Stainless Steel Coil

Description

Stainless steel coil is a product that is processed into a coil by hot rolling or cold rolling. It has the characteristics of high strength, corrosion resistance, high temperature resistance, etc. and is widely used in many industries.
Classification
By material:
Austenitic stainless steel: such as 304, 316, has good corrosion resistance and processing performance.
Ferritic stainless steel: such as 430, has weak corrosion resistance, but low cost.
Martensitic stainless steel: such as 410, has high hardness and good wear resistance.
Duplex stainless steel: such as 2205, has the advantages of both austenite and ferrite, high strength and corrosion resistance.
By surface treatment:
2B surface: smooth and reflective, common in general use.
BA surface: highly bright, often used for decoration.
NO.1 surface: untreated after hot rolling, rough surface.
NO.4 surface: polished, delicate surface.
By thickness:
Thin plate coil: less than 3mm thick, suitable for precision processing.
Medium plate coil: 3-6mm thick, suitable for general industry.
Thick plate coil: Thickness greater than 6mm, suitable for heavy equipment.
Process
Hot rolling: Rolling at high temperature, high production efficiency, but rough surface, often used for thick plates.
Cold rolling: Rolling at room temperature, smooth surface, precise size, suitable for thin plates.
Annealing: Slow cooling after heating to eliminate internal stress and improve performance.
Pickling: Remove the surface oxide layer and improve corrosion resistance.
Polishing: Improve surface finish, suitable for decorative materials.
Features
Corrosion resistance: Chromium elements form an oxide film to prevent further corrosion.
High strength: Suitable for applications with high strength and wear resistance requirements.
High temperature resistance: Some stainless steels still maintain performance at high temperatures.
Easy to process: Good plasticity and toughness, suitable for a variety of processing methods.
Beautiful: Various surface treatments, suitable for decoration and construction.
Uses
Architectural decoration: Used for curtain walls, doors and windows, handrails, etc.
Kitchen equipment: Used for kitchen utensils, tableware, sinks, etc.
Medical equipment: Used for surgical instruments, medical equipment, etc.
Automobile manufacturing: used for exhaust pipes, decorative strips, etc.
Chemical equipment: used for storage tanks, pipelines, reactors, etc.
Electronic appliances: used for electronic components, home appliance housings, etc.
Stainless steel coils have become an indispensable material in modern industry due to their excellent performance and diverse applications.
