When it comes to selecting the right material for your industrial needs, understanding the various grades of martensitic stainless steel is crucial. As a leading manufacturer, Normandy Metal is committed to providing high-quality martensitic stainless steel that meets the specific requirements of bulk purchasers. In this article, we’ll delve into the different grades of martensitic stainless steel, focusing on their unique properties, applications, and considerations for bulk procurement.
Common Stainless Steel Martensitic Grades
Grade 410 is one of the most widely used martensitic stainless steel. Known for its excellent hardness and moderate corrosion resistance, it is commonly used in applications such as cutlery, fasteners, and valves. The material’s high carbon content allows it to be heat-treated to achieve a wide range of mechanical properties, making it versatile for various industrial applications.
Cutlery and Kitchenware: Grade 410 is often used in the production of knives and other kitchen tools due to its ability to maintain a sharp edge.
Industrial Fasteners: Its strength and durability make it ideal for fasteners that need to withstand high stress and wear.
Valves and Pumps: The material’s moderate corrosion resistance ensures longevity in mildly corrosive environments.
For bulk purchasers, stainless steel martensitic grades 410 offers a cost-effective solution without compromising on quality. Normandy Metal provides competitive pricing and consistent quality, ensuring that your large-scale projects are both economical and reliable.

Grade 420 martensitic stainless steel is known for its higher carbon content compared to Grade 410, which results in increased hardness and wear resistance. This grade is often used in applications requiring high strength and excellent edge retention, such as surgical instruments, cutting tools, and bearings.
Surgical Instruments: Grade 420 is ideal for medical tools that require precision and durability.
Cutting Tools: Its high hardness makes it perfect for blades and other cutting instruments that need to maintain sharpness over time.
Bearings: The material’s wear resistance ensures long-lasting performance in high-stress environments.
Bulk purchasers will appreciate the enhanced properties of Grade 420, especially for applications requiring superior hardness and wear resistance. Normandy Metal’s advanced manufacturing processes ensure that you receive consistent quality across large orders, meeting the stringent demands of your industry.
Specialty Stainless Steel Martensitic Grades
Grade 440C is a high-carbon martensitic stainless steel known for its exceptional hardness and wear resistance. It is often used in high-precision applications such as ball bearings, valve components, and high-end cutlery. The material can be heat-treated to achieve a hardness of up to 60 HRC, making it one of the hardest martensitic stainless steels available.
Ball Bearings: Grade 440C’s high hardness and wear resistance make it ideal for precision ball bearings.
Valve Components: Its ability to withstand high stress and wear ensures long-lasting performance in critical applications.
High-End Cutlery: The material’s superior edge retention makes it a popular choice for premium knives and cutting tools.
For bulk purchasers, Grade 440C offers unparalleled performance in demanding applications. Normandy Metal’s commitment to quality and precision ensures that you receive top-tier material that meets your exact specifications, even in large quantities.
Grade 431 martensitic stainless steel is known for its excellent toughness and corrosion resistance, making it suitable for marine applications, pump shafts, and aircraft components. The material’s balanced properties make it a versatile choice for industries requiring both strength and corrosion resistance.
Marine Applications: Grade 431’s corrosion resistance makes it ideal for use in marine environments.
Pump Shafts: Its toughness ensures reliable performance in high-stress applications.
Aircraft Components: The material’s balanced properties make it suitable for various aerospace applications.
Bulk purchasers will find Grade 431 to be a reliable and versatile option for a range of applications. Normandy Metal’s scalable production capabilities ensure that you receive consistent quality and timely delivery, regardless of order size.
