1 Stainless steel angle steel is widely used in the construction layout, as well as in various engineering layouts, such as the construction of beams, and has a significant effect in the construction of engineering equipment. 2. When used, stainless steel angle steel has comparative weldability, strong plasticity and deformation, and also has certain mechanical strength. 3. The corrosion resistance of stainless steel angle steel is relatively high, and it has good corrosion resistance in the production process of pulp and paper. Moreover, stainless steel is also resistant to the corrosion of ocean and corrosive industrial atmosphere. 4. Stainless steel angle steel can be used as equipment for dry pulp and paper making, heat exchanger, dyeing equipment, film processing equipment, pipes, and materials for the exterior of buildings in coastal areas. 5. Precipitation hardening stainless steel angle steel is a steel that can precipitate carbides in the steel by means of heat treatment, so as to improve the strength. 6. Martensitic stainless steel angle steel is a kind of steel whose properties can be adjusted by means of heat treatment. Its strength and hardness are high and it is very useful in technology and mechanics.
