The slow cooling process from ambient to cryogenic temperatures is important in avoiding thermal stress.  \n\nThe metal part is then held at a temperature of around −190 °C (−310 °F) for 20 to 24 hours before heat tempering takes the temperature up to around +149 °C (+300° F).\n\nThis heat tempering stage is critical in reducing any brittleness that may be caused due to the formation of martensite during the cryogenic treatment process.\n\nCryogenic treatment changes the entire structure of a metal, not just surface. So the benefits are not lost as a result of further processing, such as grinding.","shipping_methods":[{"name":"7-ELEVEN取貨付款","fee":0,"currency":"TWD"},{"name":"萊爾富取貨付款","fee":0,"currency":"TWD"},{"name":"宅配/貨運","fee":0,"currency":"TWD"},{"name":"7-ELEVEN取貨不付款","fee":0,"currency":"TWD"}],"lowest_shipping_fee":null,"payment_methods":["ATM轉帳","萊爾富取貨付款","7-ELEVEN取貨付款"],"category_id":"2092080393","category_name":"料理刀具/砧板","breadcrumb":[{"id":"24198","name":"居家、家具與園藝","url":"/tw/%E5%B1%85%E5%AE%B6%E3%80%81%E5%AE%B6%E5%85%B7%E8%88%87%E5%9C%92%E8%97%9D-24198-category.html"},{"id":"2092080373","name":"廚房鍋具/餐具/用品","url":"/tw/%E5%BB%9A%E6%88%BF%E9%8D%8B%E5%85%B7-%E9%A4%90%E5%85%B7-%E7%94%A8%E5%93%81-2092080373-category.html"},{"id":"2092080393","name":"料理刀具/砧板","url":"/tw/%E6%96%99%E7%90%86%E5%88%80%E5%85%B7-%E7%A0%A7%E6%9D%BF-2092080393-category.html"}],"view_count":1,"watch_count":6,"hashtags":["牛刀"]}
