The stainless steel coil has the ability to withstand general corrosion similar to the unstable nichrome 304. Prolonged heating in the temperature range of chromium carbide may affect alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, high temperature applications require strong sensitization of materials to prevent intergranular corrosion at lower temperatures.

　　High temperature oxidation resistance

　　Although the news of limited production is constant, the steel output has not decreased. According to the latest data released by the Bureau of Statistics, in June 2019, China's crude steel output increased by 10% year-on-year to 87.53 million tons; steel output increased by 12.6% year-on-year to reach 10.71 million tons. It can be seen that the overall production limit effect in June is not satisfactory.

　　In the eyes of the industry, the news of limited production began to ferment at the end of June and is still continuing. In September, the military parade approached. In order to ensure the "parade blue", environmental pressure will increase, and subsequent restrictions on production are expected to be strong. It is expected that steel production will begin to fall in July and supply pressure will ease.

　　Stainless steel coils have high temperature oxidation resistance, but the oxidation rate is affected by inherent factors such as the exposed environment and product morphology.
