21. This leads to an increase in the yield strength of the material and a subsequent decrease in ductility. 22. It has yield strength of and ultimate strength of for medium weight rolled shapes and plates from thick. 23. Designers can overcome these issues by choosing materials with higher yield strengths , however usually at higher costs. 24. Aluminized steel was developed for providing more structural durability and a high yield strength in highly corrosive environments. 25. The process of liquefaction implies a considerable to almost complete loss of yield strength of the layer involved. 26. The'HY'steels are a series of steels with high yield strength , hence the name. 27. This necessitated an additional leak-proof Mo ) of bars with yield strength of 850 N per mm2. 28. Elements such as copper or tin may be added to increase tensile and yield strength while simultaneously reducing ductility. 29. Burnishing may occur on any sliding surface if the contact stress locally exceeds the yield strength of the material. 30. However, this increases the thread's yield strength , surface finish, hardness, and wear resistance.
