Condition: Cold rolled(drawn)≤50mm, Hot rolled≤12-250mm, Hot forged≥50mm.   AISI 4140/DIN 1.7225 Introduction: AISI 4140 alloy steel is chromium, molybdenum, manganese containing low alloy steel. It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength.   Fabrication and Heat Treatment: 1. Forging Preheat the steel carefully, then raise the temperature to 1150-1200°C for forging. Do not forge below 850°C. 2. Annealing Heat the AISI 4140 slowly to 800-850°C and allow enough time for the steel to be thoroughly heated. Cool slowly in the furnace to 480°C followed by air cooling. 3. Stress Relieving When parts are heavily machined, ground or otherwise subject to cold work, stress relieving will be beneficial prior to hardening. 4. Hardening AISI 4140 steel is usually supplied ready heat treated to 18-22HRC. If further heat treatment is required annealed AISI 4140 should be heated slowly to 840- 875°C and after adequate soaking at this temperature quench in oil. Temper as soon as the tools reach room temperature. 5. Tempering Heat the AISI 4140 carefully to a suitable temperature selected by reference to a tempering chart or table (usually between 550-700°C, soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in air. Tempering between 250-375°C is not advised as tempering within this range will seriously reduce the impact value. 6.

Ozone is a pale blue gas with a distinctively pungent smell. Ozone gas is a powerful oxidant and has many industrial and consumer applications related to oxidation. This same high oxidising potential, however, causes ozone to damage mucous and respiratory tissues in animals, and also tissues in plants, above concentrations of about 100 ppb. This makes ozone a potent respiratory hazard and pollutant near ground level. Ozone gas odour is sharp, reminiscent of chlorine, and detectable by many people at concentrations of as little as 10ppb in air.
