16MnDG is a type of Chinese steel that is used for pressure vessels and boilers.

16MnDG is made up of a combination of 16% manganese, 0.8% -1.6% silicon, 0.60% - 0.90% carbon, 0.035% phosphorus, 0.035% sulfur, and less than 0.25% of other elements. The "DG" in the name stands for "low temperature impact resistance," indicating that this steel has been specifically designed to withstand impact at low temperatures.

The chemical composition of 16MnDG may vary slightly depending on the manufacturer or supplier. However, the following are the typical chemical composition ranges:

Note that the exact composition of 16MnDG may vary depending on the specific requirements or standards of the application. It is important to consult the manufacturer or supplier for detailed information about the chemical composition, mechanical properties, and other specifications of this material.

16MnDG steel pipe is a low-temperature steel pipe. 16MnDG steel pipe is suitable for -45℃~195℃ low-temperature pressure vessel pipes and low-temperature heat exchanger pipes. 16MnDG steel pipe has good comprehensive mechanical properties and process properties. The content of phosphorus is slightly lower than that of common 16Mn steel. In addition to the requirement of higher tensile strength and elongation than common 16Mn steel, impact toughness is also required.

【H】 Ceramic lined pipe

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.

【H】 Cast basalt lined steel pipe

Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.

【H】 Ceramic Tile Lined Pipes

Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.

【H】 Rare earth alloy wear-resistant pipe

The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.

【H】 Tubes Erosion Shields

Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.

【H】 ASTM A213 T91 Alloy Tube

The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
