The alloy steel SMA400BW BBN steel surface heat treatment

BBN company team and culture: tt the end of 2019, in order to thank employees for their hard work and enrich their sparetime lives, the company organized a pleasant trip to Phuket Island, Thailand. This tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5o'clock in the afternoon on the 22th December.

Hardfacing wear-resistant steel plate is a kind of wear-resistant steel plate with double-layer structure. In order to make it into wear-resistant parts better, it is necessary to weld and assemble the wear-resistant steel plate, alloy steel SMA400BW. In order to ensure the original comprehensive performance of hardfacing steel plate, the base layer, transition layer and clad layer should be welded respectively. During the welding of hardfacing wear-resistant steel plate, the welding shall be carried out in strict accordance with the drawing, welding process and relevant standards.

The Peru customer has cooperated with us since April 2015, and then they purchased 300 tons A36 mild steel plates as trial order. Since then, they book more than 1000 tons from us every time, and about two times every year. They asked SGS test every time. Through our cooperation those years, we have built very good relationship and they entrust us to buy other related alloy steel SMA400BW products for them from China also. And they have introduced us good customers in Peru, among which there are also governmental projects. It is a win-win cooperation between us.
