Stainless steel coils are one of the core raw materials in the home appliance industry due to their strong corrosion resistance, smooth and easy to clean surface, stable mechanical properties, and durability. They are widely used in the structural, appearance, and functional components of various home appliances such as refrigerators, washing machines, water heaters, and kitchenware. According to the type of household appliances, the specific application scenarios are as follows:
1、 Refrigerator/Freezer: Core Structure and Exterior Components
1. Inner liner and back panel
304 cold-rolled stainless steel coil (2B side) is selected, with a smooth surface and no dead corners. It is resistant to low temperature and humidity, not easy to breed bacteria, and can withstand the temperature changes of the refrigeration system (-40 ℃~60 ℃). It will not rust or deform after long-term use.
The drawer rails and shelf brackets of some refrigerators are also made of stainless steel coil stamping, which has high strength and good load-bearing capacity.
2. Door panel and door frame
The door panel of the refrigerator is made of brushed or mirrored stainless steel coil (BA surface), with good texture, anti fingerprint, easy to wipe, and enhances the product's appearance; The door frame is made of stainless steel coil bending processing, which has good sealing and is not easily deformed.
3. Condenser/evaporator components
The pipeline brackets and heat sinks of the refrigerator refrigeration system are made of 430 ferritic stainless steel coils, which have low cost, good thermal conductivity, and meet the requirements of rust prevention and heat dissipation.
2、 Washing machine: water-resistant and wear-resistant functional components
1. Inner cylinder and outer cylinder
The inner drum of a drum washing machine is the core application scenario of stainless steel coils. It uses 304 cold-rolled stainless steel coils, which are stamped, welded, and polished to have a smooth and burr free surface, resistant to laundry detergent corrosion, strong wear resistance during high-speed rotation, and will not damage clothes.
Some models also use stainless steel coils for the outer tube, replacing traditional plastic outer tubes, which have a longer service life and better sound insulation effect.
2. Door frame and hinge
The door frame and cover bracket of the washing machine are made of 304 or 201 stainless steel coils, which are resistant to corrosion in humid environments. They have excellent load-bearing and stability when opening and closing doors, avoiding rust and deformation after long-term use.
3、 Water heater: a safe and durable pressure bearing component
1. Inner liner
The inner tank of a storage type electric water heater is a key pressure bearing component, made of 304 or SUS444 stainless steel coils, welded and enamel treated, resistant to high pressure (usually 0.6~1.0MPa pressure) and hot water corrosion, eliminating the risk of water leakage.
The heating chamber of the instant water heater is made of thin-walled stainless steel coil stamping, which has fast thermal conductivity and resistance to high temperature scale adhesion.
2. Shell and bracket
The shell panel of the water heater is made of brushed stainless steel coil, which is beautiful, rust proof, and suitable for humid environments in kitchens and bathrooms; The installation bracket is made of 430 stainless steel coil, which has strong load-bearing capacity and can be hung for a long time without deformation.
4、 Kitchen appliances: hygiene grade core components
1. Gas stove/range hood
The panel and frame of the gas stove are made of 304 stainless steel coils, which are high temperature resistant (able to withstand high-temperature flame baking), resistant to oil and corrosion, and easy to clean; The filter screen and smoke collection chamber of the range hood are formed by stamping stainless steel coils, which are resistant to oil fume adhesion and easy to disassemble and clean.
2. Microwave/oven
The inner liner of the microwave oven is made of 304 stainless steel coil, which is resistant to high temperature and microwave radiation, and does not absorb oil stains. It will not release harmful substances when heating food; The inner pot and baking tray of the oven are made of heat-resistant stainless steel rolls, which can withstand high temperatures above 250 ℃ without deformation.
3. Dishwasher/Disinfection Cabinet
The inner pot and spray arm of the dishwasher are made of 304 stainless steel coils, which are resistant to hot water and detergent corrosion, and have strong wear resistance during high-speed spraying; The shelves and inner tanks of the disinfection cabinet utilize the hygienic properties of stainless steel to prevent bacterial growth and comply with food grade safety standards.
5、 Small appliances: delicate and durable functional components
1. Electric rice cooker/electric pressure cooker
The stainless steel composite layer of the inner liner is made of ultra-thin 304 stainless steel coils, which are combined with materials such as aluminum and copper to achieve both thermal conductivity uniformity and corrosion resistance; The sealing ring bracket of the pot lid is made of stainless steel coil stamping, with stable sealing performance.
2. Blender/Wall Breaker
The blade assembly and inner liner of the mixing cup are made of 304 stainless steel coils, which are resistant to high-speed rotation and wear, and meet food contact safety standards. They will not release heavy metals when polishing ingredients.
