The strength of stainless steel plates and ordinary steel plates is different, which is determined by their material and production process.

Stainless steel plate is a material with high corrosion resistance, high strength, and high temperature stability, composed of iron, chromium, nickel, and other elements. Stainless steel plates are generally more resistant to corrosion, high temperatures, and abrasion than ordinary steel plates. The strength of stainless steel plate is relatively high, which can reach the strength level of ordinary steel plate, or even higher.

Ordinary steel plates are composed of elements such as iron and carbon, and their strength mainly depends on the carbon content and manufacturing process. Compared to stainless steel plate, ordinary steel plate has a certain degree of toughness and ductility, and is suitable for various mechanical processing, cold processing, and hot processing processes.

In some special application fields, such as aviation, nuclear power, shipbuilding, and other highly demanding fields, higher strength materials are required. At this time, stainless steel plates can usually reach or even exceed the strength level of ordinary steel plates, so the application range of stainless steel plates is also expanding.

In general, stainless steel plate and ordinary steel plate have different characteristics and application fields, and different materials can be selected according to different application scenarios and requirements.
