Is there any problems with using a CR13(410ss with 13% cromium) valve trim in 30% or more H2s (wet or dry) instead of 316 ss. CR13 trim is usually used by all valve maufacturers as a standard trim in a standard valve. Most A105 & A216 bodies meet nace requirments of R22 or less but the trim is usually different in nace certified valves, most nace trims are 316ss.
