Polishing

Tool should be polished using the guidelines for polishing

stainless steel. When properly polished, an A-1 surface finish is

achievable. .

WeldingRecommendations THYROPLAST PH X SUPRA is recommended for tools/

molds for the processing of corrosive plastics.

Refer to aging diagram below for aging temperatures.

Aging is performed by uniformly heating to aging tempera-

ture, equalizing temperature from surface to center, holding

for 4 hours at specified temperature, and air cooling.

HardnessHR

THYROPLAST PH X SUPRA can be welded using shielded

metal arc welding process. Oxyacetylene welding is notrecommended.

THYROPLAST PH X SUPRA usually does not require

preheating to prevent cracking

AWS E/ER 630 filler material should be used to produce propertie

comparable to the parent material. If welded in the solution-treated condition, the welds can be aged

to the desired strength level after welding.

If welded in the over aged condition, the part must be solution

treated and then aged. It may be advantageous to preheat to ap-proximately 2000F and weld in the over aged (H 11500F) conditionfor repair welds more than 1 deep or where high welding stressesare anticipated.

For less critical applications, where high weld strength, hardness,

final polish or texture quality is not paramount a standard austenitistainless steel filler, E/ER308L, should be considered. This type o

filler will not produce the precipitation hardening response.
