| Description: The AP4 grade is less easy to turn than the other grades of ARCAP. It can however be machined without more difficulty than the nickel chromium molybdenum steels. High Corrosion Resistance: ARCAP alloys are very corrosion resistant to the majority of chemical and physical environments. CLAL can provide data for the corrosion resistance of ARCAP alloys. In particular ARCAP alloys have a very high resistance to scaling and clogging of pipes by hard water and the blocking of pipes used for transport powder products such as sodium aluminate, cement, etc. High Mechanical Properties: In annealed temper ARCAP, alloys have an elongation up to 45 %, which allows deep drawing. In spring temper the ultimate tensile strength is above 800 MPa. Non-Magnetic: A detector sensitive to 1/10 of nanotesla, placed at less than 1 mm from ARCAP alloys will not show any magnetic interference. This non magnetism is kept even at very low temperatures (measured at 4.2° k). Stable Resistivity: Temperature variations have almost no effect on the resistivity of ARCAP alloys. The temperature coefficient of the grade AP4 is 4 x 10-5/°C and 25 x 10-5/°C for the other grades. Excellent Behaviour At Low Temperature: At low temperatures the mechanical properties of ARCAP alloys are improved. A cryogenic application shows that the ultimate tensile strength and the yield strength increase without any diminution of the elongation or the impact strength. Very Easy To Process: ARCAP alloys are easily processed whether by forging, stamping, deep drawing, machining, welding or brazing. They are also easily plated. Information provided by CLAL-MSX |
