Shop Alloy 28 Hot Rolled (HR) Sheet, Alloy 28 Cold Rolled (CR) Sheet, and 2mm Alloy 28 Sheet – Built for Durability
Nandini Steel supplies Alloy 28 Sheet to industries running acid recovery units, phosphoric acid plants, and pickling lines across India. Twenty-five years in the alloy trade means our stock room holds thicknesses and finishes most stockists order on request. Every sheet ships with a mill test certificate, verifying chemistry before the material reaches a weld bay.
Alloy 28 Sheet Manufacturer: Hot Rolled, Cold Rolled & Custom
Key Features of Alloy 28 Sheet
- Improved Corrosion Resistance:Although SS 904L is good in chloride and sulfuric acid conditions, Alloy 28 is superior to it in extremely aggressive conditions such as phosphoric and nitric acids because of its increased chromium and molybdenum content.
- Greater Stress Corrosion Cracking Resistance: Alloy 28 offers superior resistance to stress corrosion cracking in chloride-containing solutions compared to SS 904L thereby being more dependable for offshore and marine environments.
- Wider Temperature Range: Alloy 28 offers stability at both higher and lower temperatures compared to 904L which is more sensitive to temperature fluctuations in certain corrosive environments.
- Higher Mechanical Strength:Alloy 28 has better tensile and yield strength than 904L making it the preferred choice in pressure vessels, heat exchangers, and other high-stress environments.
- Better Versatility in Harsh Media: Unlike 904L, which is mostly recommended for sulfuric acid service, Alloy 28 is suitable for a broader range of chemicals, including acidic and alkaline solutions, giving it an edge in multi-purpose applications.
Compositions and Properties of Alloy 28 Sheet
Alloy 28 Sheet carries 31-32% Nickel, 26-28% Chromium, 3-4% Molybdenum, and 1-1.5% Copper, with Iron making up the balance alongside trace manganese, silicon, Phosphorus, Sulfur, and Carbon. Nickel and molybdenum block pitting and crevice attack in chloride-heavy streams. Copper handles the harder job of resisting reducing acids like sulfuric acid above 40% concentration, a condition that destroys standard austenitic grades within months.
Chromium adds oxidizing-side protection, which matters in mixed-acid environments where a sheet faces both oxidizing and reducing conditions in the same vessel. Sulfuric, phosphoric, and nitric acid service all fall within the working range of this alloy steel sheet. Our stock covers Alloy 28 Hot Rolled Sheet for heavier gauges and cold-rolled finishes for tighter surface tolerance. We also carry Alloy 28 Shim Sheets for gasket and spacer work and Alloy 28 Strip in coil form for continuous processing lines.
Manufacturing Process & Quality Assurance
Our sourcing partners melt Alloy 28 by vacuum induction or electric arc furnace processes and then hot roll and, if needed, cold roll to final gauge. Annealing and pickling remove internal stress and the scale from the surface. Every batch is checked against ASTM B463 for chemistry and mechanical properties, and we run positive material identification on incoming stock to catch mix-ups early.
Industrial Applications of Alloy 28 Sheet
Chemical plants specify Alloy 28 Sheet wherever sulfuric or phosphoric acid handling exceeds the limits of standard stainless grades.
- Phosphoric acid production, where reactor linings and tubesheets face constant acid exposure at elevated temperatures
- Sulfuric acid pickling lines in steel mills, handling spent acid recovery at concentrations that destroy lesser alloys
- Flue gas desulfurization units, where absorber internals face acidic condensate mixed with chloride ions
- Pulp and paper bleaching equipment, exposed to chlorine dioxide and acidic bleach liquors during production runs
- Pharmaceutical reactor vessels, requiring corrosion resistance with low metal-ion leaching into sensitive batches
Packaging, Testing & Delivery Certifications
We ensure that every Alloy 28 sheet undergoes mechanical and chemical analysis, ultrasonic testing, and PMI testing before dispatch. Sheets leave our facility packed in wooden crates with plastic wrapping and edge protectors, a combination that has held up through export shipments to the Middle East and Southeast Asia without damage claims. Our ISO 9001:2015 certification covers the supply chain end to end.
Mill test certificates travel with every shipment as standard practice, not an add-on. Third-party inspection reports from SGS or Bureau Veritas are available on request and are arranged before the sheet leaves our warehouse.

Latest Price List of Alloy 28 Sheets
Pricing for Alloy 28 Sheet moves with LME nickel and molybdenum indices, since these two elements make up nearly 35% of the alloy’s composition by weight. Thickness, surface finish, order quantity, and certification level (standard mill certs versus third-party inspection) shift the final quote too. A 3mm hot-rolled sheet in bulk prices differently from a 0.5mm shim sheet cut to custom dimensions, even from the same heat.
We publish current rates only against a specific requirement, since a fixed number here would be outdated within days of nickel price movement. Send us your requirements for thickness, finish, and quantity, and our team returns a quote reflecting today’s raw material rates.
Why Choose Nandini Steel as Your Alloy 28 Sheet Manufacturer?
Twenty-five years of stocking nickel and stainless alloys have taught us where supply chains break down, and we build our operation around avoiding those points.
