Audited Supplier High Quality Stainless Steel S53008 Austenitic Stainless Valve Steel SUH35 Antioxidant 21-4N Wear-Resistant 53Cr21MnNi4N with Engine Exhaust Valve
Application:
Valve steel is an essential material used to manufacture intake and exhaust valves for gasoline and diesel engines, and is a critical material for the entire engine. 21-4N is the main material used for exhaust valves in engines. Compared with intake valves, exhaust valves work under higher temperature, greater pressure, and stronger corrosion, which requires higher material requirements and is the most crucial part of the engine.
Ingredient Design:
The system has considered the influence of alloying elements such as C, Cr, Ni, and N on the material's strength, toughness, oxidation resistance, wear resistance, and microstructure stability, and has conducted a deep optimization of material composition, significantly improving the product's overall performance.
Production Process:
Electric furnace+out-of-furnace refining+high temperature homogenization+special forming process
Product Features:
High purity, low segregation, no layered precipitate, uniform structure, strong toughness, antioxidant, wear-resistant, and tissue stability.
