SS 420 Plates

Overview of Stainless Steel as a Versatile Material

Stainless steel is recognized for its versatility, offering exceptional mechanical properties and performance characteristics. A crucial component of stainless steel is chromium, which contributes significantly to its excellent corrosion resistance and strength under high-temperature conditions. Additional alloying elements such as carbon, manganese, molybdenum, phosphorous, and niobium further enhance its mechanical strength, hardness, and wear resistance.

Multiple grades of stainless steel are available for various industrial uses, but one of the most extensively used grades for producing high-quality stainless steel plates is Grade 420.

About Stainless Steel 420 Plates

Stainless Steel 420 is a martensitic stainless steel grade that is widely preferred in industrial sectors due to its excellent characteristics and chemical composition. It includes significant amounts of vanadium, sulfur, and molybdenum, which enhance its hardness, strength, and corrosion resistance. Being a high-carbon martensitic grade, SS 420 offers good wear resistance and the ability to attain high hardness levels through heat treatment processes such as hardening and tempering.

Like other martensitic steels, SS 420's mechanical properties can be affected under extreme temperature conditions. It may lose strength at elevated temperatures and show reduced ductility at sub-zero levels.

Key Features and Properties of SS 420 Plates

SS 420 Plates exhibit a wide range of beneficial properties, making them suitable for use in demanding applications. Some of the major attributes include:

• Excellent corrosion and oxidation resistance
• High pitting resistance in corrosive environments
• Superior hardness and mechanical strength
• Good ductility and malleability
• Excellent weldability and machinability
• Good performance under thermal and mechanical stress

Due to these outstanding features, SS 420 plates are employed across a wide array of industrial applications including cutlery, surgical instruments, valves, and chemical processing equipment.
