Chemical Industry

1. Environmental protection chemical industry:

The flue gas desulfurization device for thermal power generation: steel represents the grades 304, 1.4529, 254SMO, AL-6XN, 904L, C-276, C-22, C-2000, etc.)

Water treatment pipeline equipment: Monel alloy in Ni-Cu alloy has good mechanical properties and mechanical properties, is easy to press processing and cutting processing, and has good corrosion resistance. Mainly used for corrosion-resistant parts and equipment that work under high temperature loads. Hastelloy (OCr16Ni57Mo16Fe6W4) in Ni-Mo alloy can withstand all concentrations of hydrochloric acid and hydrofluoric acid at room temperature. Incor’s alloy (OCr15Ni57Fe) in Ni-Cr alloy has good mechanical properties and high oxidation resistance at high temperature. It is one of the few materials that can resist thermally concentrated MgCl2 and corrosion.

2. Petroleum and organic chemicals: chemical pipelines, heat exchangers, condensers, desulfurization and denitrification towers, pressure vessels, etc. In the chemical industry, equipment is an extremely important part. With the improvement of modern industrial technology, the special requirements for the strength, hardness, toughness, shaping, wear resistance, corrosion resistance and other production aspects of equipment and parts are getting higher and higher. Chemical machinery and equipment must be corrosion resistant. The use of these grades of stainless steel like 340L, 316L, 0Cr18Ni11Ti, 0Cr18Ni11Nb can prevent the amount of harmful effects caused by the precipitation of carbides during welding.

3. Food processing: Food grade stainless steel mainly includes 304 stainless steel and 316 stainless steel. 304 stainless steel can resist chemical corrosion and oxidation. The standard material of stainless steel pressure cooker is above 304. 316 stainless steel is better, contains 10% nickel, and is more corrosion-resistant. It is widely used in medical applications without metal ion precipitation and is very safe.

4. Fertilizer plant: urea steel 316LMod, etc.
