摘要:
A corrosion resistant alloy is provided having as essential elements about 0.8 to 1.2% carbon, 1 to 2.2% silicon, 0.4 to 10% manganese, 23 to 35% chromium, 2.5 to 11% tungsten, 1 to 4% molybdenum and the balance essentially iron. Other elements may be optionally present, such as up to about 2% each of cobalt, nickel, niobium, tantalum, vanadium, titanium, up to about 1% aluminum, up to about 0.1% boron, up to about 1% nitrogen, up to about 4% copper, rhenium in amounts of up to about 30% of the tungsten content, and up to about 3% of misch metal.
摘要:
A very high carbon, high vanadium alloy steel is prepared in which there is a specific relationship between carbon and vanadium, said steel containing chromium and molybdenum levels, together with balanced carbon and vanadium contents, so as to render said steel forgeable. Forged articles made from said steel after heat treatment to a hardness of 59 to 67 Rockwell C are highly resistant to abrasion and are suitable for a wide variety of uses where a wear resistant steel is required and conventional manufacturing techniques are employed.
摘要:
A low alloy steel which utilizes boron as an essential alloying ingredient. The boron controls and manipulates the fragment mass distribution characteristics of alloy steels used in fabricating explosive warheads.
