Technical Characteristics
Martensitic stainless steels are chromium-containing stainless steels whose mechanical properties can be significantly modified through heat treatment. Depending on grade and heat-treatment condition, they can provide a combination of high strength, hardness, wear resistance and moderate corrosion resistance.
Lower-carbon grades such as 410 are commonly used for general engineering components where strength and corrosion resistance are required, while higher-carbon grades in the 420 family can achieve greater hardness after appropriate heat treatment. Molybdenum- and vanadium-alloyed grades such as EN 1.4116 are commonly considered for cutting and wear-resistant applications.
Final material selection should consider required hardness, corrosion environment, heat-treatment condition, toughness, fabrication method and the applicable material specification.
Testing & Compliance Documentation
Testing and compliance requirements depend on the stainless steel grade, product form and intended application. Where required, available material certificates and applicable third-party test reports can be reviewed according to the purchase specification.
For cutlery, kitchenware or food-contact applications, buyers should specify the required migration test, food-contact requirement or applicable national/regional regulation with the inquiry. RoHS-related requirements should likewise be confirmed according to the specific product and intended use.
Typical Applications
Martensitic stainless steels are used where a combination of hardness, strength, wear resistance and corrosion resistance is required. Typical applications include industrial knives and cutting tools, kitchen cutlery, molds, valve components, turbine components, pump parts, measuring tools, springs and selected mechanical components.
410 is commonly considered for general engineering, valve and turbine-related components. Higher-carbon 420-family grades are widely used for cutting, wear-resistant and hardened components, while Cr-Mo-V grades such as EN 1.4116 are commonly selected for knife and cutlery applications.
The appropriate grade and heat-treatment condition should be selected according to required hardness, toughness, corrosion environment and manufacturing process.

Martensitic Stainless Steel FAQ
What is martensitic stainless steel?
Martensitic stainless steel is a family of chromium-containing stainless steels whose hardness, strength and wear resistance can be significantly modified through heat treatment. Common grades include 410 and the 420 family.
What is the difference between 410 and 420 stainless steel?
410 generally contains less carbon and is commonly used for engineering components requiring strength and moderate corrosion resistance. 420-family grades contain more carbon and can generally achieve higher hardness after suitable heat treatment.
What is the difference between 420J1 and 420J2?
420J2 generally has a higher carbon range than 420J1, allowing greater hardness potential after appropriate heat treatment. 420J2 is therefore commonly considered for knives, cutting tools, molds and wear-resistant components.
Is 1.4116 the same as 420J2?
No. EN 1.4116 (X50CrMoV15) and SUS420J2 are both martensitic stainless steels used in some overlapping applications, but they have different chemical compositions and standard designations. They should not be treated as automatic one-to-one equivalents.
Is 1.4116 suitable for knife manufacturing?
EN 1.4116 is a chromium-molybdenum-vanadium martensitic stainless steel widely associated with kitchen knives, cutlery and other cutting applications. Final performance depends strongly on heat treatment, blade geometry and manufacturing process.
Can martensitic stainless steel be supplied with a specified hardness?
Hardness depends on grade, heat-treatment condition, thickness and product form. Buyers requiring a target hardness should state the required hardness range, test method and delivery condition with the inquiry so that feasibility can be reviewed.
What information is required for a martensitic stainless steel quotation?
Please provide the grade, applicable standard, product form, thickness, width, length or coil size, quantity, surface condition, delivery condition, heat-treatment requirement, target hardness if applicable, inspection requirements and destination.
