The material selection of liquid nitrogen storage tanks is crucial, because the storage conditions of liquid nitrogen are extremely harsh, requiring the material to maintain good performance at extremely low temperatures. The following is an explanation of the two materials s30408 ​​and Q245R:

S30408 ​​stainless steel
S30408 ​​is an austenitic stainless steel that can maintain its good plasticity and toughness in a low temperature environment. This stainless steel has excellent corrosion resistance and can resist the corrosion of impurities that may be contained in liquid nitrogen. S30408 ​​stainless steel has good welding performance and is suitable for the manufacture of liquid nitrogen storage tanks that require welding. Suitable for food-grade liquid nitrogen storage and occasions requiring cleanliness and corrosion resistance.

Q245R steel plate
Q245R is a carbon steel commonly used in pressure vessels with good strength and toughness.
Compared with stainless steel, Q245R steel plate has a lower cost and is suitable for projects with limited budgets.
Q245R steel plate has good processing performance and can be processed by welding, bending, etc.
Suitable for the manufacture of liquid nitrogen storage tanks that are cost-sensitive and whose operating conditions are not particularly harsh.
