Furnace Heat Treatment Protective Gas
Flr heat treatment shielding gas is a gas mixture used to prevent scaling and decarburization during heating. It protects surface integrity without mechanical post-treatment.
Physical-chemical mechanism of action
Flr heat treatment shielding gas consists of a special gas mixture used during heating. It prevents scaling and decarburization of the surface through a continuous protective layer. This protects the metal structure from chemical attack and eliminates mechanical post-treatment.
Metallurgical relevance & risks during welding
Without proper shielding gas, heating steel can cause scaling and decarburization, affecting surface integrity. This can lead to cracks or poor surface quality. Flr heat treatment shielding gas prevents these issues by providing a continuous protective layer.
Workshop practice & instructions
Use Flr heat treatment shielding gas when heating steel. Ensure the gas is introduced into the process and forms a tight protective layer. The exact gas concentration depends on the steel analysis and should follow the manufacturer's specifications. Improper use can damage the surface, leading to cracks or poor surface quality.
