High Pressure Fatigue Testing of 160 KSI Yield Strength

Aug 12, 2008 · High pressure processes like water-jet cutting, hydroforming or LDPE production require high pressure tubing with nominal sizes of 2 to 90 mm for pressures of up to 4,000 bar. The most common materials for these applications are either cold drawn austenitic steels type 304 / 316 or low alloy martensitic steels from the A723 series.

Yield-Before-Break Fracture Mechanics Analysis of High

Case study examples of fracture mechanics testing and analysis of Ni-Cr-Mo high strength steel cannon tubes are presented. The testing and analysis include the situation of significant plastic deformation accompanying fracture, which often occurs when high pressure is applied to high-toughness steel pressure vessels. analysis is based on a comparison of the size of the Irwin crack-tip plastic

Fracture Toughness of High-Strength Steels at Low

The effects of variations in composition on a series of Ni-Cr-Mo-V steels has been studied in order to show the effects of the alloying elements on the low-temperature fracture toughness. Bars of these steels were quenched and tempered to about 170 ksi yield strength (approx. 1170 MPa) and tested as precracked bend specimens.
