This product is a nipple pipe fitting manufactured using AISI 321/321H Stainless Steel, which is ButtWelded. This particular kind of pipe fitting is manufactured from premium grade stainless steel, which is used to join two pipes with the same diameter. Butt-welded construction ensures a high level of strength and lack of leakage between the pipes. The fitting incorporates a nipple shaped such that pipes can be installed and removed easily. The material AISI 321/321H stainless steel used in this pipe fitting is a high standard that provides good corrosion resistance, stability, and strength. It is very much applicable in various uses, such as chemical processing and food and beverages manufacturing industry which includes oil and gas exploration. The quality of products we provide at Rexon Pipe Fitting is something that we take great pride in. Our AISI 321/321H Stainless Steel ButtWelded Nipple Pipe Fitting is made to meet the highest standards, and is subjected to stringent quality control tests to ensure that it meets our customers’ demands.
The AISI 321/321H Stainless Steel ButtWelded Nipple Pipe Fitting is a pipe fitting made of high-quality materials and meant that it offers a tight, non-leaky connection between two pipes with the same diameter. In addition, it is a stainless steel material used for various purposes.
A Buttweld Stainless Steel Welded Nipple Pipe Fitting is a short piece of pipe with a beveled or plain end on one side and a male threaded end on the other, used to connect pipes and flanges.
A Buttweld Stainless Steel Barrel Nipple Pipe Fitting is a short piece of pipe with a beveled or plain end on one side and a male threaded end on the other, used to connect pipes and flanges.

The Buttweld Stainless Steel Nipple Pipe Fittings physical property is affected by the selection of stainless steel type and grade depending on mechanical features along with resistance to media.
| Property | Typical Values and Description |
|---|---|
| Melting Point | 1,371°C (2,500°F) to 1,483°C (2,701°F), depending on grade |
| Magnetic Properties | Austenitic stainless steels are typically non-magnetic, while ferritic and martensitic stainless steels can be magnetic |
| Tensile Strength | Ranges from 500 MPa to 2,000 MPa or more, depending on the grade |
| Yield Strength | Typically ranges from 200 MPa to 1,000 MPa or more, depending on the grade |
| Hardness | Measured on the Rockwell hardness scale (HRC or HRB) or the Brinell hardness scale (HB), dependent on alloy and heat treatment |
| Corrosion Resistance | Known for exceptional corrosion resistance, suitable for use in corrosive environments |
| Machinability | Varies by grade, some grades are more challenging to machine than others |
| Weldability | Generally weldable, welding procedures and filler materials influence weld quality and corrosion resistance |
| Ductility | Stainless steel is often ductile, meaning it can be stretched or bent without breaking |
| Toughness | Exhibits good toughness, absorbing energy without fracturing |
But despite this, Buttweld Stainless Steel Nipple Pipe Fittings are produced from various grades of stainless steel that provide high chemical and corrosion resistance based on the environment.
