Hot Rolled Stainless Steel Coil
Product Definition
Hot Rolled Stainless Steel Coil is produced by rolling stainless steel slabs at temperatures above the recrystallization range, resulting in a stable metallurgical structure and reliable mechanical properties for industrial fabrication.
This material is used in structural and heavy-duty engineering applications where consistency, durability, and long-term supply stability are required in procurement decisions.
Typical applications include construction engineering, petrochemical systems, energy equipment, shipbuilding, industrial machinery, and heavy fabrication industries.
Manufacturing System
Our production system is based on an integrated furnace-controlled manufacturing process:
- Continuous casting → hot rolling production line
- Furnace-based heat number batch control system
- Multi-line rolling capacity for industrial production
- Controlled cooling after hot rolling
- Industrial coil finishing and inspection process
- Annual production capacity: 50,000 tons
Production Control Logic
Each coil is produced under a furnace heat number. All coils within the same heat share identical chemical composition range and are tracked throughout production, inspection, and shipment.
