It belongs to austenitic stainless steel (300 series), which is an improved type of 304 stainless steel with increased nickel (Ni) and chromium (Cr) content, and is specially designed for high temperature oxidation and corrosion resistance.

Application scenarios
1. High-temperature industrial environment
Heat treatment equipment: annealing furnace, carburizing furnace, quenching furnace furnace tubes, brackets, conveyor belts.
Boiler and energy: superheater pipes, combustion chamber components of coal-fired boilers, chimney linings.
Petrochemical industry: refinery heating furnace, cracking furnace pipe fittings, high-temperature reactor internals.
2. Metallurgy and glass industry
Metallurgical kilns: annealing furnace cover and heat treatment fixtures in steel plants.
Glass production: heat-resistant components of glass melting furnaces (such as feed ports, stirrers), high-temperature conveyor belts.
3. Incineration and environmental protection equipment
Waste incinerator: combustion chamber, flue gas duct, high-temperature resistant lining.
Waste gas treatment: high-temperature components in industrial waste gas purification equipment (such as catalytic combustion devices).
4. Kitchen and commercial equipment
Commercial ovens/baking ovens: high-temperature furnaces, grills, exhaust pipes.
Food processing machinery: conveyor belts or containers that require long-term high-temperature operation (such as baking equipment).
5. Aerospace and special parts
Aircraft engine auxiliary parts: high temperature resistant brackets and exhaust pipes in non-core parts.
Special vehicles: exhaust system components of racing cars or high-performance vehicles (such as exhaust pipes, turbocharger housings).
6. High temperature corrosion resistant chemical scenes
Dilute acid environment: such as storage tanks or pipelines of dilute sulfuric acid and phosphoric acid (when the concentration is low).
High temperature water medium: high temperature and high pressure water pipelines of thermal power plants (note: not suitable for high chloride or strong corrosion environments).
