Stainless Steel 304L Buttweld Fittings – Designed for Weld Stability and Corrosion Resistance

The 304 is one of the typical grades of austenitic stainless steel; it is a 304L low carbon alloy. The carbon is not overfilled with its content as well as it has a maximum content of 0.03 and this significantly reduces the formation of chromium carbides even during welding. The grain boundary precipitation of carbide could lead to intergranular corrosion particularly in normal stainless steel welded joints.

Reducing the amount of carbon, 304L ensures that its chromium coating is not depleted so that it can maintain its protective coat of oxide. This coating of passive chromium oxide is self-coated on the surface, preventing oxidation, rust, and exposure to mild chemicals of the material.

The high chromium and nickel alloy of about 18-20% and 8-12% give the metal a superior mechanical stability, corrosion strength and flexibility in fabrication. The latter traits make Stainless Steel 304L Buttweld Fittings commonly used in pipelines where integrating the longevity of welding is of high importance.

Besides being corrosion resistant, 304L also has good formability and weldability. It is also not normally subject to post weld heat treatment making it easier to install and allows a project to be less expensive. The material also has a smooth surface finish and this makes it applicable in hygienic and sanitary processing lines.

Comprehensive Range of Stainless Steel 304L Buttweld Fittings

Being the seasoned manufacturers, we offer an entire spectrum of SS 304L Buttweld Fittings, which are used to regulate the changes in the flow direction, transition of diameters, and change of the branch connections in the industrial pipelines. All fittings are designed to have a consistent wall thickness, belevelling and structural integrity.

We have a main product line that is composed of elbows, tees, reducers, stub ends and end caps.

Elbows are made in 45°, 90°, and 180° configurations, giving the user control over the direction of the pipeline direction with the least amount of turbulence and pressure loss. Process systems are provided with tees in equal and reducing type to facilitate connections between branches. Reducers can be concentric or eccentric, to provide easy transitions between pipe sizes to prevent disruption of the flow. Stub ends and end caps offer safe end terminations and compatibility of flanges.

Fittings may be provided on a seamless or welded construction depending on the requirements of the project. Smooth fittings are normally used in high-pressure systems because the fittings are uniformly structured in grain whereas the welded fittings are used in moderate pressure systems because they provide an economical alternative. They also offer custom fabrication in case of project specific design and non-standard dimensions.

Manufacturing Process Focused on Dimensional Accuracy

Precise manufacturing and strict quality control are very important to the performance of Stainless Steel 304L Buttweld Fittings. At Shubham Metals, the process of production starts with certified stainless steel pipes or plates which are obtained after being sourced by approved mills. The chemical verification is done on each batch before forming operations start.

Method of forming depends on size and division of the fitting. Hot forming is normally applied in large diameter and cold forming in smaller parts gives them dimensional accuracy. Unified geometry and wall thickness is guaranteed by hydraulic pressing and controlled shaping methods.

Once formed, fittings are beveled and trimmed to guarantee that there is correct alignment of welding. Surface finishing compositions like pickling and passivation are carried out to eliminate the scale and increase the resistance to corrosion. The individual products are then tested on dimensional inspection, wall thickness check, and visual surface inspection.

Traceability marking is done on all the fittings, such as grade, sizes, heat number and standard specification, and fully documented, meeting international requirements.
