Its higher carbon content compared to 410 allows for superior hardening and wear resistance, while maintaining good corrosion resistance in mild environments. As a leading AISI 420 Supplier and ASTM A276 420 Stockiest, we highlight its core benefits:
Very High Hardness & Strength (Maximized by Heat Treatment)
Can be hardened by quenching and tempering to achieve exceptional hardness (up to 50 HRC and beyond) and very high tensile strength, making it ideal for cutting tools and wear-resistant components, from an expert AISI 420 Manufacturer.
Good Corrosion Resistance in Mild Environments
Offers good resistance to atmospheric corrosion, fresh water, steam, weak acids, alkalis, and some food acids. Its corrosion resistance is maximized in the fully hardened and highly polished condition, fulfilling requirements of an EN 1.4021 Exporter.
Excellent Wear Resistance
The high hardness of AISI 420 contributes to its outstanding wear resistance, making it suitable for applications subjected to abrasion and friction, meeting BS 970 420S29 standards.
Magnetic Properties
Being a martensitic stainless steel, AISI 420 is magnetic in both the annealed and hardened states, which can be advantageous for certain electromechanical applications, compliant with AFNOR Z20C13.
Fair Machinability
Exhibits fair machinability, best performed in the annealed or sub-critical annealed condition to minimize tool wear, from a reliable GOST 20Х13 Supplier.
Widely Accepted Globally
A globally recognized and preferred grade for many critical applications requiring maximum hardness, strength, and wear resistance with moderate corrosion properties, ensuring wide compatibility, thanks to our global network as an AS 420 Exporter.

Stainless Steel ASTM A276 / AISI 420 Bars — Frequently Asked Questions
Find answers to common questions about AISI 420 Manufacturer production, grades (UNS S42000, EN 1.4021), standards (ASTM A276, ASTM A193, ASTM A182, ASME SA276, ASME SA193, ASME SA182), and applications.
AISI 420 (UNS S42000 / EN 1.4021) Stainless Steel is a high-carbon martensitic grade, primarily known for its ability to achieve *very high hardness* and strength after appropriate heat treatment (quenching and tempering). It offers good wear resistance and moderate corrosion resistance in mild atmospheric environments, fresh water, and some mild chemical exposures, especially when polished and hardened. It is magnetic in all conditions. As an AISI 420 Manufacturer, we ensure these properties in every bar we supply, adhering to standards like DIN 17440 420 and JIS SUS420.
AISI 420 is similar to AISI 410 but contains a *higher carbon content* (typically 0.15-0.40% for 420 vs. 0.08-0.15% for 410). This increased carbon allows 420 to achieve significantly *higher hardness* and strength after heat treatment compared to 410, making it more suitable for applications requiring maximum wear resistance and sharp edges. While 410 offers good hardness, 420 surpasses it for critical cutting tools and components. AISI 420 is preferred for cutlery, surgical instruments, springs, and plastic molds where extreme hardness and good surface finish are paramount, and corrosion conditions are moderate. Our ASTM A276 420 Supplier recommends it for applications benefiting from its superior hardenability and wear resistance, making us a trusted UNS S42000 Supplier.
DIPTI Metal Industries, an established ASTM A276 420 Supplier and UNS S42000 Stockiest, supplies AISI 420 bars in various profiles including Round Bars, Square Bars, and Hexagonal Bars, as well as Rods. Finishes include Hot Rolled, Cold Drawn, Annealed, Quenched & Tempered (for hardened properties), and Bright Bars, catering to different mechanical property and surface quality requirements for demanding applications. We are a prominent 420 Round Bar Supplier and 420 Hex Bar Exporter, also offering ASME SA276 420 compliant products.
AISI 420 (UNS S42000) is widely recognized globally. Key equivalents include EN 1.4021 (Europe), X20Cr13 (Germany/EN), 420S29 (UK), Z20C13 (France), and SUS 420 (Japan). It adheres to specifications like ASTM A276, ASTM A193 (for Grade B6X fasteners, though less common than B6), ASTM A182 (for F6NM forgings, which is a modified version), ASME SA276, ASME SA193, ASME SA182, EN 10088-3, DIN 17440, BS 970, NF A35-573, JIS G4303, GB/T 1220, GOST 5632, UNI 6900, and AS 1449, ensuring global compliance from an EN 1.4021 Manufacturer and ASTM A276 420 Exporter.
