Air hardenable shock-resistant steel alloys, methods of making the alloys, and articles including the alloys |
| abstract |
Carbon of from 0.18 to 0.26; 3.50 to 4.00 nickel; 1.60 to 2.00 chromium; 0 to 0.50 molybdenum; Manganese from 0.80 to 1.20; 0.25 to 0.45 silicon; 0 to less than 0.005 titanium; 0 to less than 0.020; 0 to 0.005 of boron; Sulfur from 0 to 0.003; iron; And an air hardenable steel alloy containing impurities in weight percent. Air hardenable steel alloys have a Brinell hardness in the range of 352 HBW to 460 HBW. Air hardenable steel alloys have high strength, medium hardness and toughness compared to any known air hardenable steel alloys and can be applied in applications such as steel sheaths, explosion-proof covers, explosion-proof V- Vulnerable parts, and explosion protection enclosures. |
