Qingdao O.B.T Co., Ltd. shone at the 2023 GIFA/NEWCAST/METEC/THERMPROCESS international casting exhibition in Dusseldorf, Germany. The company specializes in gas and steam turbine components, highlighting materials like titanium and high-temperature alloys. Exciting talks with global clients were a major highlight.

Qingdao O.B.T. proudly welcomes our Russian partners, who recently visited our facilities. This successful collaboration enhances our presence in the field of high-temperature alloys and titanium, solidifying our commitment to global excellence.

DZ22B alloy is a high-strength directionally solidified nickel-based superalloy with excellent high-temperature strength and medium-temperature properties.

General CNC processing generally refers to precision machining, CNC processing lathes, CNC processing milling machines, CNC processing boring and milling machines, etc.

High temperature alloys or high performance alloys are alloys that exhibit excellent mechanical strength and creep resistance at high temperatures, good surface stability, and resistance to corrosion and oxidation. They usually have an austenite-centered cubic crystal structure containing nickel, cobalt or nickel-iron alloy elements. The development of superalloys has been driven primarily by the aerospace and power industries.

NS315 is a nickel-based corrosion-resistant alloy with excellent corrosion resistance and mechanical strength at high temperatures. It is widely used in chemical industry, energy, aerospace and other fields. The alloy has a high chromium content, which can effectively resist oxidation and corrosion, and also contains appropriate amounts of nickel and iron elements, which enhance the alloy's toughness and heat resistance.
