Stainless Hardened Steel Strip:

The stainless steel strip coils and sheets in grades 201, 301, and 304 are widely used across multiple sectors due to their respective performance characteristics:

Stainless Steel Grade 201

● Applications for Strip Coils & Sheets:

● 201 stainless steel, which is relatively more cost-effective, is suitable for applications where moderate corrosion resistance and strength are required but not the highest level.

○ Home Appliances: kitchenware (note that its corrosion resistance is limited in humid environments and it’s not ideal for prolonged contact with water or acidic/alkaline substances).

○ Decorative Materials: architectural decorations, door and window frames, furniture accessories, etc.

○ Base Industrial Products: lower-end hardware components and structural parts that do not come into contact with food or chemical raw materials.

Stainless Steel Grade 301

● Applications for Strip Coils & Sheets:

● 301 stainless steel is known for its high strength and excellent ductility after cold working, with significantly increased tensile strength as deformation increases.

○ Automotive Industry: manufacturing automotive components such as exhaust system parts and fasteners, taking advantage of its good formability and enhanced strength.

○ Electronics and Electrical Industry: production of springs, clips, connectors, and other parts requiring good elastic properties.

○ Structural Components: various mechanical and equipment parts that demand high strength and fatigue resistance.

Stainless Steel Grade 304

● Strip Coil Applications:

● One of the most commonly used austenitic stainless steels, 304 offers excellent corrosion resistance and high mechanical properties.

Food Industry: fabrication of food processing equipment, beverage filling machines, kitchen equipment, due to its superior corrosion resistance and hygiene.

Chemical Industry: creation of chemical equipment, pipes, storage tanks, valves, resistant to a variety of chemical media.

Architectural Decoration: interior and exterior decoration, curtain walls, window and door frames, elevator panels, etc.

Automotive Manufacturing: certain components, particularly those requiring good corrosion resistance in decorative and structural roles.

● Sheet Applications:

Building Structures: water supply systems in high-rise buildings, façade structures, waterproofing layers on roofs, etc.

Medical Devices: surgical instruments, medical equipment housings, and pharmaceutical production machinery.

Engineering Projects: bridges, large-scale infrastructure support structures, etc.

Transportation: vehicle interiors, train and ship decoration and functional components.

In summary, stainless steel strips and sheets in grades 201, 301, and 304 play crucial roles in their respective appropriate application areas. The choice of material depends on specific application conditions, performance requirements, and cost considerations.

Q12.Why Do The Spring Steel Strips Of Rolling Shutters Have Different Shades Of Blue?

The varying shades of blue color of rolling shutter door spring steel strips are caused by differences in surface treatment and material composition during the production process. In industrial products, spring steel strips are often treated with anti-rust treatment or coated with anti-corrosion paint to increase their corrosion resistance and service life. The heat treatment process, temperature, speed, and shielding gas action lead to the color change of the oxide film on the surface of the steel strip, mainly because it can have good strength and anti-rust effectPossible causes of different shades of color include:

Q39.What Are The Effects Of The Content Of Different Chemical Elements On The Physical Or Chemical Properties Of The Steel Strip?

The higher the carbon content, the higher the yield point and the tensile strength, but the lower plasticity and impact properties determine the hardness and toughness of the steel strip. The higher the carbon content, the greater the hardness and the better the oxidation resistance, but the worse the toughness, the easier it is broken.

The higher the Mn content, the better the toughness, plasticity and wear resistance of carbon steel. The increase of manganese content weakens the corrosion resistance of steel and reduces the welding performance.

Cr content can increase the strength and hardness of carbon steel, improve high-temperature mechanical properties, hardenability, corrosion resistance and oxidation resistance

The Ni content increases the strength of the steel while maintaining good plasticity and toughness. Nickel has high corrosion resistance to acids and alkalis, rust and heat resistance at high temperatures.
