Baojing Steel supplies high-quality Stainless Steel Hot Rolled Sheets (HR Stainless Steel Sheets) in a wide range of stainless steel grades, thicknesses, widths and surface conditions for heavy-duty industrial and fabrication applications.
Hot rolled stainless steel sheet is produced by rolling stainless steel at elevated temperatures, followed by processes such as annealing, pickling, descaling, leveling and cut-to-length processing. Compared with cold rolled sheets, hot rolled stainless steel sheets are particularly suitable for thicker gauges, structural components, pressure equipment and demanding industrial applications.
We supply austenitic, ferritic, martensitic, duplex, super duplex and heat-resistant stainless steel sheets, with customized dimensions, surface conditions and processing options available according to customer requirements.

No.1 stainless steel sheet is produced through hot rolling, followed by annealing and descaling/pickling. It provides a relatively rough industrial surface and is widely used where appearance is not the primary requirement.
Hot rolled stainless steel sheets are available in a wide range of heavy and medium gauges.
3 mm / 4 mm / 5 mm / 6 mm / 8 mm / 10 mm / 12 mm / 14 mm / 16 mm / 20 mm / 25 mm / 30 mm / 40 mm / 50 mm / Customized

Actual available dimensions depend on the stainless steel grade, thickness, production capability and applicable standard.
Stainless Steel Slab → Slab Heating → Hot Rolling → Annealing → Pickling & Descaling → Leveling → Cut-to-Length → Inspection → Packing
High-quality stainless steel slabs are selected according to:
Grade · Chemical Composition · Thickness · Width · Applicable Standard
Stainless steel slabs are heated to a controlled high temperature to achieve suitable plasticity for hot rolling.
The heated slab passes through rolling mills where its thickness is progressively reduced to the required intermediate or final gauge.
Hot rolling is particularly suitable for the production of thick stainless steel products and large-format industrial materials.
Controlled heat treatment is used to optimize:
Microstructure
Ductility
Toughness
Mechanical properties
Internal stress condition
Oxide scale generated during high-temperature processing is removed through controlled descaling and pickling.
Precision leveling improves the flatness and dimensional stability of the stainless steel sheet.
The hot rolled material is cut according to customer requirements for:
Width × Length
Finished sheets are inspected for:
Chemical Composition · Mechanical Properties · Thickness · Width · Length · Flatness · Surface Quality
The finished sheets are packed using export seaworthy materials and prepared for containerized or other international transportation.
