CRCA - Cold Rolled Close Annealed -

CRCA - Cold Rolled Close Annealed - This means that after hot rolling and storing, the steel is cold rolled to a reduced thickness which makes it fragile. This is then followed by annealing in a closed atmosphere of nitrogen gas that softens it and protects it from oxidation.

抽样调查-冷热轧密切退火-这意味着，经过热轧和存储，钢是冷轧到厚度减少，使它变得脆弱。这被接着一种封闭的软化它，保护它免受氧化氮气气氛中退火。

CRCA - 冷轧退火关闭 - 这意味着，热轧和存储之后，使钢冷轧到厚度减小，这使得它是脆弱的。这随后是退火软化，并从氧化保护它氮气密闭的气氛。

为冷轧退火-关闭-这意味着热轧后存储、钢冷轧厚度减小使它脆弱。接着是在一个封闭的大气氮气软化它，保护它免受氧化退火。
