1. If acid and alkaline substances are left on the surface of the stainless steel knob, chemical reactions will occur, causing local corrosion, so we should try to avoid alkali and salt substances when using the knob.

2. Secondly, some organic matter juices will form organic acids when they meet the stainless steel knob, so the metal surface of the knob will also corrode in a long time.

3. Some polluted air contains a large amount of sulfide, nitrogen oxide and other gases, so it is easy to cause chemical corrosion.

4. If there are other metal residues on the surface of the knob, if it encounters humid air, it will produce some chemical reactions, which will damage the protective film of the knob.

T52-nut type locking knob

Using SUS304 material

Stainless steel has corrosion resistance, under special hygienic, climatic and environmental conditions or in environments where corrosion-resistant materials are required by law

Uses: chemical industry, food, equipment and testing instruments
