Bent tempered steel glass
Category: Tempered glass
Tempered glass is produced by first cutting ordinary annealed glass into the desired dimensions, then heating it to around 700°C—close to its softening point—and subsequently cooling it rapidly and uniformly. (Typically, 5–6 mm-thick glass is heated at 700°C for about 240 seconds, followed by a cooling period of roughly 150 seconds. For 8–10 mm-thick glass, the heating process lasts approximately 500 seconds at 700°C, with a cooling phase of about 300 seconds. In general, the heating and cooling times vary depending on the glass thickness.) After tempering, a uniform compressive stress forms on the glass surface, while tensile stress develops internally, significantly enhancing the glass's resistance to bending and impact. As a result, tempered glass boasts a strength that is more than four times greater than that of ordinary annealed glass. However, once glass has been fully tempered, it can no longer undergo any further processing, such as cutting or grinding, nor can it sustain damage. Otherwise, disrupting the balanced compressive stress could cause the glass to shatter completely into tiny fragments.
