JIS G3127 SL3N45 Introduce
JIS G3127, the Japanese Industrial Standard for cold-rolled steel products, is one of the most comprehensive and comprehensive standards in the world. It was established by the Japan Iron and Steel Federation (JISF) and applies to flat steel products such as strips, coils, and sheets used in various industrial applications. It includes not only standardized steel grades but also detailed information of required mechanical properties, manufacturing processes and product form for a range of applications.
Smelting temperature:1666°C - 1325°C
Application:Nickel steel plate for low temperature pressure vessel

JIS G3127 SL3N45 Material Machining Technology
{standards} steel is an alloy steel produced by the Japanese Industrial Standards (JIS) group. It is one of their most widely used grade of steel and its use has been increasing in recent years. This alloy steel is composed of chromium, tungsten, cobalt, and molybdenum as its primary alloying elements, with additions of vanadium, silicon, and nickel as well. The steel has a good combination of strength and toughness and is most often used to make automotive components, piping and storage vessels, military equipment, and general machining applications.
