Melting and Refining
The core manufacturing process kicks off with melting raw materials in high-capacity furnaces:
– Electric Arc Furnace (EAF): Predominantly used for stainless steel and alloy steel due to precise temperature and composition control.
– Basic Oxygen Furnace (BOF): Often used for carbon steel variants.
This phase may include decarbonization and controlled addition of alloying elements. Advanced refining (e.g., argon-oxygen decarburization, AOD) removes impurities and adjusts carbon, sulfur, and gas content.
Key Considerations for Buyers:
– Buyers should confirm that suppliers operate modern, efficient furnaces and follow emissions regulations—important for buyers under strict environmental requirements (e.g., EU imports).
– Ask for traceability in materials and process logs for accountability.
Casting and Forming
Once molten, the steel transitions into the solid phase:
– Continuous Casting: Produces billets, blooms, or slabs, which will be further processed.
– Hot Forming (Rolling): Rollers or presses shape steel at high temperatures (e.g., hot-rolled coils, bars).
– Cold Forming: Cold rolling or drawing improves surface finish and tightens dimensional tolerances for sheet, wire, and tube products.
For specialty stainless steels, forming processes must tightly control temperature profiles and cooling rates to maximize properties.
Actions for Buyers:
– Specify desired grades and tolerances upfront; reputable suppliers will provide rolling schedules and records.
– For critical applications (e.g., pressure vessels), ensure forming processes meet relevant codes (such as EN or ASTM).
Heat Treatment, Cutting, and Surface Finishing
Post-forming, heat treatments (such as annealing, quenching, or tempering) are used to achieve the target mechanical properties.
– Descaling: Removes oxide layers formed during hot processing, often using acid pickling.
– Cutting: Precision shears, lasers, or water-jet systems cut material to size.
– Surface Finishing: Includes polishing, passivation, or coating, tailored to the application’s corrosion and aesthetic needs.
Custom finishes—mirror, brushed, or matte—are common for architectural or food-grade end users, while industrial buyers may require specific passivation standards.
Critical Buyer Steps:
– Define required surface finish and passivation specifications.
– Request samples or proof-of-process to confirm finished surface quality.
