ISO 49-1994(E) CL150 AISI 304 Stainless Steel Cast Threaded Bushing
AISI 304 ISO 49-1994(E) CL150 Stainless Steel Cast Threaded Bushing
Product Information
Cast threaded caps are typically made of durable materials such as stainless steel, brass, or other metals to provide strength and corrosion resistance. Stainless steel caps are popular for their excellent corrosion resistance and durability.
Stainless steel cast threaded bushings are ideal for applications where resistance to corrosion and harsh environments is necessary, making them suitable for use in challenging industrial settings.
These fittings are versatile and can be used in a wide range of applications where a reduction in thread size is required, providing flexibility in piping systems.

Benefits of Stainless Steel Casting Screw Fittings
- Stainless steel casting combines good corrosion resistance and high strength, which allows the reduction in wall thickness and weight of pipe fittings. Besides, it can withstand very high flow rates, making it capable to withstand long-term exposure to the elements in almost any environment.
- Cast stainless steel pipe fittings can be used in all types of water, including drinking water in public supply. They have an excellent resistance to the full range of potable waters, including various chloride levels. At the end of its useful life, cast stainless steel is fully recyclable and retains a higher residual scrap value than ordinary cast steel.
- Stainless steel casting of pipe fittings requires low maintenance and does not need an additional coating, in both indoor and outdoor applications. The expected lifetime of a stainless steel pipe fitting is more than 50 years, reducing system down time, replacement and maintenance costs over the life of the installation.
- Last but not the least, stainless steel casting is afforable to produce any type of pipe fittings, and it can produce pipe fittings in both high and small volumes.
