4Cr5MoSiV1 Automotive Engine Mould Steel, 4cr5mosiv1 is a metal alloy whose composition includes chromium (Cr), molybdenum (Mo), silicon (Si) and vanadium (V). It is a high-strength, corrosion-resistant alloy commonly used in the aerospace, automotive manufacturing, and chemical industries. 4cr5mosiv1 has good high-temperature strength and corrosion resistance, and 4Cr5MoSiV1 steel has a higher vanadium content compared to 4Cr5MoSiV steel, which results in a better performance in medium-temperature (600 degrees Celsius). The executive standard of this material is GB/T1299-2000, and the unified numerical code is A20502. Therefore, it is commonly used in the manufacture of aero-engine components, turbine blades, and high-temperature structural parts. In the field of automobile manufacturing, the application of 4cr5mosiv1 is also very wide, can be used in automobile engine and exhaust system, can withstand high temperature and corrosive environment. 4Cr5MoSiV1 is also a kind of alloy tool…
