Corrosion resistance of HASTELLOYB2 nickel alloy

Corrosion resistance of hastelloy b2

hastelloy b2 The strength indexes of nickel base alloy tee, nickel base alloy elbow, nickel base alloy reducer and nickel base alloy flanging steel include the specified non proportional elongation stress, yield point, tensile strength, etc. The tensile test is generally conducted on the testing machine. Before the test, measure the diameter (or thickness, width) of the sample, set the gauge distance, and then install the sample on the chuck of the testing machine. Nickel is added to make the alloy have pitting corrosion and crevice corrosion caused by milk and water containing lv compounds. Alloy 625 is a Kangpilao material with very high performance. Alloy 625lcf is a modified steel of 625 and has the performance required by bellows. The difference is that it has excellent low cycle fatigue resistance and thermal fatigue performance, which is the same as alloy 600. The phenomenon of "negative" deviation is out of line. The area of residential buildings for sale has decreased by 21. The alloy is light red or similar to pig iron, and it is resistant to gases containing lv, alloys, and alloy materials. Where the alloy is available, it has the ability to deliver goods in time, roll on demand, and cut on demand, so as to ensure that bao can provide users with qualified gao duan products accurately and quickly.

In the transient fracture zone, there is also a certain degree of creep damage. hastelloy b2 For the sample after fracture, the [0 orientation fracture is almost perpendicular to the stress axis, and the γ phase forms a raft along the direction perpendicular to the stress axis, which is prone to multiple slip on different slip planes; The fracture of [0 orientation is not smooth, and the γ phase forms a raft along the direction 45 ° to the stress axis, which is easy to start the sliding system of the same family; [1The orientation fracture is uneven and has no obvious raft direction, which is prone to multi system slip and cross slip between different groups of slip systems. hastelloy b2 For [0 and [0 oriented alloys, the secondary cracks are easy to expand along the raft direction, while for [1 oriented alloys, the secondary cracks are easy to form at the interface where the crack growth planes intersect and expand along a certain growth plane. hastelloy b2
