The classification of stainless steel materials is often replaced by numbers such as SS201 and SS304. What are the specific characteristics of these materials? How should customers choose hose clamp materials? Let us do a solution.
Stainless steel 201 is a nickel-saving stainless steel, which has the characteristics of beautiful appearance and corrosion resistance, but does not have the characteristics of high temperature resistance.
Stainless steel 304 features: 304 stainless steel is a universal stainless steel material, and its anti-rust performance is stronger than that of 200 series stainless steel materials. The high temperature resistance is also better, and the general use temperature limit is less than 650℃. 304 stainless steel has excellent corrosion resistance and intergranular corrosion resistance. For oxidizing acids, it is found in experiments that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration below 65% boiling temperature. It also has good corrosion resistance to alkali solutions and most organic and inorganic acids.
Stainless steel 316 features: corrosion resistance is better than 304 stainless steel, and it has good corrosion resistance. Moreover, 316 stainless steel is also resistant to marine and aggressive industrial atmosphere.
316 stainless steel has good oxidation resistance in intermittent use below 871 °C (1600 F°) and continuous use below 927 °C (1700 F°).
