Stainless steel slotted shaft position screws usually refer to steel screws with the ability to resist corrosion by air, water, acid, alkali salt, or other media. Stainless steel slotted shaft position screws are generally not easy to rust, durable, and available for environmental protection equipment, medical equipment, communication equipment, and other fields.
The different alloy compositions, respectively, focus on stainless and acid resistance. Some steels are stainless, but not necessarily acid-resistant, while acid-resistant steels are usually stainless. In people's daily life, often referred stainless steel is also austenitic stainless steel. We use stainless steel slotted shaft fasteners, raw materials are mainly used austenitic 302, 304, 316, and "low nickel" 201, etc.
Stainless steel slotted shaft screws are mainly used for environmental protection equipment, medical equipment, communication equipment, electric power facilities, electronic products, instruments, food machinery, the petrochemical industry, ship assembly, pumps and valves, pipelines, architectural curtain walls, open-air occasions, sports facilities, outdoor decoration, etc.
