Stainless 440C is a high-carbon martensitic stainless steel. As a martensitic stainless steel, 440C is magnetic and can be hardened by heat treatment. The high carbon content in 440C provides high hardness and strength. Despite this carbon content, the chromium content is sufficient to retain its stainless characteristics. 440C / S44004 / 1.4125 Martensitic Stainless Steel Ex The corrosion resistance of grade 440C/1.4125/4125 approximately matches that of grade 304 in many environments. 440C/1.4125/4125 Stainless Steel is used in a wide variety of industries including bearing manufacture, food applications, aerospace applications, surgical instruments, cutlery, etc.
Once heat-treated, 440C achieves the highest hardness and wear resistance of any stainless steel currently available. It is particularly suited to applications such as valve parts and bearings. Machinability. Alloy 440C is relatively easy to machine in the annealed condition. Machining of the alloy is much more difficult when hardened.

Leng TRW Safety Systems/Mesa, Mesa, AZ 85216 (USA) (Received June 3, 1993; Bal-tec - Stainless Steel Balls, Type 440C HardenedType 440C Stainless Steel is widely used in antifriction bearings, in valves and in many other applications where high hardness and reasonable corrosion resistance are required. This material is much more resistant to abrasion and wear than chrome steel. It is a high alloy, fine grain, through hardening, Martensitic stainless steel. Ball Bearing Steel:440C Vs. 52100 In A Corrosive Nov 01, 2010 · At Pacamor Kubar Bearings (PKB), we manufacture the vast majority of our miniature and instrument ball bearing rings from AISI 440C stainless steel, which is the standard material for most domestically manufactured miniature and instrument bearings for aerospace and medical applications.
Stainless Steel (AISI 440C) and Chrome Steel (SAE 52100) 440C stainless steel and 52100 chrome steel are the most common materials used in precision miniature and instrument ball bearings. AISI 440C is a hardened stainless steel suitable for any application that requires corrosion resistance at room to mid-hot temperature range. GCR15 Bearing Steel - NZ Miniature BearingsThe surfaces of the bearings must be protected with a coating of rust inhibitor or oil to stop oxidation. 440C Stainless Steel. Grade 440C stainless steels are high carbon steels, which attain the highest hardness, wear resistance and strength of all stainless steel grades after heat treatment. High Speed Steel 440C Tool Steel 440C SteelData Sheet - 440C. 440C is a hardenable chromium steel. It has one of the highest attainable hardnesses of the corrosion and heat resisting grades. This grade is magnetic at all times. For those applications where superior machinability is desired and where slightly lower corrosion resistance is satisfactory 440C can be supplied.
Dec 27, 1992 · Nucleation and growth of rolling contact failure of 440C bearing steel A 'two-body' elasto-plastic finite element model of 2-dimensional rolling and rolling-plus-sliding was developed to treat the effect of surface irregularities. The model consists of a smooth cylinder in contact with a semi-infinite half-space that is either smooth or fitted with one of 0.4 microns deep or 7 microns deep groove, or a 0.4 QUICK SHAFTS Solid - Stainless Steel, InchQBC has a large selection of Ball Bearing Inserts and other Ball Bearing Products, FREE CATALOG.

440C stainless steel suitable for bearings rings and rolling elements. Despite these advantages, however, there are some drawbacks to using 440C. The strength and wear resistance of 440C stainless steel is less than that of standard 52100 bearing steel. Load ratings of bearings made from 440C stainless steel are typically about thirty percent
