Scope

This standard specifies the requirements for the zinc plating layer on the steel treated. The contents of this standard contains the desired direction provided by electroplating production funding
Former material and plating, heat treatment requirements.
This standard does not apply to.
--- Unprocessed steel sheet forming, strip and wire zinc plating;
--- Tightly wound spring zinc plating;
--- Non-use of protective decorative zinc plating.
The standard does not specify requirements for electro-galvanized front surface state of the base metal, but the defects of the base metal surface of the film and have a look
It can be adversely affected.
The thickness of the plating layer on the threaded member can be threaded through the assembly level or size requirements to qualify.

Summary	This standard specifies the treated steel zinc plating layer requirements. This standard contains required orientation information provided by plating and electroplating before and after heat treatment requirements. This standard does not apply to: unprocessed shaped steel sheet, strip and wire zinc plating, tightly wound spring zinc plating, non- protective decorative purposes zinc plating. This standard does not specify the base metal before galvanized surface state requirements, but the surface of the base metal layer deficiencies in appearance and can adversely affect performance. Threaded member on the thickness of the plating layer may be level or assembly by a threaded size requirements to be qualified.
