The Stainless Steel Hard and Half Hard Coils primarily consist of austenitic stainless steel, usually grades 304 or 316, with chromium, nickel, and iron being the main components. The Hard coils undergo cold working to boost their hardness and tensile strength, while the Half Hard coils maintain a balance of moderate strength and enhanced formability. Both variants showcase outstanding corrosion resistance, toughness, and wear resistance. The Hard coils are perfect for high-stress situations, while the Half Hard coils provide flexibility and ease of fabrication. These mechanical characteristics make them ideal for applications that demand strength, durability, and stability.
Hot rolled hard/half hard coils are available in thicknesses ranging from 1.2mm to 10mm and widths up to 2000mm. These coils offer moderate corrosion resistance, making them suitable for structural and automotive applications. A rough surface finish and high strength characterize them.
Cold rolled hard/half-hard coils come in thicknesses from 0.3mm to 6mm and widths up to 1500mm. These coils provide excellent corrosion resistance and a smooth surface finish, ideal for precision and aesthetics applications. They are commonly used in manufacturing appliances and automotive parts.
Polished hard/half-hard coils are available in thicknesses from 0.5mm to 3mm and widths up to 1500mm. These coils offer high corrosion resistance and a superior polished finish, making them suitable for decorative applications and high-visibility components. They are often used in architectural and kitchen equipment.
HR hard/half hard coil sheets are available in sizes ranging from 2mm to 10mm in thickness and up to 2000mm in width. These sheets provide moderate corrosion resistance and are suitable for heavy-duty applications requiring robust materials. They are used in construction, shipbuilding, and industrial machinery.
CR hard/half-hard coil sheets come in thicknesses from 0.4mm to 6mm and widths up to 1500mm. These sheets offer excellent corrosion resistance and a smooth surface finish, which is ideal for precision and cleanliness applications. They are used in the production of medical instruments and food processing equipment.
Finished hard/half-hard coil sheets are available in thicknesses from 0.5mm to 5mm and widths up to 1500mm. These sheets provide high corrosion resistance and an aesthetically pleasing finish, making them suitable for end-use applications without further processing. They are used in the manufacture of consumer electronics and home appliances.
