Alloy 20 / 20Cb3 Round Bars

Alloy 20 / 20Cb3 Round Bars

Because of its excellent and incomparable qualities, alloy 20 is a grade that is well-known across the industrial sector. The alloy, often called Carpenter 20, is made of a chromium-nickel-iron alloy and was created to offer great resistance to various acidic conditions. The Superalloy also provides:

  • Strong crevice corrosion resistance.
  • Chloride environment pitting resistance.
  • Stress crack corrosion resistance to the manufactured round bars.

As a result, the grade is suitable for use in producing round bars. When it comes to the graded alloy 20Cb3, it is an austenitic SS with excellent resistance to acidic situations, including sulfuric acid. It delivers the round bars maximal strength even in high temperature and pressure environments and demonstrates high resistance to stress crack corrosion. The grade’s superior chemical composition gives round bars exceptional qualities like high tensile and yield strength and high short creep capabilities. The alloy’s carbon, silicon, manganese, phosphorous, and chromium composition makes it extremely robust and durable under adverse conditions. As a consumer, you have a variety of industries to choose from that offer high-quality Alloy 20/20Cb3 Round Bars. Some industries are these bars’ top producers, exporters, and trustworthy suppliers. The round bars are also subjected to pertinent material tests to ensure their high standards of quality and effectiveness. Some tests include mechanical testing, hardness tests, pitting resistance tests, and positive material identification tests.
