Mo is a customer who specializes in aquarium products. Recently, he has received foreign trade customer inquiries and needs a large number of filter brush for ponds. Because the local water has a very high salt content, the filter brush for ponds purchased before will all rust. It must be replaced at present, and the time is only 10 days. After receiving this order, Mr. Mo was very nervous, and hurriedly find manufacturers.

After listening to the peer introduction of Aoqun, Mr. Mo directly contacted Aoqun Liu. After listening to Mr. Mo ’s feedback, Mr. Liu immediately gave a solution. Mr. Liu said: “If the stainless-steel filter brush for ponds is not used for a long time but get rust, the use environment should be particularly harsh. 304 stainless steel may not meet the local use environment. It is recommended to use 316 stainless steel. 316 is a stainless-steel with better performance than 304, not only corrosion resistance, but It also has better heat resistance and can maintain the original product performance under the harsh environment. We can proof according to the customer's requirements. If it can meet the requirements, we will place an order for production. "Then according to the physical samples provided by Mo, Aoqun immediately made corresponding samples for Mo to give to customers for trial.

By communicating with foreign customers, it was agreed to extend the delivery period. Half a month later, foreign customers reported that the filter brush for ponds using 316 stainless steel as the main material passed the test, and no corrosion phenomenon appeared. Mo always placed orders for 1,000 filter brush for ponds.
