OEM Alloy Steel Investment Casting – Chrome Molybdenum Steel Investment Casting Product Detail:

China OEM custom Chrome Molybdenumalloy steel investment casting products with CNC machining services.

Carbon steel, low alloy steel, high alloy steel and tool steel castings are used in several industrial applications. With their numerous grades, steel and their alloys can be heat-treated to improve its yield and tensile strength and, adjust hardness or ductility to the engineer’s application needs or desired mechanical properties.

Using the investment casting process, RMC casting foundry is capable of meeting material specifications according to ASTM, SAE, AISI, ACI, DIN, EN, ISO, and GB standards. We have more than 100 different ferrous and non-ferrous alloys with which we cast parts using complex design criteria. Our dimensionally and geometrically complex investment castings are produced to net shape, minimizing the need for secondary machining.

Chromium-molybdenum cast steel is widely used in industrial fields with relatively high mechanical properties. The addition of molybdenum to chromium steel can increase the strength of steel castings without having a significant impact on the impact toughness of cast steel. Moreover, chromium-molybdenum cast steel has very good high temperature performance and creep resistance. After quenching and tempering or normalizing heat treatment, chromium-molybdenum cast steel can obtain excellent mechanical properties.

Molybdenum can improve the hardenability of cast steel and reduce the temper brittleness of cast steel. Chromium-molybdenum cast steel is used for large-section castings and steel castings that require deep hardening.
