Product Description

1. Introduction of GH16:

GH16 is a FE-NI-CR based alloy, which is solid solution strengthened with elements such as chromium, tungsten and molybdenum.

The alloy can be used for a long time below 950 degrees and for a short time below 1000 degrees.

The alloy has good oxidation resistance, high plasticity, high thermal strength and good cold and thermal fatigue resistance, and the alloy has good cold stamping performance.

2. GH16 application and features:

When GH16 works for a long time at 700~900 degrees, aging hardening phenomenon occurs, which leads to a decrease in room temperature plasticity and a slight decrease in high temperature lasting strength.

When the alloy works for a long time above 700 degrees, grain boundary oxidation occurs, and it is resistant to high temperature above 1000 degrees.

The oxidizing property is slightly worse than that of nickel-based alloys for similar purposes, and the alloys can be used as substitutes for GH3030, GH3039, and 3044.

It is used for engine stamping parts and welding parts and other high temperature parts and parts that work for a short time below 1000 degrees.

GH16 processing and welding performance:

The GH16 as-supplied plate has good plasticity and is often carried out at room temperature.

Solution treatment is required after stamping the parts.

Before deep drawing, the surface needs to be coated with nitro varnish.

The alloy has good welding performance, and the alloy is commonly used in argon arc welding.

The oxidation resistance of the alloy is worse than that of the nickel-based alloy, and attention should be paid to strengthening protection.

When seam welding thick plates, pay attention to the rest time per hour to prevent cracks.
