Mr. Xie is a brand customer for industrial doors, and he needs a lot of strip brush stainless steel every year. Because Mr. Xie’s products are all used in Southeast Asia, where the dampness and seawater are prone to intrusion, the strip brush's gripping parts are rusty, and the stainless steel is the same.

Knowing that Aoqun is a professional strip brush stainless steel manufacturer, Mr. Xie decided to visit Aoqun and seek a solution to the rust problem of strip brush stainless steel. Mr. Aoqun Zhao received Mr. Xie, and through communication, analyzed that the 304 stainless steel used in Mr. Xie’s strip brush stainless steel would have rust for two reasons:

1. The 304 stainless steel used now is not pure material, there are additives, so there will be rust;

2. Due to the special characteristics of the application area, there is seawater backflow, then higher grade stainless steel should be used. Aoqun recommends that Mr. Xie directly replace 316L stainless steel.

Aoqun just had a sample of 316L stainless steel strip brush stainless steel. Mr. Xie can take it to the customer for on-site testing. If there is no problem, use 316L stainless steel to produce. Finally, Mr. Xie took samples of 316L stainless steel strip brush stainless steel to test for rust.

15 days later, Mr. Xie called and said, “I have tried the strip brush stainless steel sample provided to me by Aoqun, and there is no rust. My previous strip brush stainless steel has been corroded by sea water for more than 10 days. It has started to rust a long time ago, so it seems that 316L stainless steel can definitely meet my requirements for using strip brush stainless steel. Thank you for your professional advice."
