aisi 420 stainless tool steel in round bar, flat bar and plate in full lengths or bandsaw cut.aisi 420 is a chromium alloyed stainless plastic mould steel, which is characterised by good polishability, good hardenability with high hardness achievable after heat treatment. The steel has fair corrosion resistance giving this plastic mould stainless steel grade suitability for applications requiring good hygiene in industries such as medical and optical.

aisi 420 steel round bar, flat bar and plate. Diameters can be sawn to your required lengths as one offs or multiple cut pieces. Rectangular pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar can be supplied, providing a quality precision finished bar to close tolerances. 

Applications

aisi 420 stainless steel is ideally suited for plastic moulds, acid aggressive plastics, PVC or acetates and can be used with plastics containing abrasive fillers.aisi 420 is suitable to produce components for medical and optical applications where a high surface finish is required.

Forging

aisi 420 plastic mould stainless steel can be forged by heating slowly and uniformly to 1000°C. After forging cool slowly in furnace or thermoinsulating material.
Annealing

aisi 420 is commonly supplied in the annealed condition. Re-annealing will only be necessary if the steel has been forged or hardened. To anneal heat slowly to 780°C. Cool slowly in furnace to 600°C and then cool in air.
Stress Relieving

When heavy machining or grinding of aisi 420 plastic mould stainless steel has been carried out it is advisable to stress relieve in order to minimise the danger of distortion or cracking during the subsequent heat treatment. To stress relieve, heat the tools slowly to 650°C, soak for a minimum of two hours per 25mm of section and allow to cool down in the furnace to 500°C then continue to cool freely in air. The tools can then be finish machined, leaving on an allowance for final grinding after hardening and tempering. 
Hardening

Pre heat the aisi 420 stainless steel to 600-700°C until heated through. Continue heating the aisi 420 to the final hardening temperature of 980-1050°C ensuring that the component is heated through. Protect the 420 component against decarburisation by using a neutral salt bath, controlled atmosphere furnace or vacuum. Air cool or quench in oil.
Tempering                 

  Heat uniformly and thoroughly to the selected tempering temperature and hold at heat for one hour per 25mm of total thickness. Double tempering is recommended. To achieve the best permutation of hardness, toughness and corrosion resistance it is recommended to temper at 250°C.

 

Temperature [°C] 100 200 300 400 500 600
Hardness [HRc] 56 54 52 54 53 34
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 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 aisi 420 stainless tool steel.
Final Grinding

Select the correct grade of wheel in consultation with the grinding wheel manufacturer. Ensure the grinding wheel is in good condition by means of a suitable dressing tool. Wet grinding is a preferable option using a copious supply of coolant. If dry grinding is resorted to then use a very soft wheel.
