S-TEN™1

<Features>
 There are cases where the exhaust gas treatment equipment of waste combustion facilities
 or boiler air preheaters using fuel containing sulfur and chlorine is subjected to sulfuric
 and hydrochloric acid dew-point corrosion. In such an acid dew-point corrosion environment,
 not only common seel but also stainless steel cannnot be used.S-TEN 1 has higher corrosion
 resisitance in such environments 

<Equivalent steel grade, chemical compositions>

• ASTM A423 Gr. 3, ASME Code Case 2494
• 0.3Cu-0.1Sb
