Mostly a decorative coating. Only very limited corrosion protection under mild corrosion conditions. Materials qualified under MIL-DTL-81706 produce coatings that range in color from clear to iridescent yellow or brown. Inspection difficulties may arise with clear coatings because visual inspection does not reveal the presence of a coating. Type 1 Hexvalent Chromate Type II ROHS, Hex, Free Chromate No dimensional change. For moving parts which cannot tolerate the dimensional change of a more corrosion-resistant finish. For decorative applications and can be used to decrease light reflection. Alkaline oxidizing. For wrought iron, cast and malleable irons, plain carbon and low-alloy steel. Bright Corrosion protecting plating. Engineering Plating Type I Excellent hardness (Rc68-74), wear resistance and erosion resistance. Has low coefficient of friction, and is resistant to heat. In addition to the above properties, can be rendered porous for lubrication purposes. All Class 2 plated parts designed for unlimited life under dynamic loads shall be shot peened per SAE-AMS-S-13165 or Mil-R-81841 prior to plating. Plated to specified dimensions or processed to specified dimensions after plating. Parts below Rockwell C40 and subject to static loads or designed for limited life under dynamic loads. Parts below Rockwell C40 and designed for unlimited life under dynamic loads. Parts below Rockwell C40 or above and subject to static loads or designed for limited life under dynamic loads. Parts have hardness of Rockwell C40 or above and are designed for unlimited life under dynamic loads There is a nickel finish for almost any need. Nickel can be deposited soft or hard dull or bright, dependingon process used and conditions employed in plating. Thus, hardness can range from 150-500 Vickers. Corrosion resistance is a function of thickness. Has a low coefficient for thermal expansion—is magnetic. Intended to improve the corrosion resistance of parts made from austenitic, ferritic and martensitic corrosion-resistant series of the 200, 300, and 400 series and precipitation hardened corrosion-resistant steels. 440C grades may be exempt from passivation treatments at the discre- tion of the procuring activity. White matte to very bright in appearance. Good corrosion resistance, depending on base metal.Will tarnish easily. Hardness varies from about 90 Brinnel to about 135 Brinnel depending on process and plating conditions. Solderability is excellent, but decreases with age. Best electrical conductor. Has excellent lubricity and smear characteristics for anit-galling uses on static seals, bushings etc. Color is gray-white in a plated condition. Had very high luster in fused condition. Soft, but very ductile. Corrosion resistance good. Solderability is excellent. Tin is not good for low temperature applications (changes structure and loses adhesion when exposed to temperature below 40° F. To prevent zinc migration and poor solderability, during service or storage , brass or other copper alloys containing more than 5% zinc must have at least 0.0001” Copper underplate or 0.00005” Nickel underplate. Excellent Solderability. Either a matte or bright luster is acceptable. For electronic components, use only parts with a matte or blow brightened finish. Tin 50—70% by weight. This specification covers requirements for electrodeposited Zinc coatings applied to iron or steel articles to protect them from corrosion. High strength steels (tensile strength greater than 1700MPa) shall not be electroplated.
