Product Knowledge of 316L Stainless Steel Plates

Q1: Why do 430 stainless steel plates have magnetism?

A1: Because 430 belongs to ferritic stainless steel, its internal crystal structure is body-centered cubic structure, which is naturally magnetic. This is one of the core differences between it and 304, 316 austenitic stainless steel (non-magnetic), which can be quickly distinguished by magnetism.

Q2: What are the common application scenarios of 430 stainless steel plates?

A2: They are mainly used in home appliance inner tanks (refrigerator, washing machine inner tanks), kitchen utensils (cutlery, pot bases), architectural decoration (low-end walls, skirting lines), and industrial basic parts with low corrosion resistance requirements. The foreign trade demand is concentrated in the mid-to-low-end home appliance field.

Q3: What is the corrosion resistance of 430 stainless steel plates?

A3: The corrosion resistance is medium, better than 201 stainless steel, but weaker than 304 and 316 stainless steel. It can resist corrosion from the atmosphere and fresh water, but is easy to rust in salty, acid and alkali environments, and is not suitable for harsh scenarios such as coastal areas and chemical industry.

Q4: What is the price advantage of 430 stainless steel plates?

A4: The core advantage is low price. Because it does not contain nickel, the material cost is 40%-50% lower than 304 stainless steel and more than 60% lower than 316 stainless steel. It is suitable for foreign trade orders sensitive to cost and with low corrosion resistance requirements.

Q5: Can 430 stainless steel plates be used in food contact scenarios?

A5: Yes, it meets the food-grade stainless steel standard and can be used in food contact scenarios such as food processing tools and home appliance inner tanks. However, it is necessary to ensure that the surface is smooth and free of burrs to avoid residual food impurities, and food-grade test reports should be provided for foreign trade exports.
