Low-temperature structural steels are steels that are specially designed for low temperatures.These are steels that are used at temperatures between 0 ° C and -273 ° C.While the toughness of steels usually drops with falling temperatures,this effect is delayed by cold alloy steels through certain alloying elements and thus shifted to lower temperature ranges. results for this questionWhat is low carbon steel?What is low carbon steel?Low carbon,3.5%-nickel steels are often used in liquid gas storage tanks at temperatures down to -100°C.Many aluminium,nickel,and titanium alloys are also suitable for these temperatures.Aluminium 7076-T6 can also be used up to -128 °C,but not for critical applications.Metals and materials for low temperatures and cryogenic results for this questionWhat is tempered low alloy steel?What is tempered low alloy steel?These are mainly quenched and tempered low alloy steels.Almost all aluminium alloys can be used at temperatures down to -45 °C,except series such as 7075-T6 and 7178-T6,and titanium alloys 13V-11Cr-3Al or 8Mn.Copper and nickel alloys can generally all be used at these temperatures.Metals and materials for low temperatures and cryogenic
