JIS G3127 SL5N60 Introduce
The steels within the JIS G3127 standard resemble the Japanese Industrial Standards Nr15 and Nr17, as well as other JIS steel grades, but exhibit higher mechanical properties due to their alloyed composition. As a low alloyed steel, the steel composition of JIS G3127 SL5N60 is characterized by its reactivity and machinability. The steel strength is also suitable for many applications that require high strength such as truck frames and bridge construction.
Smelting temperature:1678°C - 1548°C
Application:Nickel steel plate for low temperature pressure vessel
