Melting Point: 1340 ¡æ -1390 ¡æ

Magnetic properties: None

GH3128 welding performance

1. Plate welding good performance, can be used welding, seam welding and spot welding methods such as welding, can be satisfied with the quality of welded joints, joint strength factor greater than 90%;

2. Can GH3044, GH3039, GH1140, GH3030, and welding sheet 1Cr18Ni9Ti so.

GH3128 parts heat treatment

1. Afterburner aircraft engine parts solution treatment temperature of 1200 ¡æ ¡À 10 ¡æ, air cooling;

2. Combustor liner components of the solution temperature was 1160 ¡æ ¡À 10 ¡æ;

3. When Stamping parts many times in the middle of the treatment temperature was 1100 ¡æ ¡À 20 ¡æ, holding time and the thickness of the part determined in furnace installed.

GH3128 surface treatment

Working under high temperature components in W-2 can be used to effectively protect the enamel coating
