Sachiya Steel International is one of the Leading Manufacturer And Exporter of Stainless Steel 446 Buttweld Fittings, which have good resistance to oxidation at temperatures up to 1700 Degree F. Our Stainless Steel 446 Elbow Pipe Fittings is a non – magnetic stainless steel, which is not harden able by heat treatment. These Stainless Steel 446 Reducer is the free machining modification of the basic 18 % chromium – 8 % nickel stainless steel. In extreme oxidizing atmospheres of our Stainless Steel 446 Tee Pipe Fittings, irregular scaling may be encountered, particularly above 1400 Degree F.

These Stainless Steel 446 Cross Pipe Fittings is molybdenum containing austenitic stainless steel, with improved corrosion resistance over other alloys. The increased levels of chromium, nickel and molybdenum over our Stainless Steel 446 Bend improve chloride pitting resistance and general corrosion. Through the controlled addition of nitrogen it is common for SS 317L to meet the mechanical properties of these Stainless Steel 446 Stub End Pipe Fittings, while maintaining a low carbon content.

Our Stainless Steel 446 End Cap Pipe Fittings is a high – carbon martensitic stainless steel, where as a martensitic stainless steel, it is magnetic and can be hardened by heat treatment. The high carbon content in these Stainless Steel 446 Dish Cap provides high hardness and strength, where despite this carbon content, the chromium content is sufficient to retain its stainless characteristics.
