Ningbo port has initially formed an all-round three-dimensional collection and distribution network of expressways, railways, aviation, river sea intermodal transport, water to water transfer, etc.

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. p235gh chemical composition Heat treatment process refers to the ability to change the microstructure and properties of p235gh chemical composition after heat treatment, including hardenability, hardenability, temper brittleness, etc.

20G steel is a common carbon steel used to manufacture boilers. The performance of 20G steel is basically the same as that of 20# steel. The requirements for impact toughness, strain aging impact value and cold bending of 20G steel are increased. The yield ratio of 20G steel is slightly higher, and certain fatigue and corrosion resistance are required for p235gh chemical composition steel to ensure the safe operation of boilers. 20G steel is suitable for manufacturing marine boilers, steam boilers and other boiler accessories with pressure less than 6Mpa and wall temperature less than 450 ℃.
