We Navgraha Steel & Engg Company fabricate SS 309/SS 309H Fitttings and supply extended industrial applications. These SS 309 Fitttings are used for many functions in various systems. These pipe fitting has high demand in the domestic and international market due to its versatility and other properties. We offer these Fitttings in different sizes and thicknesses. Using these Fitttings gives all applications smoothly working and makes a smooth flow of liquid from one place to another. Therefore, Fitttings are more important in the pipeline.
These Fitttings are used in a piping system to change the direction which is joined mechanically. We finish these fittings using international standards also. We offer these SS 309H Fitttings in various forms and sizes as per application demand. These stainless-steel grades are used in applications where high temperature is required.
The SS 309H chemical composition:
These Fitttings are made from material grade SS 309H containing Iron, Chromium, Nickel, Manganese, silicon, and carbon. It also contains phosphorous and sulfur. Because of this chromium content, these fittings show high resistance to corrosion.
Some Benefits of these SS 309/SS 309H Fitttings are the following:
• Outstanding resistance to oxidation
• Soaring temperature Potency
• Creep Resistance
• Good strength at high pressure
• Excellent resistance to heat
• Provides good resistance to creep deformation
These pipe fitting shows mechanical properties at typical room temperature like tensile strength, yield strength, elongation at break, hardness, and Elastic Modulus. These fittings are also well-known for their thermal properties, like the thermal expansion of co-efficient and thermal conductivity. Fittings have high electrical resistivity, density, and melting point. This stainless steel alloy 309 can be used in slightly oxidizing, nitriding, cementing, and thermal cycling applications. Whereas the high service temperature must be reduced. In the annealing process, the ductility is increased. SS 309 Fitttings hardness and strength is enhanced to a higher value with the cold working process. We provide these Fitttings has ability to stay at high temperatures without any damage. These fittings are not affected by moist environments. This alloy is easily fabricated. We produce these fittings are found in various industries for special applications.
These fittings are used in the following industries:
• Oil Mills
