Sliding Flush Bolt Features:

1. High-quality stainless steel material

Stainless Steel Sliding Flush Bolt is made of high-quality stainless steel materials such as SS201, SS304, and SS316. SS201 stainless steel contains 17% - 19% chromium and 4.0% - 6.0% nickel, and has good corrosion resistance and mechanical properties; SS304 stainless steel contains 18% - 20% chromium and 8% - 10.5% nickel, and is a widely used austenitic stainless steel with excellent corrosion resistance, heat resistance and processing properties; SS316 stainless steel contains 16% - 18% chromium, 10% - 14% nickel, and 2% - 3% molybdenum. The addition of molybdenum makes it more corrosion-resistant, especially in chlorine-containing environments. The tensile strength of these materials is between 520 and 620 MPa, and the elongation can reach 40% to 60%, which ensures the strength and toughness of the sliding flush bolt in normal use. It can withstand frequent operations and certain external force impacts in daily use, is not prone to breakage, deformation and other problems, and has a long service life.

2. Diverse surface treatments

Stainless Steel Sliding Flush Bolt undergoes a fine surface treatment process. Common surface treatment methods include SSS (sanded stainless steel color), PSS (polished stainless steel color), PVD (physical vapor deposition), SN (brushed nickel color), CP (brushed chrome color), AB (brushed black bronze color), AC (brushed copper color), PB (brushed bronze bronze color), SB (brushed green bronze color) and customized treatment. Taking PVD surface treatment as an example, its process is to deposit metal or metal compounds on the surface of the bolt under vacuum conditions to form a uniform and dense coating. This coating can not only significantly improve the wear resistance of the bolt, making its surface hardness reach HV1800-2200, but also give the bolt a rich color selection to meet the aesthetic needs of different users and the matching of interior decoration styles. At the same time, these surface treatment processes have passed strict salt spray tests. The bolts treated with SSS and PSS can last for 240-480 hours without rusting under neutral salt spray test conditions, and the bolts treated with PVD can last for 360-600 hours without rusting, which effectively improves the corrosion resistance of the bolt.

3. Precision manufacturing process

After 72 hours, there was no obvious rust on the surface of the SS304 bolt, and there was almost no sign of corrosion on the SS316 bolt. At the same time, the surface-treated bolt has a further improved corrosion resistance. For example, the bolt with PVD surface treatment can last for 360-600 hours without rust in the salt spray test, which can effectively resist the corrosion of water vapor and chemicals in the air, ensure the long-term stable use of the bolt in harsh environments such as humidity and high salt, and reduce the maintenance and replacement costs caused by corrosion.

7. Excellent rust resistance

Stainless Steel Sliding Flush Bolt has excellent rust resistance, which is mainly due to its high-quality stainless steel material and special surface treatment process. The chromium element inside the stainless steel material can react with oxygen in the air to form a dense chromium oxide film, which can effectively isolate the metal matrix from the external environment and prevent the generation and spread of rust. Take SS304 stainless steel as an example. Its chromium content is between 18% and 20%. It can form a uniform, dense and repairable chromium oxide film on the surface. Even if there are slight scratches or damage on the surface of the bolt, this film can automatically repair and prevent further development of rust. In addition, after surface treatment processes such as PVD, a stronger and denser coating is formed on the surface of the bolt. This coating not only has a good decorative effect, but also further enhances the anti-rust performance of the bolt, so that the bolt can maintain a smooth and rust-free surface during long-term use, providing users with high-quality and reliable door lock fixing parts.
