Frequently Asked Questions

What is 304 HR (Hot Rolled) Stainless Steel Sheet?+
304 HR sheet is a flat-rolled austenitic stainless steel product processed above 1,100°C. It conforms to ASTM A240 / ASME SA-240 Type 304 and comes with a No. 1 mill finish.
What is HR Finish on Stainless Steel Sheet?+
HR finish is the No. 1 finish: hot rolled, annealed, and pickled (HRAP). The surface is rough, matte, and non-reflective. All further finishing starts from this condition.
What is the price of SS 304 HR Sheet per kg?+
In India, the price ranges from ₹145 to ₹225 per kg and $1,600 to $2,100 per metric ton internationally. Final cost depends on thickness, dimensions, finish, quantity, and market conditions.
What is the hardness (HRC) of 304 Stainless Steel Sheet?+
In the annealed state, 304 sheet typically has a hardness of 70–90 HRB, which corresponds to under 20 HRC. Cold working raises the hardness to approximately 40 HRC.
What sizes are available for 304 HR Stainless Steel Sheet?+
Thickness: 3 mm to 100 mm. Widths: 1000 mm, 1250 mm, and 1500 mm. Lengths: 2500 mm to 6000 mm. Custom cut-to-size available.
What is the difference between a 304 HR Sheet and a 304 CR Sheet?+
HR sheet is rolled above recrystallisation temperature with a rough No. 1 finish at a lower cost. CR sheet undergoes additional cold rolling for tighter tolerances and a smooth 2B surface.
Can 304 HR Stainless Steel Sheet be Welded?+
Yes. 304 HR sheet is weldable by TIG, MIG, resistance, and spot welding. For thick multi-pass welds, 304L reduces carbide precipitation risk in the heat-affected zone.
What is the weight of a 304 Stainless Steel Sheet per square foot?+
Weight varies by thickness. At 8.0 g/cm³ density, a 3 mm sheet weighs roughly 2.525 lb/sq ft. Multiply thickness (mm) by 0.842 for lb/sq ft.
