摘要:
Method for producing shaped elements from sheet steel galvanized on one or both sides, the raw material being a galvanized steel strip, wherein at least one of the method steps is a transporting operation and wherein protection against "black spot corrosion" is achieved by applying an anticorrosive oil which contains N-acyl derivatives of sarcosine acid as a corrosion inhibitor.
摘要:
The invention relates to a method for producing molded bodies from sheet steel galvanized on one or both sides starting from galvanized steel strip, wherein at least one of the method steps is a transport process, and wherein an anti-corrosion oil containing at least one phosphoric acid polyoxyalkylene ester is applied to protect against "black spot corrosion."
