SECO/WARWICK Press Release. "Meadville, Pennsylvania–SECO/WARWICK<br />

Corp. has received an order for an advanced new furnace that will provide improved<br />

durability for stainless steel heat treating."This vacuum furnace will come with a<br />

15-bar gas quenching system. <strong>The</strong> Super Expanite process improves the hardness<br />

and corrosion resistance for stainless steel. It is not a coating, but rather a new<br />

treatment process. SECO/WARWICK officials said they expect to have the<br />

equipment in place by early summer of this year. April 10/2013<br />

About SECO/WARWICK CO. <strong>The</strong> Vacuum Team offers vacuum heat treating<br />

furnaces for hardening, tempering, annealing, solution heat treating, brazing,<br />

sintering, carburizing, carbonitriding, high vacuum, CVD–graphitizing and<br />

degassing. SECO/WARWICK has built some of the largest and technically advanced<br />

vacuum furnaces in operation today, developing advanced technologies like<br />

Universal HPQ (High Pressure Quench), PreNit® & FineCarb® LPC vacuum<br />

carburizing, fully automated control systems and modeling software. Vacuum<br />

furnace configurations are available for vertical, horizontal and elevator style<br />

furnaces. Both cylindrical and rectangular hot zones with metallic or graphite<br />

heating elements are available for both new and used equipment. Retech LLC<br />

provides vacuum melting equipment. Visit http://www.secowarwick.com/<br />

Gas vs.; Electricity. <strong>The</strong> decision as to whether to use natural gas as opposed to<br />

electricity to heat furnaces comes down to two issues, availability and pricing.<br />

Obviously if natural gas is not available there is no decision to be made which<br />

means generally the decision comes down to relative cost. Certainly in most areas<br />

of North America this is a "no brainer" natural gas is far cheaper than electricity and<br />

the long term forecast is that the spread will only widen. One of the charts below<br />

shows natural gas pricing over the years, the second electricity. We wouldn't have<br />

to debate a second about which energy source to use. And while we are looking at<br />

charts the furthest chart down shows nickel pricing and all we can say is all is quiet<br />

on the nickel front. April 9/2013<br />
