Grade 904L stainless steel is a low carbon unstable austenitic stainless steel sheet that the prices of it around the world and among certain manufacturers is interchangeable.
Introduction of Stainless Steel Sheet
Copper is added to this high-alloy stainless steel to increase its resistance to strong reducing acids such as sulfuric acid.
The steel is also resistant to cracking.
Stress corrosion and crevice corrosion resistance Grade 904L is a non-magnetic material with excellent ductility, toughness, and weldability.
Production of 904l stainless steel plate:
904L stainless steel is high-purity steel with low sulfur content.
They can be processed using any standard method.
These qualities can be easily bent to small radii in cold conditions.
It is not post-annealing but should be done at the time of manufacture under severe stress cracking conditions.
Stainless Steel Sheet Qualification
Some of the characteristics of austenitic steel plates are:
- Excellent corrosion resistance.
- They are non-magnetic after annealing.
- When cold working these steels, they harden quickly.
- They cannot be hardened by heat treatment.
- They have high ductility and formability.
- They have excellent soldering ability.
- They are very hygienic and easy to clean.
- They have good performance at high temperatures.
- They have good performance at low temperatures.
- In addition to 304 steel, 316 marine steel plate and 303 machining grade are other common grades of austenitic steel plate.
- Among the 300 series austenitic stainless sheets of steel, the 310 refractory steel plate is the highest priced due to its chemical composition with the highest nickel and chromium content.
The addition of chromium, nickel, molybdenum, and copper elements makes 904L steel perform well in corrosive environments (corrosion resistance).
The Price of Stainless Steel Sheet
The manufacturer's prices and quality Compared to 316L, the addition of molybdenum makes it more resistant to localized corrosion (pitting and crevice corrosion) by chlorides and reducing acids, and especially the addition of copper makes it usable in all concentrations.
sulfuric acid.
Its high alloy content also makes it more resistant to chloride stress cracking, but it is still sensitive.
Its low carbon content makes it resistant to solder sensitization and intergranular corrosion.
904L steel welding
904L steel is easily welded using standard methods.
What You Need to Know about Stainless Steel Sheet
430 and 409 steel sheets are the cheapest steel sheets and are one of the most common ferritic steel sheet grades.
Grade 409 is used in the manufacture of automotive exhausts due to its low cost, corrosion resistance, and excellent formability.
430 steel plate has the largest sales volume among ferritic steels.
By adding nickel to the composition of stainless steel, its microstructure becomes "austenite".
70% of the commercial production of these steels is austenitic.
The most common grade is austenitic plate 304 (1.4301).
More than half of the total stainless steel sales are dedicated to 304 steel.
One of the common names for 304 steel plate is 18/8.
