***4PH alloy is a precipitation of
copper, niobium / columbium constituted hardening martensitic
stainless steel. This level has high strength, degree (up to **0º C
/ **2º F) and anti-corrosion properties. After heat treatment, the
mechanical properties of the product more perfect, can reach up to
********0 mpa (******0 ksi) of compressive strength. This level can
not be used above **0º C (**2º F) or under very low temperatures,
its atmosphere and dilute acid or salt has good corrosion
resistance, corrosion resistance and its **4 and **0 the
same.
***4 Precipitation Hardening also known as Type **0 is a
chromium-copper precipitation hardening stainless steel used for
applications requiring high strength and a moderate level of
corrosion resistance. High strength is maintained to approximately
**0 degrees Fahrenheit (**6 degrees Celsius).
General PropertiesAlloy ***4 PH is a precipitation
hardening martensitic stainless steel with Cu and Nb/Cb additions.
The grade combines high strength, hardness (up to **2°F / **0°C),
and corrosion resistance.
Mechanical properties can be optimized with heat treatment. Very
high yield strength up to ********0 MPa (******0 ksi) can be
achieved.
The grade should not be used at temperatures above **2°F (**0°C) or
at very low temperatures. It has adequate resistance to atmospheric
corrosion or in diluted acids or salts where its corrosion
resistance is equivalent to Alloy **4 or **0.

Hot forming
Hot
forming should be treated in a certain temperature range, such as
*******0ºC (********2ºF).
The
whole heat treatment includes solid annealing, cooling( lower than
*5ºC) and
curing.
Cutting
1.
Thermal cutting (plasma, sawing, etc.)
Considering the thermal metamorphism, the cutting
process should be appropriate. After cutting, it needs to be
grinded in order to remove the oxide layer.
2.
Mechanical cutting: shear, punching, cold saw,
etc.
Machining:
Thermoforming
Hot
forming should be carried out within a temperature range *******0ºC
(********2ºF). Complete heat treatment including solution
annealing, cooling (less than *5ºC) and aging (at a given
temperature)

welding:***4 PH alloy can be welded the following:. SMAW,
GTAW, PAW and GMAW preliminary test (to check for cracks and weld
metal toughness), the SAW welding can be carried out. Because
ferrite solidification, reduces the likelihood of weld metal hot
cracking and thermal deterioration. In general, does not require
preheating, intermediate temperature should be controlled at **0 °
C (**8 ° F). After full heat treatment (solution annealing +
hardened), the toughness will increase. Martensitic structure due
to its own characteristics, the weld metal oxygen content is low to
keep the good toughness and ductility. In order to avoid cold
cracking, hydrogen intervention should be avoided. ***4 PH alloy
can be filled with the same type of metal (e.g., E **0 (AWS A5.4)?
ER **0 (AWS A5.9) welding. If welding without taking into account
the mechanical properties of ***4PH to be austenitic filler metal,
then there is no need for heat treatment.
Applications:
• offshore platforms, helicopter
deck, other platforms
• Food Industry
• Pulp and paper industry
• Aerospace (turbine blades)
• Mechanical parts
• Nuclear waste barrel

Corrosion Resistance
***4 PH alloy corrosion resistance is superior to any other
standard hardenable stainless steel. In most cases, its corrosion
resistance is as much as **4. If there exists the risk of stress
corrosion cracking, high curing temperature must be higher than
**0℃.( The best temperature is **0℃. As for Chloride medium,
the best tempering temperature is from **0 ℃ to ***2℃. As for
H2S medium the best tempering temperature is from **0 ℃to ***4
℃. The alloy in the static salty water easily suffers from
polluting corrosion orcracking corrosion.
Machinability
We can treating the ***4 PH alloy under hardening state by way of
solution treatment or quenching water on mechanical processing.
The material hardness changes according to the processing
condition . We usually use high speed cutting tool or carbide
tool after lubrication. to process. If the customer is very
strict with tolerance, we should also consider the changes of the
size during heat treatment.
Welding
Welding measures available : SMAW, GTAW, PAW and
GMAW.After a preliminary test (check the presence
of cracks and the toughness of weld metal), we can use SAW
welding.As a result
of the ferrite curing, it reduces the possibility of a weld metal
cracking and thermal metamorphism. Generally speaking, we do not
need to preheat. The temperature should be controlled
at**0°C (**8°F).After
complete heat treatment (solid annealing + quench hardening),
toughness increases. Due to its martensitic structure
characteristics, low oxygen content in the weld metal keep itself
good toughness andductility. In order
to avoid cold crack, please try to avoid the involvement of
hydrogen.
