High-Temp & Deep-Drawing Steel for Microwave Ovens and Range Cavities

High-Temperature & Deep-Drawing Steel for Microwave Ovens and Integrated Ranges

Cooking appliances like microwave ovens, electric ovens, and built-in cooking ranges subject internal steel components to extreme conditions: repeated thermal expansion, high mechanical stress during deep drawing, and exposure to corrosive food acids.

Selecting high-formability, heat-resistant steel grades ensures clean drawn corners without cracking while keeping material costs competitive.

Critical Steel Material Requirements for Cooking Appliances

1. Microwave & Oven Inner Cavities (Deep-Drawing Performance)

• Best Material: Cold-Rolled Steel for Deep Drawing (SPCD, SPCE, DC03, DC04).

• Why It Works: These grades offer high elongation rates and uniform yield strength, essential for hydraulic drawing into box-like cavities without tearing at the corners.

2. Baking Trays, Drip Pans & Heat Shields

• Best Material: Enameling Quality Steel (RTC) or AISI 430 / 304 Stainless Steel.

• Why It Works: Grade 430 offers low thermal expansion and high heat resistance up to 800°C, making it ideal for oven interiors, baking sheets, and burner flame shields.

3. Outer Housing & Control Panels

• Best Material: Cold-Rolled SPCC with Anti-Fingerprint Stainless Steel or Brushed Finish.

• Why It Works: Combines modern aesthetics with grease and fingerprint resistance for premium kitchenware aesthetics.

Advantages of In-House Slitting & Stamping Pre-Delivery

Purchasing pre-slitted coil strips or pre-cut sheet blanks directly from Guangdong Juhua Steel gives cooking appliance OEMs key production advantages:

• Zero Edge Burr: Protects sensitive deep-drawing rubber pads and carbide dies from excessive wear.

• Exact Blank Sizing: Eliminates shearing scrap inside the client's assembly line.

• Custom Stamping: Pre-punched ventilation holes and mounting slots ready for immediate assembly.
