随着低温压力容器的应用范围日益扩大,低温压力容器用钢锻件也正在逐步走向专门化。美国有SA350《要求缺口韧性试验的管道元件用碳素钢和低合金钢锻件》、SA522《低温用锻制或轧制含8%及9%镍合金钢法兰、管件阀门及零件》和SA765《压力容器元件用要求一定韧性的碳素钢和低合金钢锻件》等专用标准。日本有JISG3205《低温压力容器用碳素钢和低合金钢锻件》专用标准。英国在BS1503《承压用钢的锻制品(含锻制半成品)》中用专门的条款对低温用钢锻件提出特殊要求。国际标准ISO 2604/I《承压钢材—技术要求第一部分·锻件》也用专门章节对低温压力容器用钢锻
With the growing range of low temperature pressure vessel applications, low temperature pressure vessel steel forgings are gradually becoming specialized. The United States has SA350 “carbon steel and low alloy steel for pipe fittings requiring notch toughness test”, SA522 “forged or rolled with 8% and 9% nickel alloy steel flanges, pipe valves and parts” and SA765 “Pressure vessel components require a certain toughness of carbon steel and low alloy steel forgings” and other special standards. Japan has JISG3205 “low temperature pressure vessel carbon steel and low alloy steel forgings” special standards. The United Kingdom in the BS1503 “forged steel products (including semi-finished products forged)” with special terms for low-temperature steel forgings made special requirements. International Standard ISO 2604 / I “pressure steel - the first part of the technical requirements forgings” also used a special chapter on low temperature pressure vessel steel forging
