPa
Elongation ≥ 35%
Hardness (Brinell) ≤ 220 HBW
Impact Toughness (at RT) High
Operating Temp. Range -50°C to 400°C

Even in hot and humid coastal zones of Vietnam, SS 904L offers long-term corrosion resistance against acids and chlorides.

Global Standards & Vietnamese Compliance for SS 904L Plates

Our SS 904L stainless steel plates conform to major international and regional specifications, ensuring full compatibility with Vietnamese chemical industry requirements:

  • ASTM A240 / ASME SA240 – Plate specification for 904L
  • EN 10088-2 (1.4539) – European norm for corrosion-resistant stainless steel
  • NACE MR0175 / ISO 15156 – Sulfide stress cracking resistance
  • PED / AD 2000-W0 – Pressure equipment certifications for vessels
  • ISO 9001 / Mill TC EN 10204 3.1 / 3.2

We also help Vietnamese importers meet customs documentation, plant certifications, and project-specific technical approvals.

Thickness Range & Plate Sizes for Export to Vietnam

We supply SS 904L plates in custom sizes and ready stock thicknesses, suitable for tank fabrication, lining, and cladding in chemical facilities.

Thickness Widths Available Lengths
3 mm – 50 mm 1250 mm / 1500 mm / 2000 mm 2500 mm / 5000 mm / Custom Cut
Coil Form 0.5 mm – 5 mm As per requirement
  • Cut-to-size export packing
  • Plasma & waterjet cut pieces
  • Surface finish: No.1, 2B, BA, or Mirror Polish (for clean room zones)

Corrosion Resistance & Heat Performance in Acid Plants

SS 904L stainless steel is highly effective in resisting:

  • Hydrochloric and sulfuric acid vapors
  • Pitting from high chloride content in marine zones
  • Intergranular corrosion in hot acid storage
  • Stress corrosion cracking in humid environments

In Vietnam’s tropical climate and coastal industry zones (like Hai Phong, Da Nang, Ho Chi Minh), 904L performs far better than SS 316L or SS 317L.

Fabrication, Machining & Welding Guidance

SS 904L is known for its excellent formability, weldability, and machinability:

  • Welded using TIG, MIG, or SMAW techniques
  • Use of E309MoL or E385 filler wire for best corrosion properties
  • Machining requires rigid tools and low cutting speeds
  • Cold or hot forming is possible with proper annealing

We also offer ready-to-use profiles and pre-fabricated parts for Vietnamese chemical OEMs and contractors.

Why Choose Hindustan Steel Corporation for Vietnam 904L Needs?

We are a trusted exporter of SS 904L plates to leading industries and EPC contractors in Vietnam due to:

  • ISO-certified mill products with full traceability
  • Competitive 904L plate prices (FOB Nhava Sheva / CIF Hai Phong)
  • Fast delivery for shutdown and project orders
  • Multilingual documentation and Vietnamese support
  • Customization for acid tank design and structural layouts

Common Alternatives & Similar Grades to SS 904L

In case of specific cost or design needs, we also supply:

  • SS 316L / 317L – Lower cost, lower corrosion resistance
  • Duplex 2205 (UNS S31803) – Higher strength, moderate acid resistance
  • Alloy 20 (UNS N08020) – For sulfuric acid applications
  • SMO 254 / 6Mo – For extreme pitting environments

However, for long-life, high-acid zones, SS 904L remains the best austenitic option.

Buyer Tip – Which 904L Plate is Right for Your Project?

If you’re a Vietnamese EPC contractor, chemical plant designer, or importer, select your 904L stainless plate based on:

  • Thickness required for pressure vessels or acid-proof tanks
  • Corrosive media – e.g., high chloride, low pH, or oxidizing acids
  • Fabrication technique – whether welding, bending, or forming is involved
  • Temperature range – 904L performs well up to 450°C in acidic zones

Tip: For highest life in sulfuric, nitric, or acetic acid handling – go with solution-annealed 904L with 2B or No.1 finish.
