Product Introduction
AISI Hot Rolled Stainless Steel Sheet is an industrial-grade flat metal product manufactured through high-temperature rolling processes, engineered to deliver exceptional mechanical strength, structural integrity, and long-term corrosion resistance. Designed to withstand severe operating environments, these sheets serve as foundational structural and containment materials across heavy industries, chemical processing plants, and energy infrastructure.
Available across a comprehensive portfolio of austenitic, ferritic, martensitic, and duplex alloy grades, our hot rolled plates provide reliable performance under high thermal stress and corrosive attack. Strict metallurgical control from raw material selection to final hot rolling, annealing, and pickling ensures consistent thickness tolerance, uniform microstructures, and superior weldability for global manufacturing and engineering projects.

Surface Finish Options & Processing Capabilities
No.1 Finish: Hot-rolled, annealed, and chemically descaled (acid pickled) to produce a dull, textured grey surface. Ideal for industrial applications where surface reflectivity is not critical.
2D Finish: Smooth, non-reflective matte finish produced by cold rolling followed by annealing and pickling.
BA (Bright Annealed) Finish: Controlled atmosphere heat-treated surface retaining a bright, reflective appearance.
Value-Added Processing: Advanced precision services including plasma cutting, laser cutting, waterjet cutting, beveling, surface wire-drawing, protective film coating, and custom leveling to exact drawing specifications.
Manufacturing & Quality Control
Production begins with premium raw material sourcing and electric arc furnace melting followed by ladle refining and continuous slab casting. Hot rolling is executed under strictly monitored thermal profiles to achieve refined grain structures and accurate dimensional profiles. Subsequent heat treatment, mechanical leveling, and acid pickling eliminate internal stresses and surface scale.
Comprehensive quality verification protocols are integrated at every stage of production. Testing regimens encompass optical emission spectrometer chemical analysis, tensile and elongation mechanical testing, Brinell hardness testing, ultrasonic internal defect inspection, and strict micrometer gauge thickness verification. Every outgoing shipment is accompanied by a certified Mill Test Certificate in compliance with EN 10204 3.1.
Industry Applications
Chemical & Petrochemical Processing: Fabrication of heavy-duty reaction vessels, chemical storage tanks, acid transport pipelines, distillation towers, and scrubber units.
Energy & Power Generation: Manufacturing of heat exchanger tubing plates, flue gas ducts, boiler components, and renewable energy structural frameworks.
Heavy Machinery & Pressure Equipment: Construction of industrial press frames, structural base plates, mining machinery components, and certified pressure vessels.
Architecture & Infrastructure: Structural load-bearing members, bridge expansion plates, marine pier reinforcement, and architectural cladding panels.
Food, Beverage & Pharmaceutical Industry: Heavy-duty processing vats, mixing tanks, sanitary sterilization chambers, and bulk material handling systems.
