440c stainless steel bar stock
440C stainless steel in round bar, diameters. 440C grade provides good wear resistance combined with moderate corrosion resistance in mild environments and has excellent hardenability. It can achieve a hardness of up to 60 Rockwell HRc. It resists corrosion in normal domestic environments and very mild industrial environments, with optimum corrosion resistance achieved with a temper below about 400°C. To achieve best corrosion resistance, surfaces must be free of scale, lubricants, foreign particles, and coatings applied for drawing and heading. With its high carbon content 440C annealed stainless machines similar to a high speed steel annealed grade

Diameters can be sawn to your required lengths as one offs or multiple cut pieces. 440C precision ground steel bar can be supplied, providing a high quality stainless steel ground bar to your required tolerances.
| Applications | Suitable for applications requiring a combination of excellent wear resistance with moderate corrosion resistance, 440C is commonly used in the oil and gas, marine, food and medical industries. Typical applications are pumps, valve components, bearings, knives, surgical tools, cutlery, bearings and races. |
| Forging | 440C stainless steel can be forged by heating slowly and uniformly to 1050-1150°C, allowing sufficient time for the steel to become heated through. Ensure not to overheat as this can cause a loss of toughness and ductility. Do not forge below 900°C reheating if necessary. After forging cool slowly in furnace or thermoinsulating material, then anneal immediately. Air cooling after forging may cause cracking. |
| Annealing | To anneal 440C stainless steel, heat uniformly to 840-875°C. Soak and cool very slowly in the furnace. |
| Hardening | To harden stainless steel 440C heat to 1010-1070°C, fully soak and quench in warm oil or air cool. Be careful not to overheat or full hardness will not be obtained. |
| Tempering |
When tempering 440C a Rockwell hardness of 60HRc can be obtained. Temper for at least one hour. Tempering above 400°C is not recommended as this can cause a reduction in corrosion resistance and impact properties.
|
| Heat Treatment | Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each stainless steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of 440C stainless steel. |
