Find Out if Alloy 310 Stainless Steel is Right for Your Business

Companies who use quality metal in their processes set an industry standard that competitors who cut corners can never reach. Whatever your industry, you should only use reliable alloys for your piping needs. If you need stainless steel pipes, valves, or fittings that resists corrosion for your high-temperature applications, contact James Duva Inc for alloy 310. As a pipe distributor, we have all your alloy needs in one place.

Check Out the Design Features and Applications of 310

Many different companies use alloy 310 for a variety of high-pressure piping purposes. This heat-resistant alloy stays strong at elevated temperatures. It can withstand continuous exposure to temperatures of 2100 degrees Fahrenheit without negative effects. 310 also has a lower coefficient of expansion than other products in the 300 stainless steel line, which makes it perfect for its use in petroleum refining.

Other industry applications for 310 include:

  • Thermal processing
  • Power generators
  • Ore processing
  • Furnace components
  • Food processing
  • Cryogenic components

Alloy 310 has high levels of chromium and moderate levels of nickel, which allow this alloy to resist corrosion from exposure to sulfuric environments. This material also resists corrosion better than types 309 and 304. At James Duva Inc, we make our 310S with high carbon in order to meet 310H specifications.
