What Makes 430 Stainless Steel Magnetic?

For steel to be magnetic, it must contain iron and have either a martensitic or ferritic crystal structure. Magnetic alloys must contain iron. A martensitic or ferritic crystal structure must be present in the alloy

There is a magnetic property to ferritic stainless steel grade 430. Austenitic stainless steel grade 304 does not exhibit magnetic properties, but it may become magnetic after being cold worked (bending, deforming). Grade 316 austenitic stainless steel is not magnetic

• Bendability – Good
• Tensile Strength -Excellent
• Cold Working – Good
• Corrosion Resistance – Excellent 
• Heat Resistance – Good
• Heat Treatment – Poor
• Hot Working – Fair
• Machinability – Good
• Weldability – Very Good

How Does 430 Differ To 304 Stainless Steel?

Stainless steel is a highly versatile and widely used metal, particularly for its high resistance to corrosion. In stainless steel, there are several grades, each with unique properties that make it suitable for specific applications. The two most common grades are 430 and 304.

430 and 304 stainless steel are part of two different families within the stainless steel classification: the 400 series and the 300 series respectively. A ferritic stainless steel belongs to the 400 series, which includes 430 grade. There is a wide range of chromium content in this series, ranging from 10.5% to 27%, but nickel is not present. In this way, 430 grade stainless steel has magnetic properties, a characteristic not commonly found in other grades. In addition to its good formability, the 430 grade is known for its high resistance to stress corrosion cracking. Despite its corrosion resistance, it is less resistant than 304 grade.

While 304 grade belongs to the austenitic stainless steel family, the 300 series is known as austenitic stainless steel. The primary difference between 304 and 430 stainless steel is the presence of nickel in the 304 grade, which can range from 8% to 10.5%. The combination of nickel and a higher content of chromium (between 18% to 20%) gives 304 stainless steel excellent corrosion resistance, surpassing that of 430 stainless steel. In applications where the material will be exposed to corrosive environments, this characteristic makes it highly desirable. It is also non-magnetic and exhibits excellent formability and weldability, making it highly versatile for a wide range of applications.

Due to the absence of nickel, 430 grade stainless steel is generally less expensive than 304 grade stainless steel. The low cost and superior corrosion resistance of 304 make it a popular choice in applications where cost is a major factor.

As a result, even though both 430 and 304 stainless steels are commonly used materials, their properties and uses can differ significantly. The choice between the two will largely depend on the specific requirements of the application, such as corrosion resistance, formability, weldability, cost, and magnetic properties.
