Low carbon 304L stainless steel plate easy to weld good performance
304L stainless steel plate introduction
The "L" in the 304L stainless steel plate stands for Low Carbon. It
reduces the carbon content on the basis of 304 stainless steel, the
general carbon content does not exceed 0.03%, while the carbon
content of ordinary 304 stainless steel is below 0.08%. Due to the
low carbon content, 304L can effectively reduce or avoid the
occurrence of intergranular corrosion when welding or heating in
the temperature range of 450℃ ~ 900℃.
Product performance
Corrosion resistance
It has good corrosion resistance and can resist oxidation,
corrosion and rust in most environments. It has good tolerance to
various media such as acid, alkali, salt, etc., and is widely used
in chemical, food processing, medical and other fields.
Especially in environments containing chloride ions, it shows
better corrosion resistance than ordinary carbon steel and low
alloy steel.
Welding performance
The low carbon content gives it excellent welding performance.
During the welding process, intergranular corrosion and thermal
cracking are not easy to occur, and the strength and corrosion
resistance of the welded joint are comparable to those of the
parent material. This makes 304L stainless steel plate very popular
in the manufacture of various welded structural parts.
Mechanical properties
It has certain strength and hardness, and also has good toughness
and ductility. Its yield strength is about 205MPa, tensile strength
is about 520MPa, and elongation is greater than 40%. These
properties enable 304L stainless steel plate to withstand certain
loads and deformations, and is suitable for the manufacture of
various mechanical parts and structural parts.
Its mechanical properties can be further improved after proper heat
treatment and processing.
Processing performance
Easy to process and form, it can be made into parts and products of
various shapes and sizes through cutting, stamping, bending,
welding and other processing methods.
It has good surface quality and can be polished, brushed and other
surface treatments to give it a beautiful appearance.
Heat resistance
In high temperature environment, 304L stainless steel plate can
still maintain good strength and corrosion resistance. Its maximum
operating temperature can reach about 870℃, which is suitable for
some high temperature working environments.
Application of low-carbon 304L stainless steel plate
Chemical industry:
Used to manufacture equipment such as reactors, storage tanks,
pipelines, etc. Due to its good corrosion resistance, it can resist
various highly corrosive media such as acids, alkalis, and salts,
ensuring the stable operation of equipment and safe storage of
media during chemical production
In the fine chemical industry, it is used to manufacture various
reactors, separators and other small equipment to meet the
production requirements of high precision and high purity.
Petroleum and natural gas field:
In oil extraction, oil pipes, casings, etc. can be made. It can
adapt to the complex environment of underground wells, such as high
temperature, high pressure, and highly corrosive fluids, to ensure
the smooth exploitation of oil and gas resources.
For natural gas transmission pipelines, its good welding
performance and low-temperature toughness can ensure the connection
reliability and safety of pipelines in different environments, and
prevent accidents such as pipeline rupture and
leakage.
Food processing field:
Widely used in food processing equipment, such as food mixers,
conveyors, tanks, etc. Low-carbon 304L stainless steel plate meets
food hygiene standards, is non-toxic and tasteless, and is
corrosion-resistant and easy to clean, which can ensure the hygiene
and safety of the food processing process.
Used to manufacture kitchen utensils, such as sinks, stoves,
tableware, etc. Its beautiful appearance and good corrosion
resistance meet the material requirements of the kitchen
environment.
Medical field:
It can be used to manufacture medical devices, such as surgical
instruments, implants, dental instruments, etc. It has good
biocompatibility and corrosion resistance, will not produce adverse
reactions to human tissues, and can withstand chemical erosion
during disinfection and sterilization.
In the architectural decoration of hospitals, such as walls,
floors, handrails, etc., low-carbon 304L stainless steel plates are
also used to facilitate cleaning and disinfection, and keep the
hospital environment clean and tidy.
Construction field:
It is used for exterior decoration of buildings, such as curtain
walls, roofs, balcony railings, etc. Its beautiful and
corrosion-resistant characteristics not only enhance the appearance
of the building, but also resist the erosion of wind and rain in
the natural environment for a long time.
Inside the building, it can be used to manufacture stair handrails,
doors and windows, bathroom facilities, etc. Provide people with a
safe, comfortable and beautiful living and working environment.
Electronic field:
In the manufacture of electronic equipment, it is used to make
housings, radiators, connectors and other components. It has good
conductivity and heat dissipation, and can effectively prevent
static electricity accumulation and electromagnetic interference,
ensuring the normal operation and stable performance of electronic
equipment.
In the semiconductor manufacturing industry, it can be used to
manufacture parts of wafer processing equipment, such as reaction
chambers, pipelines, etc., to meet the requirements of ultra-clean
environment and high-precision processing.
Automotive field:
Used in automobile exhaust systems, such as exhaust pipes,
catalytic converters, etc. It can withstand the scouring and
corrosion of high-temperature exhaust gas to ensure the long-term
stable operation of the exhaust system.
In terms of automotive interiors, it can be used to manufacture
seat frames, instrument panel brackets, decorative strips and other
parts to provide a beautiful, comfortable and safe internal
environment for the car.
