535A99 Through Hardening Steel
535A99 is a very high strength steel alloy that is hardened and tempered before supplying and has nickel, chromium, molybdenum making its high tensile steel strength, with good ductility and wear resistance. With relatively good impact properties at low temperatures, 535A99 is also suitable for a variety of elevated temperature applications. 535A99 round bars have good internal strength and high external strength, which makes them highly wear-resistant. 535A99 steel round bars offer a good combination of ductility, strength, and wear resistance. 535A99 is a very high-strength alloy engineering steel.

Applications
Applications for 535A99 steel include ejector pins, ball and roller bearings, gauges, taps and swaging dies. It is a good quality steel for wear resisting machine parts and for press tools which do not merit a more complex quality steel grade.
Analysis
| Carbon | 0.95-1.10% | Manganese | 0.40-0.70% |
| Chromium | 1.20-1.60% | Sulphur | 0.040% max |
| Silicon | 0.10-0.35% | Phosphorous | 0.035% max |
Forging
Heat the steel slowly and begin forging at 1000-1050°C. Allow sufficient time at the forging temperature for the component to be thoroughly soaked through. Re heat the component as necessary and do not forge below 850°C. After forging 535A99 furnace cool slowly.
Annealing
535A99 is commonly supplied in the annealed machineable condition. Re-annealing will only be necessary if the steel has been forged or hardened. To anneal, heat the 535A99 steel slowly to 800-810°C, soak well and allow furnace cool in the.
Stress Relieving
When parts are to be heavily machined, stress relieving will be beneficial prior to hardening. Heat the steel carefully to 700°C, soak well and allow to air cool.
Hardening
Heat slowly to the hardening temperature of 800-820°C. Maintain until thoroughly soaked through. Plenty of time must be given for this soaking, then oil quench.
Tampering
emper according to the purpose for which the tools are required, generally between 150°C and 300°C. Soak well at the selected temperature and soak for at least one hour per 25mm of total thickness. Air cool slowly.
