Alloy Steel Investment Casting

Description

Investment casting is a common casting scheme. The types of alloys that can be produced by investment casting are carbon steel, alloy steel, heat-resistant alloy, stainless steel, precision alloy, permanent magnet alloy, bearing alloy, copper alloy, aluminum alloy, titanium alloy and ductile iron. The investment casting process is complex and difficult to control, and the materials used and consumed are expensive, so it is suitable for the production of small parts with complex shape, high precision requirements, or difficult to carry out other processing.

Features

This Alloy Steel Investment Casting is a kind of medium hardened steel with good processability, small deformation and good fatigue resistance. After heat treatment, the product has good strength and comprehensive mechanical properties. Its maximum operating temperature is 427 ° C. The product has high strength, high quenching capacity, good toughness, small deformation, high creep strength and high temperature endurance strength. It is used to manufacture forgings with higher strength than 35CrMo steel and higher cross section quality, such as big gear, booster drive gear, rear axle, load bearing link and spring clip, as well as joints, fishing tools and bending machine dies for deep wells below 2000m.
