Today a large range of materials are used in broad spectrum of aggressive chemicals. As chemicals and their properties vary on a large level, it is tough to select a suitable material for a specific chemical application. Commonly used materials in chemical applications are: 316 stainless steel- An alloy of iron, carbon, nickel and chromium, … Continue reading Best alloys for use in chemical media

Duplex Stainless Steel- Austenitic Ferritic stainless steels were initially made for use in the paper plants to prevent corrosion problems due to chloride bearing cooling water and other aggressive chemical process fluids. Containing high concentration of chromium, nitrogen, and molybdenum, these steel materials provide supreme resistance to localized and uniform corrosion. Their duplex structure introduces … Continue reading Which alloys can be used in gas extraction and purification plants?

AISI 300 series Stainless Steel Many changes have been made with austenitic stainless steels. Stainless steel 300 series alloys with C: 0.08%, Cr: 16%, Ni: 8%, P: 0.045%, S : 0.04%, Mn: 2% and Si: 2% and with other permitted composition elements are solution heat treated and free for cold work to enhance their mechanical … Continue reading Which alloy is best to resist Sulfide stress cracking and Stress corrosion cracking?

Hastelloy alloys are known for offering supreme corrosion resistance and elevated temperature strength. Hastelloy B is used in several high temperature applications including forged supercharger blades, engine rings and rocket nozzles. Hastelloy B3 is made for service in corrosion resistant, high temperature and high strength applications. An inclusion of chromium is beneficial for high temperature … Continue reading Which alloy offers the highest oxidation resistance?

Superalloys are also called as Heat Resisting Alloys or High Temperature alloys that are extremely important materials. Superalloys are rich in nickel, cobalt and iron. These maintain structural surface and retain their characteristics at the high temperatures under extreme stress and in vigorous environment.   Over the time titanium, aluminum and chromium are successfully added … Continue reading Which Superalloys are highly in demand among worldwide industries?
