*5CrMo has high endurance strength and creep strength at high
temperature, good impact toughness at low temperature, good
hardenability, no overheating tendency, small quenching
deformation, acceptable plasticity at cold edge forming and medium
processability. Poor weldability, preheating before welding, post
welding heat treatment and stress relief are generally used after
quenching and tempering, and can also be used after high and medium
frequency surface quenching or quenching and low and medium
temperature tempering.
*4CrMo4 / *5CrMo is used as important structural parts working
under high load, such as transmission parts of vehicles and
engines; The rotor, main shaft and transmission shaft with heavy
load of turbo generator, the large section part *4CrMo4 is used to
manufacture forgings with higher strength and larger quenching and
tempering section than *5CrMo steel, such as large gear for
locomotive traction, booster transmission gear, rear shaft,
connecting rod and spring clamp with great load. *4CrMo4 can also
be used for drill pipe joints and fishing tools in oil deep wells
below ***0m.*4CrMo4 Gas Cylinder Pipe, mainly used in automobile
gas cylinder installation, fire protection, medical fields,
industry equipment, etc.
The carbon equivalent value CEQ of *5CrMo steel is 0.*2%. It can be
seen that the weldability of this material is poor, and its hard
tendency is large during welding. The hot crack and cold crack
tendency of the heat affected zone of *5CrMo alloy pipe will be
large. Especially when welding in the quenched and tempered state,
the cold crack tendency of the heat affected zone will be very
prominent. Therefore, on the basis of selecting appropriate welding
materials and reasonable welding methods, higher pre welding
preheating temperature Under the condition of strict process
measures and proper interpass temperature control, the purpose of
product welding can be achieved.
