Applications


Stainless steel 201 is widely used across industries due to its corrosion resistance, durability, and aesthetic appeal. Key applications include decorative and industrial pipes, architectural fittings (handrails, door handles, stair railings), kitchenware, and furniture. It is also applied in automotive components, consumer electronics, mechanical parts, chemical containers, and food processing equipment. Additionally, its biocompatibility supports medical devices, while its stability makes it suitable for environmental protection equipment such as waste incinerators and wastewater treatment systems.
