S32520

S32520 duplex stainless steel is a kind of molybdenum, under low stress has good resistance to chloride stress corrosion performance. S32520

Stainless steel in 60 degree C above neutral chloride solution are prone to stress corrosion cracking, such in trace chloride and hydrogen sulfide industry was made in stainless steel heat exchanger, evaporator and other equipment are the tendency of stress corrosion cracking, and duplex stainless steel has good resistance ability.

S32520 stainless steel application:
S32520 Stainless steel won't produce corrosion, pitting, corrosion or wear and tear. Stainless steel or building one of the highest strength of metal materials in the material. Because the stainless steel has good corrosion resistance, so it can make structure parts permanently maintain the integrity of engineering design. Chromium stainless steel also has high mechanical strength and extensibility, easy processing and manufacturing of parts and can meet the needs of architects and structural designers.
