Stainless Steel Round Bars JIS SUS440C Straight Cut Lengths Rods
Stainless Steel - Grade AISI 440C (UNS S44004), JIS SUS440C, EN 1.4125, DIN X105CrMo17
Carbon: 0.95-1.25% This increases hardenability and wear resistance, but decreases toughness in higher amounts.
Manganese: max. 1.00% This is added to reduce brittleness and improve forgeability, hardenability, and reducing deformation.
Silicon: max. 1.00% This is a deoxidizer and improves hot-forming properties.
Chromium: 16.00-18.00% Added only to high alloy tool steels, this improves hardenability, high wear
resistance, toughness, and corrosion resistance.
Molybdenum: max. 0.75% Improves deep hardening and toughness.
In stainless grade 440 group, there have 440A, 440B and 440C.
| Grade | C | Cr | Mo |
| 440A | 0.60~0.75 | 16.00~18.00 | 0.75 max. |
| 440B | 0.75~0.95 | 16.00~18.00 | 0.75 max. |
| 440C | 0.95~1.20 | 16.00~18.00 | 0.75 max. |
All three of these stainless steels have the same amount of chromium, from 16 to 18 percent.
They are all high carbon high chromium martensitic standard stainless steels.
All of their other alloy elements are about the same, including manganese, silicon, phosphorus, sulfur, and molybdenum.
Truly, the difference in these three is the carbon content, which is substantial.
The higher carbon content in 440C yields a much more wear resistant knife blade.
440A: this is a hardenable stainless steel alloy, hardenable to a higher hardness than 420 series stainless steels
(which are only hardenable to 53 HRC). 440A has good corrosion resistance, and is used in less
expensive bearings and in harder surgical tools (rare). It has 0.60 to 0.75 percent carbon, about the same
carbon content as most steel springs.
Its advantage is that is cheaper than 440B, 440C and slightly more corrosion resistant.
440B: this is a hardenable stainless steel alloy, hardenable to a higher hardness than 440A.
It has good corrosion resistance and is used in cutlery (economy), valves, and instrument bearings, where high
wear is less important than high corrosion resistance. It has 0.75 to 0.95 percent carbon.
440C: this is also a hardenable stainless steel alloy, hardenable to a higher hardness than 440B.
It has good corrosion resistance, and is used in ball bearing balls and races, high pressure nozzles, valve seats
and high wear components. It has 0.95 to 1.20 percent carbon.
As detailed in the Machinery's Handbook: "This steel has the greatest quenched hardness and wear resistance
upon heat treatment of any corrosion-resistant or heat-resistant steel."
