Cold Rolled DC04EK Porcelain Enamel Steel Sheet For Water Heater Liner

Our Cold-Rolled DC04 Enameling Steel is a premium, extra-deep drawing quality substrate specifically engineered for porcelain enameling applications within the global home appliance industry. "DC04" represents the pinnacle of cold-reduced low-carbon steel ductility, while the "Enameling Grade" features a specialized chemical formulation (often vacuum-degassed or titanium-stabilized) designed to optimize hydrogen storage capacity within the metal matrix.

This critical metallurgical control completely prevents the industry's biggest headache—fishscaling—and guarantees a flawless, high-strength bond between the steel and the enamel coating. It is the definitive material choice for manufacturing complex, deep-drawn components that require liquid or powder enameling, such as premium oven baking trays, gas hob top plates, barbecue grill grates, and water heater inner tanks.

Feature

1. Superior Extra-Deep Drawing Performance: With an exceptionally high elongation rate and optimal plastic strain ratio, DC04 steel flows effortlessly into deep, intricate molds during high-speed stamping without tearing or micro-cracking.

2. Excellent Anti-Fishscaling Resistance: The micro-alloyed structure creates uniform hydrogen traps, ensuring that hydrogen gas escapes safely without blistering or chipping the fired porcelain glaze.

3. Flawless Enamel Adherence & Surface Finish : The surface texture is meticulously controlled via textured cold-rolling to provide the perfect microscopic roughness, maximizing the chemical and mechanical bond of the enamel layer.

4. High-Temperature Structural Stability : Engineered to maintain strict dimensional flatness and structural integrity during the extreme thermal cycles (800-860 °C)of the enamel firing process.
