Sus430/430 Stainless Steel Features

sus430/430 stainless steel features

First, sus430 material introduction:

sus430 has the characteristics of corrosion resistance, mechanical properties and thermal conductivity, but it is brittle at room temperature and has stainless property in the atmosphere, water evaporator and other media, but the stainless property is insufficient when the medium contains high chloride ions. It has good corrosion resistance in oxidizing acid solutions, especially in dilute HNO3. Thin HNO3 related parts can be made. It can also make oxidation resistant parts below 900 degrees, scatters, furnace parts, oil nozzles, etc. Because its brittle transition temperature is above room temperature and sensitive to notch, it is not suitable for making parts of load bearing equipment below room temperature.

Second, sus430 applications and features:

sus430 is mainly used for the production of HNO3 chemical equipment, such as absorption tower, heat exchanger, storage tank, etc., thin plate is mainly used for building materials, daily necessities, automotive decorations, etc., for oxidation resistant parts below 900 degrees, scatter, furnace parts, oil nozzles, etc.
