What is 303 Stainless Steel?

303 stainless steel is in fact, free-machine variant of the common austenitic 18/8 stainless steel (namely, 304 stainless steel). This form has added sulfur or selenium to increase its machinability characteristic, which makes it better to cut, drill, and do all machining operations compared to the standard 304 grade stainless steel. Sulfur or selenium modification causes the formation of chips as internal tearing points, thus, improving the chip formation process and reducing the tool life. Machinability of 303 stainless steel is good. Though 303 stainless steel has less corrosion resistance and weldability compared to 304 stainless steel. The material is often used in machining where there are many machining procedures, such as turning, tapping, and milling of parts.

What Are the Characteristics of the 300 Series Stainless Steel?

The 300 series stainless steels which include 304and 316 grades are characterized by good corrosion resistance, non-magnetic properties in the annealed state and high ductility, strength, and formability, making them suitable materials for different applications. This property is due to the presence of chromium, and as such they have resistance to chlorides in the sea or in brackish water. Because of their attractive formability and high-temperature resistance, they are perfect for manufacturing complex products and demanding applications where the parts are subjected to high temperatures, like heat exchangers and exhaust systems. These so-called stainless steels are widely used throughout the automotive, aerospace, food processing, chemical, architectural, and medical industries because of the combination of properties that they offer, enabling them to operate in situations requiring that combination.

What Are the Differences Between the 200, 300, and 400 Series Stainless Steel?

The 200,300, 400 series of stainless steel have compositional differences, corrosion resistance, magnetic properties and applications. The 200 series is made of chromium, nickel, and manganese which present some minor corrosion resistance, being at the same time non-magnetic. On the other hand, 300 series which is known due to its composition from chromium and nickel, stands out as a material with excellent corrosion resistance property, non-magnetic property, as well as versatility for various industries. In the 400 series, with chromium as the primary alloying metal, it shows a lesser degree of corrosion resistance and is magnetic, hence, commonly used in cutlery and decorative trims. In general, the 200 series is used for the cookware and the 300 series is highly applicable for the corrosion resistance and wide availability, therefore, the 400 series is intended for the magnetic applications that require a moderate corrosion resistance.
