410 Martensitic Stainless Steel Bar410 is a basic straight chromium high hardenability martensitic stainless steel with good strength and fairly good corrosion resistance as generally supplied hardened and tempered in the tensile range 700 - 850 Mpa (condition R) Brinell range 201 - 255.Characterised by good corrosion resistance in mild atmospheric industrial and domestic environments coupled with good strength and excellent toughness in the hardened and tempered condition. 410 due to its excellent hardenability is capable of being through hardened to over Rc40 depending upon carbon content and section size. Small sections can be air cooled and larger sections oil quenched for maximum through hardness.Pre hardened and tempered 410 will also respond readily to nitriding achieving a typical surface hardness of over Rc65. The nitriding process however reduces the corrosion resistance and is therefore not generally recommended except for critical applications where the benefit outweighs all other considerations.
Used for parts requiring a combination of good strength and toughness, plus reasonable corrosion resistance. Typical applications are: Bolts, Bushings, Fasteners, Gas Turbine Parts, Mine Equipment, Pump Parts, Petrochemical Equipment, Steam Turbine Parts, Studs, Valve Parts etc.
Material magnetic in all conditions.

|Elevated Temperature Properties|
|410 displays good resistance to scaling in continuous service up to 650oC. Its use however at these higher working Temperatures results in a substantial drop in tensile strength and hardness with subsequent increase in ductility. |

|NB. Creep and stress rupture strength is also substantially reduced at these higher working temperatures.|
|Low Temperature Properties|
|410 is not recommended for use at sub-zero temperatures due to a substantial drop in impact properties consistent with most steels other than the austenitic steel types.|
|In the hardened and tempered as supplied condition, it will be more difficult due to the high yield strength which must be taken into account.|
|In the hardened and tempered as supplied condition, it is not recommended due to its affect on the mechanical properties within the heat affected zone. |
|410 has better corrosion resistance than 416 grade, but lower than 431 grade. Also lower than most of the 400 series ferritic stainless steels, and all of the 300 series austenitic stainless steels.NB. It has optimum corrosion resistance in the hardened and tempered condition and is not therefore recommended for use in the annealed condition. It is most important that oxygen is always allowed to circulate freely on all stainless steel surfaces to ensure that a chrome oxide film is always present to protect it. If this is not the case, rusting will occur as with other types of non stainless steels.For optimum corrosion resistance surfaces must be free of scale and foreign particles. |
Finished parts should be passivated.
|Heat uniformly to 1100oC - 1200oC, hold until temperature is uniform throughout the section. |
Do not soak but commence forging immediately.Do not overheat as this can cause a loss of toughness and ductility. Do not forge below 900oCFinished forgings should be cooled slowly in ashes or warm dry lime etc. until hand warm and annealed immediately.
|Heat uniformerly to 650oC - 750oC as required, hold until temperature is uniform throughout the section.*Soak as required, cool in air. Note: For best machinability use the low end of the range. |
|Heat uniformerly to 820oC - 900oC, hold until temperature is uniform throughout the section.*Soak as required. Cool in furnace.|
|Heat to 950oC - 1020oC, hold until temperature is uniform throughout the section. *Soak as required.Quench in oil or air cool. Temper immediately while still hand warm.|
|Prior to nitriding, the chrome oxide film which protects the surface must be broken down by pickling or fine sand blasting.Nitriding is carried out at 500oC - 550oC followed by slow cooling (no quench) reducing the problem of distortion. Parts can therefore be machined to near final size, leaving a grinding tolerance only. Always ensure that the tempering temperature employed during the initial heat treatment was higher than the nitriding temperature otherwise the core strength will be affected. |
|Tempering (Condition R)|
|Heat to 600oC - 700oC as required, hold until temperature is uniform throughout the section. *Soak as required.Cool in air. A double tempering treatment as follows is recommended for optimum toughness.Heat to 650oC - 680oC. *Soak as required. Cool in air |
Re-heat to 620oC - 660oC. *Soak as required. Cool in air
410 can of course be tempered at much lower temperatures, producing much higher tensile strengths, but with subsequent lower impact properties.
NB. Tempering however within the range 400oC - 580oC should be avoided due to temper brittleness, resulting in a considerable reduction in impact properties and loss of corrosion resistance.
*Heating temperatures, rate of heating, cooling and soaking times will vary due to factors such as work piece size/shape, also furnace type employed, quenching medium and work piece transfer facilities etc.
Please consult your heat treater for best results.
|410 machines best in the hardened and tempered as supplied condition R, and is regarded as being readily machineable with all operations such as turning, milling and reaming etc. capable of being carried out as per machine manufacturers recommendations for suitable tool type, feeds and speeds.It does not work harden to the same extent as the 300 series austenitic stainless steels, but is more similar in this respect to the low alloy high tensile steels such as 4140 etc.|
|Welding 410 in the hardened and tempered condition as supplied condition or in the annealed condition requires special attention due to its air hardening capability which can lead to the formation of brittle martensite, resulting in cold cracking due to contraction stresses within the weld and heat affected zone. Welding in the annealed condition can be beneficial in accommodating some of these contraction stresses in the base material when a high degree of restraint applies or with large sections. However problems can still occur. The higher the carbon content the higher the hardening capability and the greater the risk of cracking.Pre-heating and interpass temperature control during welding, plus very slow cooling and post-weld annealing is the best method to prevent cracking. The following welding procedure and post-weld heat treatment may be taken as a guide only. |
|Welding can be carried out using most of the standard welding processes.Welding electrodes or rods should be low hydrogen types 410 or *similar when strength is required or when post-weld hardening and tempering, otherwise an austenitic stainless electrode or rod such as 308 or *similar may be used to give a more ductile weld, when strength is not so critical and post-weld annealing is not possible or intended. Pre-heat at 200oC - 300oC and maintain a high heat input during welding. On completion of welding cool slowly as possible until hand warm and as required:Post-weld sub-critical anneal at 630oC - 680oC or full anneal and harden and temper as required. |
