SCOPE The materials defined by this specification are ferritic chromium rust resisting steels in the form of plate, sheet or strip. 2. APP

3、LICATION These materials are primarily intended for the manufacture of interior decorative trim mouldings and exterior moulding above the waistline level. As a general recommendation alloy A is for interior mouldings and alloy B for exterior mouldings. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR P

4、RODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 CHEMICAL COMPOSITION, % Alloy A Alloy B Carbon 0.10 max 0.10 max Chromium 15.5 - 18.0 18.0 - 22.0 Nickel 0.50 max 0.50 max Manganese 1.0 max 1.0

6、ble for forming the part without defects unacceptable to Product Development Group. Any additional requirement shall be specified on the Component Engineering drawing. 3.4 MATERIAL - AS RECEIVED FROM THE MILL 3.4.1 Surface Finish Material supplied to this specification shall be uniform in quality, c

7、lean, sound, smooth, not to exceed 0.25 m finish and free from defects detrimental to performance fabrication, corrosion resistance or appearance of the part for which it is intended. The surface quality shall be such that the material can be buffed to a finish and luster to meet visual acceptance s

8、tandards using a maximum of three buffing passes per standard procedure and using standard buffing equipment per FLTM EU-BQ 6-3, (FLTM BQ 6-3 may be substituted). The 0.25 m finish does not apply to areas where a special surface texture is specified. 3.4.2 Corrosion Resistance The material shall hav

9、e been given sufficient final pickling and passivation treatment to obtain an acceptable corrosion resistance. Material as received and given no further preparation shall not show signs of failure by red rust, pit corrosion or etching type corrosion in excess of that given below when subjected to 16

10、 hours CASS Test according to FLTM EU-BQ 5-1. Exterior parts 2 % max surface Interior parts 15 % max surface (Percentage corrosion attack is determined by grid method described in FLTM EU-BQ 5-1). 3.5 FINISHED PRODUCT - BRIGHT DECORATIVE FINISH 3.5.1 Surface Finish Finished products shall have been

11、buffed by an appropriate method to produce an acceptable surface finish and lustre as approved by the affected Engineering Design office. 3.5.2 Corrosion Resistance Significant surfaces of finished parts shall not show more than 2 % surface attack for exterior parts and 15 % maximum surface attack f

12、or interior parts as indicated by red rust, pits or etching type corrosion when subjected to 16 hours CASS test according to FLTM BQ 105-01. ENGINEERING MATERIAL SPECIFICATION SD-M1A9109-A/B Page 3 of 3 Copyright 2009, Ford Global Technologies, Inc. Significant surfaces are those surfaces which in a

13、ssembly are visible and subjected to wear and/or corrosion. Sheared or slit edges are excepted from “significant surfaces“ unless specifically noted on the drawing, in which case they are to be buffed. 3.6 FINISHED PRODUCTS - SPECIAL DECORATIVE SURFACE TEXTURES 3.6.1 Surface Texture The surface text

14、ure required shall be specified on the Engineering drawing. 3.6.2 Corrosion Resistance Parts receiving special decorative surface textures may require special processing (acid passivation or chrome plating) to ensure adequate corrosion protection. Significant surfaces of finished parts shall meet th

15、e corrosion resistance requirements as given in paragraph 3.5.2. 4. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of this specification. Material to specification SD-M1A9101-A may be used as an alternative for production released components but not for prototype components. Material compositions meeting this specification are BS 1449 Pt. 4 1967, 430S15 and 442S19, also X8 CR 17 DIN 17440.
