Use of SA203 GrD cryogenic vessel plate

SA203 GrD steel plate belongs to ultra-low temperature vessel plate, which is a kind of low-nickel alloy steel plate. SA203 GrD steel plate is divided into five grades: A, B, D, E, F. Because the nominal nickel content of the three grades of D, E, F is 3.5%, it is commonly known as 3.5Ni steel. SA203 GrD steel plate has good impact toughness and mechanical properties under low temperature conditions.

Delivery status and production process of SA203 GrD steel plate:
Delivery status: normalized, normalized + tempered, quenched and tempered.
Production process: heat treatment, SA203 steel is killed steel.

Detailed specification of SA203 GrD cryogenic vessel plate:
Thickness: 8-110mm, width: 1600-4020mm, length: 6000-18800mm.

SA203 GrD cryogenic vessel plate can be used in low temperature environment of -70℃~-101℃ (adjusted to -107℃), and is often used in cryogenic separation processing, air separation, liquefied gas storage, coal chemical industry and other industries to manufacture CO2 absorption tower, H2S absorption tower, methanol washing tower and other equipment.
