How to use:
- Place the test subject on a flat surface
- Clear the subject
- Put a drop on the tester on to the subject
- Wipe the tester off with tissue
- Check the color changes on the tested spot
201 Stainless Steel
201 stainless steel contains a lower percentage of nickel and chromium, making it more cost-effective but less corrosion-resistant than 201 stainless steel. It is a widely used alloy known for its corrosion resistance, higher tensile strength, and excellent toughness.
Here are key points about it:
- Common Uses: 201 stainless steel is widely used in construction, and manufacturing due to its durability and cost-effectiveness.
- Magnetic Property: Typically exhibit a degree of magnetism due to their microstructure, especially after cold work
- Ways to Identify:
- Laboratory Tests: Conduct tests for hardness, tensile strength, etc. A nitric acid reaction can indicate 201 stainless steel; it shows brown fumigation
- XRF Spectrometer: Delivers accurate results and is commonly employed for elemental analysis in various applications
- Stainless Steel Liquid Tester: The most convenient and cheapest way to find out the of stainless steel includes SS201, SS202, SS301, SS304, SS316. [Click here to buy]

304 Stainless Steel
304 stainless steel is a widely used alloy known for its corrosion resistance and versatility.
Here are key points about it:
- Common Uses: 304 stainless steel is widely used in kitchen appliances, construction, and manufacturing due to its durability and ease of fabrication
- Magnetic Property: Typically exhibit a degree of magnetism due to their microstructure, especially after cold work
- Ways to Identify:
- Laboratory Tests: Conduct tests for hardness, tensile strength, etc. A nitric acid reaction can indicate 304 stainless steel; it shows brown fumigation
- XRF Spectrometer: Delivers accurate results and is commonly employed for elemental analysis in various applications
- Stainless Steel Liquid Tester: The most convenient and cheapest way to find out the of stainless steel includes SS201, SS202, SS301, SS304, SS316. [Click here to buy]
