1. Core characteristics
Chemical and physical properties
Composition characteristics: Carbon content ≤ 0.15%, chromium 16-18%, nickel 3.5-5.5%, manganese 5.5-7.5%, national standard model 1Cr17Mn6Ni5N.
Corrosion resistance: It has basic acid and alkali resistance and is suitable for dry and clean environments, but it is easy to rust in strong oxidizing acids (such as nitric acid) or long-term humid environments.
Mechanical properties: Tensile strength ≥ 520MPa, hardness up to 180HB, high density makes it suitable for thin plate processing.
Processing and surface treatment
Excellent cold/hot processing performance, supports cutting, bending, stamping, welding and other processes, and the surface is smooth and bubble-free after annealing.
Surface treatment methods are diverse, including 2B glossy, brushed, frosted and color coating (such as elevator door panels, decorative curtain walls).
Economic advantage
Low nickel content, significantly lower cost than 304 stainless steel, with more prominent price advantages in North China.
2. Typical application areas
Architectural decoration
Indoor scenes: elevator door panels, handrails, cabinet countertops, taking advantage of their high finish and wear resistance.
Outdoor scenes: bus stops, subway signboards, which require regular maintenance to avoid corrosion.
Industrial manufacturing
Light industrial products: watch cases, watch strap bottom covers, shallow stretch containers (such as tableware, lighting accessories).
Equipment parts: food processing conveyor belts, non-critical chemical pipeline brackets, suitable for low-corrosion environments.
Transportation and home
Automobile/train interior decoration parts, furniture metal frames (table and chair legs, wardrobe handles).
Kitchen sinks and stove panels should avoid long-term contact with strong acid cleaners.
3. Use restrictions and precautions
Environmental restrictions: Anti-rust coating or more corrosion-resistant materials (such as 304 stainless steel) are required in high humidity and coastal areas.
Maintenance requirements: Colored coated products should be protected from scratches by hard objects and cleaned regularly to maintain their gloss.
Alternatives: If the budget is sufficient in municipal projects, it is recommended to give priority to 202 stainless steel with better corrosion resistance.
The above content combines the performance parameters, economic value and industry adaptability of 201 stainless steel plates, which can meet the basic needs of decoration, light industry and other fields.
