440C Stainless Steel Bar: Hardenable, Wear-Resistant & Supplier Guide

Why Choose 440c stainless steel bar?

440c stainless steel bar is a high-carbon martensitic stainless bar that can be through-hardened to very high hardness (up to about 58-60 HRC) while retaining good corrosion resistance and a fine, polishable edge, produced as round, square, flat and hexagon bar for ball bearings, valve seats, surgical and dental instruments, cutlery, nozzles, measuring tools and precision machine parts where a hard, wear-resistant and corrosion-resistant surface is essential. As a direct mill-source supplier, Huaxiao Stainless stocks 100,000 tons of stainless material and ships in as little as 15 days, all with ISO 9001 / IATF 16949 (TS16949) certification and full mill test reports.

Specifications, Sizes & Surface Finish

We supply 440c stainless steel bar to ASTM, AISI, EN and JIS standards. Common grades include 440C (1.4125, UNS S44004), a high-carbon martensitic grade that can be through-hardened to very high hardness with excellent wear and abrasion resistance, also available as 440A (1.4109) and 440B (1.4112) with slightly lower carbon for more toughness. Standard dimensions cover the full commercial range, and we offer surface finishes such as 2B, BA, No.4, HL and mirror polish. Custom sizes, tolerances and edge treatments are available on request for project-specific requirements.

Price Factors You Should Know

The 440c stainless steel bar price per kg is driven by grade, thickness, surface finish, order volume and raw-material nickel indices. Buying directly from a mill-source supplier removes distributor markups. For a current, volume-based quote, contact our sales team with your specification and destination port.
