We are professional AMS 6418(AMS 6418F,HY-TUF,Hy Tuf)DTH Drilling Bits Button Bits Shank Borewell Bit Forged Forging Steel body Bodies from china

Composition: Shall conform to the following percentages by weight, determined by wet chemical methods in accordance with ASTM E350, by spectrographic methods in accordance with Federal Test Method Standard

No. 151, Method 112, or by other analytical methods approved by purchaser:

min max

carbon 0.23 - 0.28

Manganese 1.20 - 1.50

Silicon l. 30 - 1.70

Phosphorus -- 0,025

Sulfur -- 0.025

Chromium 0.20 - 0.40

Nickel 1.65 - 2.00

Molybdenum 0.35 - 0.45

Copper -- 0.35
AMS 6418 Shall be J45=24 min, determined on the standard end-quench test specimen in accordance with ASTM A255 except that the steel shall be normalized at 1725"F~25 (940"C~15) and the test specimen austenitizedat 1600"F + 25 (870"C~15). The hardenability test is not required on a product which will not yield a suitable specimen but the steel from which the product is made shall conform to the hardenability specified.

Properties After Heat Treatment: Product 2.50 in. (62,5 mm) and over in nominal diameter or distance between parallel sides shall have transverse tensile properties as specified in 3,3.5.1 after being heat treated as

follows: Normalize by heating to 1725"F~25 (940"C~15), holding at heat for 60 min. + 10, and cooling in air. Harden by heating to 1600"F + 25 (870°C + 15), holding at heat for 60min.~10, and quenching in oil at 120•- 140"F (50"- 60°C),Temper by heating to 550°F + 25 (290"C~15), holding at heat for2 - 3 hr, and cooling in air.
