High chromium steel products

Our company has a lot of high chromium steel castings, most of the products containing chromium steel need to be tempered,This material is very hard

Chromium is one of the main alloy elements in heat - resistant steel.Chrome steel is made of chrome alloy steel, which is made of hard, hard, corrosion-resistant, corrosion-resistant and rust resistant.High oxidation resistance and corrosion resistance.Other elements such as molybdenum, vanadium, tungsten, titanium, niobium and boron are often added for different environments.Commonly used applications and steel grade 12 crmo (high, medium pressure steam pipe), 20 crmo (blade), 35 crmo (parts) used for a long time under 650 ℃, 1 cr5mo (reheater under 650 ℃, 650 ℃ erosion under strong sex of petrochemical equipment), 1 cr12mo (blade under 450 ℃).
