Standard Wire mesh of 40 SIZE having wire diameter of 0.011 " and Opening of 0.014". It can with stand how much pressure drop across mesh with out any back support of perforated plate or other.
The concern with an unsupported mesh screen for a Y-strainer or basket strainer would be the screen material collapsing under high differential pressures. This would be more of a problem as the screen becomes more clogged.
The company I deal with is called Mueller Steam Specialties, www.muellersteam.com. They have various different charts in their Support - Technical Center section, including pressure drop charts, Cv values and clogging curves.
