Product Description
DIN 28Cr4/1.7030 QT Alloy Structrural Steel
1: 28Cr4 Steel Introduction
28Cr4 is mainly composed of iron, chromium and small amounts of carbon, silicon, manganese and other elements. Chromium is the main alloying element, with a content of 28%, hence the name 28Cr4. Carbon content is lower, at 0.4%. In addition, the addition of silicon, manganese and other elements for the strengthening of steel and corrosion resistance also play a role. 28Cr4 has good mechanical properties, including high strength, high hardness, good wear resistance and corrosion resistance.
