ASTM A314 Grade S20161 Introduce
ASTM A314 Grade S20161 is a type of steel specifically designed to provide enhanced corrosion and temperature resistance in comparison to more traditional steel grades. The combination of its low Thermal Expansion Coefficient and high Thermal Conductivity means it will have increased stability when exposed to high temperatures and provides greater resistance against thermal shock. The thermal properties of ASTM A314 Grade S20161 makes it a great choice for many applications, particularly those which require a material with enhanced resistance to high temperatures and extreme thermal fluctuation. This grade of steel has exceptional Isotropic Properties, allowing for greater strength and stability, and is capable of retaining its properties even when exposed to extreme heat. This makes it a valuable asset when looking for a material to stand up under harsher temperatures and conditions.
Smelting temperature:1551°C - 1373°C
Application:Specification for stainless steel and steel rods for forging and heat
