ASTM A276  UNS S31803 Round Bars are made from high-quality raw materials and advanced technology. These round bars are commonly used for various purposes in various sectors. ASME SA276 UNS S31803 Round Bars are widely used for high-temperature applications. 

ASME SA276 UNS S31803 Round Bars can effortlessly withstand high temperature and bad weather conditions. These round bars are available in various types and ranges, and the grade has immense strength and ductility, which makes this grade more. These round bars are commonly known as an austenitic mixture of steel. ASTM A276 / ASME SA276 UNS S31803 Round Bars can not be hardened by high heat treatments, and these bars only get stronger by cold workings.

Chemical combinations: 

The chemical combination of these round bars includes a high amount of chromium, nickel, and molybdenum. The garden also consists of carbon, manganese, phosphorous, sulfur, iron, and nitrogen. These elements are known for adding up excellent characteristics to the grade. 

Duplex Steel S31803 Round Bars get utmost stability from this chemical composition. It improvises its texture and provides immense texture and smoothness to the alloy. ASTM A276 / ASME SA276 UNS S31803 Round Bars provide excellent protection from various heat and chemical reactions. The grade delivers extraordinary resistance from corrosion, crevice corrosion, and stress cracking. It also allows procedures like forging between 1100°C-1250°C; similarly, the grade also allows annealing at 1020°C-1120°C.

Characteristics

  • High resistance to chloride stress corrosion cracking
  • Resistance to chloride pitting and crevice corrosion
  • Good general corrosion resistance
  • Good sulfide stress corrosion resistance
  • High Strength
  • Good weldability and workability

Applications

  • Chemical process vessels, piping and heat exchangers
  • Pulp mill digesters, bleach washers, chip pre-steaming vessels
  • Food processing equipment
  • Oil field piping and heat exchangers
  • Flue gas desulfurization equipment
