Stainless Steel Pipe Fittings

1,740 products

Stainless steel pipe fittings are extremely corrosion resistant. Stainless steel offers good thermal and electrical conductivity, but these properties are comparatively weak relative to other metal materials. 304 stainless steel is a chromium-nickel material with very good corrosion resistance. Type 316 stainless steel has a higher nickel content than 304 stainless, plus molybdenum, for even greater corrosion resistance. Pipe fittings are used to connect straight sections of pipe, adapt to different sizes or shapes, and for other purposes such as regulating or measuring fluid flow.
