10H11N20T2R (EI696)
Technical characteristics
Stainless alloy 10Х11Н20Т2Р (ЭИ696) heat-resistant high-alloy. is a chromium-manganese-nickel alloy of austenitic class with intermetallide hardening. It is melted in open arc furnaces. Maximum operating temperature allows prolonged operation up to +700 ° C. Intensive scale formation in the air begins above +850 ° C. Stainless alloy EI696 can withstand long-term exposure to chemically active environments, such as acid or alkaline environment of industrial gases.

The supplier guarantees the high quality of the product. Cerium, zirconium and boron are added to the alloy by calculation and are not usually determined by chemical analysis. The alloying effect on the quality of the steel is multifaceted. Chromium increases hardness and corrosion resistance. Nickel makes the alloy ductile; tungsten makes it hard and red-hot. Vanadium increases strength, resistance to impact and abrasion; Molybdenum makes the alloy red-hot and hard, prevents oxidation at high temperature. Manganese content above 1% increases impact strength, wear resistance. Titanium increases stability, corrosion resistance; aluminum - resistance to scale formation; Copper increases ductility, prevents rusting.
