SS 420 (UNS S42000)Round Bars/Rods,Grade 420 steel is indeed known for its ductility, corrosion resistance, and other valuable properties. Here are some key features and applications of Grade 420 steel:
-
Ductility and corrosion resistance: Grade 420 steel offers good ductility and corrosion resistance, particularly when polished. Polishing the surface of the steel makes it smoother and harder, enhancing its resistance to corrosion.
-
Excellent forming and welding properties: Grade 420 steel exhibits excellent forming and welding properties, allowing it to be shaped and joined without cracking. This makes it suitable for various fabrication processes and applications.
-
Application in kitchenware and hollow-ware: Due to its corrosion resistance, excellent forming properties, and high tensile strength, Grade 420 steel is commonly used in the manufacturing of sinks, hollow-ware (e.g., cookware), and saucepans. These applications benefit from the steel's durability and resistance to corrosion.
-
Low maintenance requirements: Grade 420 steel requires little maintenance, making it a preferred choice in applications where regular upkeep is not desirable. This can contribute to cost savings and ease of use.
-
High durability and flexibility: The high tensile strength and durability of Grade 420 steel make it suitable for applications where strength and flexibility are important. It can withstand mechanical stress and pressure without compromising its performance.
-
Pitting resistance: Grade 420 steel exhibits resistance to pitting, which is the localized corrosion that can occur in certain environments. This property makes it suitable for applications where exposure to corrosive substances is expected.
