200 series stainless steel is chromium-manganese-nickel alloy, mainly with manganese and nitrogen to replace part of the nickel, so as to obtain good mechanical properties and corrosion resistance, while the price is relatively affordable, often as a cheap substitute for 300 series stainless steel.
201 Stainless steel (1Cr17Mn6Ni5N SUS201)
Characteristics: It has the characteristics of acid and alkali resistance, high density, no bubbles and no pinholes after polishing.
Uses: Mainly used in the production of decorative pipes, industrial pipes and some shallow stretching products, such as decorative plates and hardware products.
202 Stainless steel (1Cr18Mn8Ni5N SUS202)
Properties: By replacing part of nickel with manganese and nitrogen, good mechanical properties and corrosion resistance are obtained. Its room temperature strength is higher than 304 stainless steel, and it has better oxidation resistance and medium temperature strength below 800℃.
Uses: Mainly used in the production of decorative pipes, industrial pipes, decorative plates and some shallow stretching products.
2205 Stainless steel (00Cr22Ni5Mo3N SUS2205)
Features: The content range of chromium, molybdenum and nitrogen elements is narrow, and it is easy to achieve a relative balance, thereby improving the strength, corrosion resistance and welding performance of the steel.
Uses: It is mainly used for materials with high performance requirements and need to be welded, such as oil and gas pipelines, etc., and is also used for heat exchangers and cold shower devices that are resistant to seawater and high temperature concentrated nitric acid in oil refining, fertilizer, paper making, petroleum, chemical and other industries.
Physical and mechanical properties
Density: The density of stainless steel material usually varies depending on its specific composition and manufacturing process, but 202 stainless steel strip as austenitic stainless steel, its density is roughly similar to 300 series stainless steel.
Tensile strength: ≥520MPa (some data may give slightly different values, but usually within this range).
Yield strength: conditional yield strength ≥275MPa, yield strength (yield stress) is 350N/m㎡.
Elongation: ≥40%.
Section shrinkage: ≥45%.
Hardness: HV280°~420° (HV±20°).
Characteristics and applications
Features:
Corrosion resistance: Although the corrosion resistance of the 200 series stainless steel is usually lower than that of the 300 and 400 series, the 202 stainless steel strip still has some corrosion resistance and is suitable for a variety of environments.
High temperature performance: Due to the high phase change temperature of austenitic stainless steel, 202 stainless steel strip has good high temperature resistance and does not change the metallographic structure at 350 ° C.
Mechanical properties: with high strength and good ductility, suitable for a variety of processing and forming processes.
Applications:
Architectural decoration: such as interior and exterior decoration, railings and so on.
Hotel facilities: such as kitchen equipment, tableware, etc.
Shopping mall decoration: such as shelves, display cases, etc.
Others: It can also be used to make glass railing parts, stainless steel straps, clamps, brackets and cable ties.
