Stainless Steel 317 / 317L Instrumentation Fittings Manufacturer

Global Steel is an established manufacturer and supplier of Stainless Steel 317/317L Instrumentation fittings. All products are manufactured using premium quality materials and world-class technology. We provide top-quality products at the best prices due to our extensive knowledge and expertise in the stainless steel industry.

Stainless Steel 316/316L/316H/316Ti Instrumentation Fittings can be customized according to the needs of the customers.

Stainless steel 317 Instrumentation fittings have nickel and chromium in their alloy. They display excellent resistance to oxidation and corrosion. The high amount of molybdenum in its composition gives enhanced resistance to pitting. These instrumentation fittings are more robust and last longer than Stainless Steel 304 Instrumentation Fittings. Stainless Steel 317 Instrumentation Fittings have good tensile and yield strength. They also possess excellent creep-rupture characteristics. These fittings are used in several industrial applications in paper and pulp industries, Textile industries, Chemical equipment, etc.

Stainless Steel 317L Instrumentation Fittings are almost the same as Stainless Steel 317 Instrumentation Fittings, with the exception of having a lower carbon content. They have excellent corrosion resistance and high strength. They are durable and have a long service life if maintained properly. These fittings come in different sizes, dimensions and surface finishes. Stainless Steel 317L Instrumentation Fittings are widely used in many applications in several industries because of their desirable properties. For example marine and chemical applications, Pulp and paper applications, Marine components, Food Processing, Seals and other components for the oil and gas industry. All products undergo a strict quality check process to ensure top quality before dispatch.

Factors to consider when selecting Stainless Steel 317/317L Instrumentation Fittings?

When selecting Stainless Steel 317/317L Instrumentation Fittings, several factors should be considered, including the specific application requirements, such as temperature, pressure, and chemical exposure. The fitting type, such as tube fittings, compression fittings, and ferrule fittings, should also be considered and compatible with other materials in the system. Along with the necessary installation and maintenance methods, considerations for the appropriate size and shape are also important.

Can Stainless Steel 317/317L Instrumentation Fittings be used with other materials?

Yes, Stainless Steel 317/317L Instrumentation Fittings can be used with various other materials, including different stainless steel grades and materials such as copper, brass, and various plastics. The choice of material will depend on the specific application requirements, including temperature, pressure, and chemical exposure, as well as compatibility with the other materials in the system.

What is the difference between SS 317 and 317L Instrumentation Fittings?

The carbon content of Stainless Steel 317 and 317L makes it different them most from one another. Compared to 317L, stainless steel 317 has more carbon, making it more prone to intergranular corrosion and sensitization. While stainless steel 317L is more resistant to intergranular corrosion and sensitization than other varieties of steel due to its lower carbon content than those materials. Hence, when welding or being exposed to high temperatures is required, stainless steel 317L is frequently chosen.
