Raw Material Selection
The manufacturing process of buttweld fittings begins with the careful selection of raw materials.
Stainless Steel 904L Buttweld Fittings
What is Stainless Steel 904L Buttweld Fittings?
Stainless Steel 904L Buttweld Fittings are components used to connect pipes in a piping system using the buttwelding technique. They are specifically made from Stainless Steel 904L, which is a high-alloy austenitic stainless steel known for its excellent corrosion resistance, especially in harsh environments.
What are the advantages of using Stainless Steel 904L Buttweld fittings?
There are several advantages of using Stainless Steel 904L Buttweld fittings. Firstly, they offer exceptional corrosion resistance in a wide range of corrosive environments, including acidic, chloride-containing, and marine environments. Secondly, Stainless Steel 904L fittings provide excellent durability, high strength, and good weldability, making them suitable for demanding applications.

What is the chemical composition of Stainless Steel 904L Buttweld Pipe fittings?
The chemical composition of Stainless Steel 904L Buttweld Pipe fittings typically includes elements such as chromium (19-23%), nickel (23-28%), molybdenum (4-5%), copper (1-2%), and a low carbon content (maximum 0.02%). These alloying elements contribute to the exceptional corrosion resistance and other properties of Stainless Steel 904L.
What are the key mechanical properties of Stainless Steel 904L Buttweld fittings?
Stainless Steel 904L Buttweld fittings exhibit excellent mechanical properties. They have high tensile strength, which allows them to withstand high pressures and mechanical stress. Additionally, they have good toughness and impact resistance, making them reliable in various operating conditions.
What is the corrosion resistance of Stainless Steel 904L Buttweld fittings?
Stainless Steel 904L Buttweld fittings have outstanding corrosion resistance properties. They offer excellent resistance to general corrosion, including pitting and crevice corrosion, in aggressive environments containing chlorides, sulfuric acid, phosphoric acid, and other corrosive media. Stainless Steel 904L fittings are highly suitable for applications where corrosion resistance is a critical requirement.
Cutting and Shaping
Once the raw materials are selected, they undergo a precise cutting and shaping process.
Heating and Forming
Heating the materials to a specific temperature ensures they become malleable, facilitating the shaping process.
Welding and Joining
These processes ensure secure and leak-proof connections, enhancing the reliability and longevity.
Finishing and Quality Control
After this the buttweld fittings undergo comprehensive finishing and quality control procedures.
Packaging and Delivery
To reach their destination in pristine condition, we employ careful packaging techniques.
