Key Features of AISI 420F Stainless Steel
Stainless Steel AISI 420F (UNS S42020 / EN 1.4029) is a free-machining martensitic stainless steel, developed to offer significantly improved machinability over standard 420, while retaining its excellent hardenability and wear resistance. Its specific chemical composition, including higher sulfur, allows for high-speed production of complex parts. As a leading AISI 420F Supplier and ASTM A276 420F Stockiest, we highlight its core benefits:
Excellent Free-Machinability
The increased sulfur content leads to excellent chip breakage and reduced tool wear, allowing for very high machining speeds and efficient production on automatic screw machines, from an expert AISI 420F Manufacturer.
Very High Hardness & Strength (Heat Treatable)
Can be hardened by quenching and tempering to achieve very high hardness (up to 50 HRC and beyond) and strength, making it suitable for cutting applications and wear-resistant parts, fulfilling requirements of an EN 1.4029 Exporter.
Good Wear Resistance
The high hardness achieved after heat treatment provides excellent resistance to abrasion and wear, extending the lifespan of components in demanding mechanical environments, meeting BS 970 420S37 standards.
Moderate Corrosion Resistance (in mild environments)
Offers good corrosion resistance to atmospheric exposure, fresh water, steam, and some mild chemicals, especially when in the hardened and polished condition. It is generally not recommended for severely corrosive environments due to higher sulfur, compliant with AFNOR Z20CMF13.
Magnetic Properties
Being a martensitic stainless steel, AISI 420F is magnetic in both the annealed and hardened states, which can be a key characteristic for certain electromechanical applications, from a reliable GOST 20Х13С Supplier.
Widely Accepted for Precision Machined Parts
A globally recognized and preferred grade for high-volume, precision-machined components requiring high hardness and wear resistance, ensuring wide compatibility, thanks to our global network as an AS 420F Exporter.

Stainless Steel ASTM A276 / AISI 420F Bars — Frequently Asked Questions
Find answers to common questions about AISI 420F Manufacturer production, grades (UNS S42020, EN 1.4029), standards (ASTM A276, ASTM A582, ASME SA276, ASME SA582), and applications.
AISI 420F (UNS S42020 / EN 1.4029) Stainless Steel is a free-machining martensitic grade, derived from standard 420 but with added sulfur to significantly improve machinability. It retains the ability to achieve *very high hardness* and strength after heat treatment (quenching and tempering), offering excellent wear resistance and moderate corrosion resistance in mild environments. The 'F' denotes Free-Machining, making it ideal for high-volume production on automatic screw machines. As an AISI 420F Manufacturer, we ensure these properties in every bar we supply, adhering to standards like DIN 17440 420F and JIS SUS420F.
The primary difference between AISI 420F and standard AISI 420 is the addition of sulfur in 420F (typically 0.15-0.35%). This significantly *improves machinability* by promoting brittle chip formation and reducing tool wear, making it suitable for automatic machining operations where high production rates are desired. While 420F retains high hardenability and wear resistance comparable to 420, the higher sulfur content *reduces its corrosion resistance and weldability*. Therefore, 420F is preferred for applications like valve components, fittings, and other intricate parts produced on screw machines, where the ease and speed of machining outweigh the need for maximum corrosion resistance or extensive welding. Our ASTM A276 420F Supplier recommends it for applications benefiting from its superior machinability, making us a trusted UNS S42020 Supplier.
DIPTI Metal Industries, an established ASTM A276 420F Supplier and UNS S42020 Stockiest, supplies AISI 420F 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, heavily machined applications. We are a prominent 420F Round Bar Supplier and 420F Hex Bar Exporter, also offering ASME SA276 420F compliant products.
AISI 420F (UNS S42020) is widely recognized globally. Key equivalents include EN 1.4029 (Europe, as X20CrMoS13 or similar), 420S37 (UK), Z20CMF13 (France), and SUS 420F (Japan). It adheres to specifications like ASTM A276, ASTM A582 (Free-Machining Stainless Steel Bars), ASME SA276, ASME SA582, 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 1.4029 Manufacturer and ASTM A276 420F Exporter.
