Materials of Construction - ZeCor™
September 29, 2004

Introduction

ZeCor™ is a high silicon containing stainless steel similar to other high silicon austenitic stainless steels such as SX and Saramet.   Corrosion data from laboratory studies and plants service confirm corrosion rates of less than 0.0254 mm/yr (1 mpy) in concentrated hot sulfuric acid.

ZeCor™ can be used for construction of all metal towers, piping, distributors, orifice plates, pump tanks, mesh pads, etc.

ZeCor™ is available exclusively from Enviro-Chem Systems.

Weldability

ZeCor™ can be welded using basic gas tungsten arc welding (GTAW-TIG) techniques using ZeCor™ filler wire. If done properly the resulting welds have the same corrosion resistance properties as the parent material.

Weldability is similar to that of 304/316 stainless steel.
