Gayatri Tubes are one of the best manufacturer and exporters of SS 446 pipes and also supply all grades of pipes. We are wholesaler of all ferrous and non ferrous material and its product. We manufacturer the stainless steel 446 pipes in all dimensions and diameters as per our customer's requirement. We supply our product in all shapes and sizes with different lengths and thicknesses. Stainless steel is well known as high alloy steel and has excellent corrosion resistance. The grade 446 is non-heat treatable stainless steel and has a ferrite alloy. The alloy stainless steel 446 has many properties like high-temperature strength, heat resistance, resistance to chloride corrosion, etc. In grade 446 have some amount of nitrogen and because of the addition of nitrogen is for grain refinement. The stainless steel 446 alloy can tolerate the temperature range of 815 to 1120 degrees F. the cold working process is too difficult in grade 446 because of its higher chromium content. Other stainless steel grades have easily hardened by cold working rather than grade 446.
The SS 446 pipes available in different types like seamless, welded, polished and electro polished. It is also available in square, rectangular, custom stainless steel pipes. The stainless steel 446 seamless pipes are mainly divided into three groups like martensitic, ferrite and austenitic steel. The stainless steel 446 EFW pipes have a higher amount of chromium and show a good mechanical property. The welded pipes have higher strength and excellent corrosion resistance. The electro polished pipes can be bear up to 871 degrees c and show good resistance quality. The SS 446 pipes have an excellent property like resistance to oxidation, and corrosion. It is also resistance to pitting, chloride and crevice corrosion.
Application of SS 446 pipes- it is used in many industries like chemical and petrochemical company, power generation industry, boiler equipment, heat exchanger, oil and gas refineries, heat treatment, food and beverage process, etc. We conduct various types of testing to check the quality of our product like PMI test, macro and micro test, flaring test, flattening test, chemical test, destructive test, and nondestructive test, etc. We provide packed product of our customer and used packaging in different forms.
