Stainless steel can be broadly classified into several types, including austenitic, ferritic, martensitic, and duplex stainless steels. Each type has its own unique composition and properties.
304 stainless steel is an austenitic stainless steel, non-magnetic, while 410 stainless steel is a martensitic stainless steel, magnetic. The main difference between the two is in their chemical composition. 410 stainless steel contains a higher percentage of carbon, which makes it harder and more durable than 304 stainless steel.
It is noteworthy that magnetic attraction is not a reliable method for testing the quality or composition of stainless steel.
While non-magnetic stainless steels like 304 are commonly used in various applications, its important to note that magnetic stainless steels, such as 410, also have their own advantages. They offer good mechanical properties, high hardness, and improved wear resistance, making it ideal for use in applications such as machinery parts, bolts, and nuts, especially in high-stress environments. Its also resistant to corrosion and can withstand high temperatures, which makes it suitable for use in industrial and manufacturing settings.
