7、JAN74(R) SINTERED TOOL MATERIALSForewordThis Document has also changed to comply with the new SAE Technical Standards Board Format.1. ScopeThis SAE Recommended Practice covers the identification and classification of ceramic, sinteredcarbide, and other cermet tool products.Its purpose is to provide
8、a standard method for designating the characteristics and properties of sintered toolmaterials.2. References2.1 Applicable PublicationsThe following publications form a part of the specification to the extent specifiedherein.

Suffix Requirementswhich provide quantitative values for the properties or characteristics of aspecific material.NOTEOnly
11、 pertinent properties or characteristics should be included. Alpha-numberic combinations whichdescribe commercially unavailable products must be avoided.Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-
12、SAE J1072 Revised FEB77-2-4. Basic ClassificationA sequence of five digits is used to type each sintered tool product. The first digitindicates the type of compound. The second digit indicates the binder metal. The third digit indicates thepredominating base metal, while the fourth and fifth digits
13、indicate other base metals. See Table 1.Example:SAE J1072 23200tungsten carbide with a cobalt binderSAE J1072 30600aluminum oxide ceramicSAE J1072 23234tungsten, titanium, tantalum carbide with a cobalt binder5. Suffix RequirementsA letter designating the property or characteristic to be specified i
14、s followed bynumbers which designate the level of the property or characteristic. (Note: Suffix Z shall be used to describeany property or characteristic for which an appropriate suffix letter has not been assigned.)5.1 Suffix ABinder Metal QuantityA three-digit number following the letter “A“ desig
15、nates the specifiedpercentage by weight of binder metal to the nearest 0.1%. The product range shall be 5% of the specifiedquantity.Example: A045 specifies 4.5% of binder metal described by the basic classification or a product range of 4.34.7%.5.2 Suffix BBase Metal QuantityA three-digit number fol
16、lowing the letter “B“ designates the specifiedpercentage by weight of base metal to the nearest 0.1%. The product range shall be 5% of the specifiedquantity. Each base metal described by the fourth and fifth digits of the basic classification shall be included.Example: B096B047 specifies 9.6% of bas
17、e metal described by the fourth digit of the basic classification and4.7% of base metal described by the fifth digit of the basic classification. The product ranges would be 9.110.1% and 4.54.9%, respectively.NOTEThe Basic Classification provides for two base metals other than the predominating base
18、 metal. Anyadditional base metal and its quantity must be described by suffix Z.5.3 Suffix CHardness per SAE J439A three-digit number following the letter “C“ designates the specifiedRockwell A hardness to the nearest 0.1 Rockwell A. The hardness range of the product shall be 0.3 RockwellA for produ
19、cts specified 89.9 Rockwell A or softer and 0.2 Rockwell A for products specified 90.0 Rockwell Aor harder.Example: C922 specifies 92.2 Rockwell A or a product hardness range of 92.092.4 Rockwell A.TABLE 1BASIC CLASSIFICATIONMaterial Compound Binder Metal Base Metal1-Nitride 0-None 0-None2-Carbide 1

21、HS-,-SAE J1072 Revised FEB77-3-5.4 Suffix DSpecific Gravity per SAE J439A three-digit number following the letter “D“ designates thespecified specific gravity or density in g/cm3 to the nearest 0.1 g/cm3. The density range of the product shallbe 0.1 g/cm3 from that specified.Example: D126 specifies
22、a density of 12.6 g/cm3 and a product density range of 12.512.7 g/cm3.5.5 Suffix EGrain Size per SAE J439One to three digits following the letter “E“ designate the specified grainsize.Example: A grain size rating of 231 per SAE J439 shall be specified E231.5.6 Suffix FApparent Porosity per SAE J439T
23、hree digits following the letter “F“ specify the maximumamount of each type porosity allowable, as depicted by the photographs of SAE J439. The first digit indicatesthe amount of type A porosity, the second digit indicates the amount of type B porosity, and the third digit theamount of type C porosi
24、ty.Example: F421 specifies a maximum apparent porosity rating of A-4, B-2, and C-1.5.7 Suffix GTransverse Rupture Strength per ASTM B 406A three-digit number following the letter “G“designates the specified minimum transverse rupture strength in psi x 1000 (MPa x 6.9).Example: G095 specifies a minim
25、um transverse rupture strength of 95,000 psi (656 MPa).5.8 Suffix ZOther PropertiesProperties not described by listed suffix designations and those which requiremore explicit description shall be written out.Examples:Z1thermal expansion from room temperature to 1500 F (816 C) shall be 3.46 x 10-6/F
