3、arbon steel sheet suitable for cold forming. WSS-M1A356-A1 CQ WSS-M1A356-A2 DQ WSS-M1A356-A3 DDQ Specification WSS-M1P94-A shall be used where pre-coating by the steel supplier is required. 2. APPLICATION These specifications were released originally for automotive body and chassis parts. A range of

4、 formability exists between Variants A1 through A3. Variant A1 is used for simple to form parts, i.e., brackets. Variants A2 and A3 are used for higher formability applications, coated or uncoated. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part produce

5、rs must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 CHEMICAL COMPOSITION (WEIGHT PERCENT) The upper and lower limits of chemical composition of the controlled elements shall be established by the supplier and be included in the control plan.

Acceptance of subsequent orders by the steel supplier for a given component at the agreed upon quality level implies that all steel supplied will be of a comparable quality level and will form that part satisfactorily as defined by the m

10、anufacturing activity. Ford Motor Company may, at its option and in agreement with the steel supplier, compile a list of property requirements such as mechanical properties, forming characteristics and surface texture, for each specific part. This list will be a mandatory extension of these specific
