AISI4140 steel plate is used to make forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, turbocharger transmission gears, pressure vessel gears, rear axles, connecting rods with extremely high loads, and Spring clip. It can also be used for oil deep well drill pipe joints and fishing tools below 2000m, and can be used for molds of bending machines.

Different form P295GH steel pressure vessel, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.

In order to improve the p295gh steel pressure vessel corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main p295gh steel pressure vessel coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking p295gh steel pressure vessel sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.
