What is 201 stainless steel ?
201 stainless steel holds an important position in the stainless steel market due to its excellent cost performance and good processing performance. Aoxing is a professional supplier of stainless steel materials. We are committed to providing overseas customers with high-quality 201 stainless steel products, including stainless steel plates, stainless steel coils, stainless steel pipes, etc. This article mainly provides a detailed introduction to the composition, classification and application of 201 stainless steel, helping customers choose the products that best meet their own needs.
The Chemical Composition Of 201 stainless steel
| Element | Content（%) | Function |
| Cr | 16.0-18.0 | Improve corrosion resistance and form a passivation film |
| Ni | 3.5-5.5 | Enhance toughness and improve corrosion resistance |
| Mn | 5.5-7.5 | Replace part of the nickel to reduce costs |
| C | ≤0.15 | Affects hardness and weldability |
| N | ≤0.25 | Improve strength and stabilize Austenite structure |
| Cu | 0.5-2.0 | Improved cold working properties |
Different Grade of 201 Stainless Steel
In the early years, we often distinguished 201 steel grades with high copper (J4) and mid-copper (J1), but with the development of lower copper content, there was born J3 instead of J1; then, J2 and J5 instead of J3.
Copper content: J4>J1>J3>J2>J5.
Carbon content: J5>J2>J3>J1>J4.
Hardness arrangement: J5, J2>J3>J1>J4.
The order of prices from high to low is: J4>J1>J3>J2, J5.
J1: The carbon content is slightly higher than J4 and the copper content is lower than J4. Its processing performance is less than J4, and suitable for ordinary shallow drawing, such as decorative boards,sanitary products, sinks, product tubes, etc.
J2/J5: Simple ornament tubes are still good, because the hardness is high and the polishing result is more beautiful, but for the square tube or the curved tube (90°) is prone to breaking open.. Due to the high hardness, the flat sheet surface is more beautiful, and the surface treatment such as No.4, polishing and plating is no problem. But the biggest problem is the bending, it’s very easy to break when bending ,and the groove is easy to break open.
J3: Suitable for ornament tubes. Simple processing on the decorative panel, but it’s not possible with a little difficult processing. There is feedback that the material was found an inner seam after bending and breaking .
J4: It’s a higher-end J series, which is suitable for deep drawing products especially the requirement of salt spray test. For example, sinks, kitchen utensils, bathroom products, water bottles, vacuum flasks, door hinges, pots, etc.
The Main Application Of 201 Stainless Steel
1.Construction and decoration
201 stainless steel is often used for interior and exterior decoration of buildings. Due to its beauty, corrosion resistance and relatively low cost, it is suitable for:
Interior decoration: stair railings, door frames, skirting boards, elevator decorative panels
Outdoor structures: billboards, road signs, curtain wall frames, guardrails
Public facilities: bus stops, bus shelters, urban sculptures, etc
Advantages: The surface is easy to polish and can be colored (such as rose gold, black titanium) to enhance the decorative effect
2.Home furnishings and kitchenware
201 stainless steel is widely used in the home furnishing industry, but it should be noted that its corrosion resistance is not as good as that of 304 stainless steel, so it is mostly used in non-food direct contact scenarios:
Kitchen ware: cutlery rack, storage rack, sink (some low-end products)
Furniture accessories: table and chair legs, cabinet handles, bathroom brackets .
Household appliances: microwave oven stand, oven inner liner, refrigerator outer shell (some economical products)
Restrictions: Not recommended for use in food-grade containers (such as the inner liner of thermos flasks), as long-term contact with acidic liquids may cause manganese to precipitate
3.Industry and Manufacturing
201 stainless steel is mainly used in the industrial field for structural components and parts with low requirements for corrosion resistance.
Automobile manufacturing: exhaust pipes, body trim strips, door trim strips
Chemical equipment: storage tanks, pipelines (in non-strong acid and strong alkali environments.
Mechanical parts: metal stamping parts, fasteners, bearing brackets
Advantages: Good processing performance, suitable for stamping, welding, bending and other processes, with a cost lower than that of 304 stainless steel
Conclusion
201 stainless steel, with its economy and applicability, has become the ideal choice for multiple industries such as construction, home furnishing and industry. Our company offers a variety of 201 stainless steel products in different specifications and can also carry out customized processing according to customer requirements.If you need further information or purchase, please feel free to contact us at any time.
