Case Parcitank wine tanks

Outokumpu

Challenge

Parcitank, for whom wine tanks are a key product, needed excellent corrosion resistance due to carbon dioxide released by wine fermentation.

Solution

Outokumpu’s Supra 316plus is a new high chromium austenitic stainless steel grade that represents a competitive alternative to 316(L) and provides better corrosion resistance and strength.

“Salud” to the Supra 316plus

Parcitank, one of Europe’s leading manufacturers of storage tanks, has been exploring Outokumpu’s Supra 316plus for making wine tanks.

As wine ferments, it produces carbon dioxide fumes that rise to the top. “That is why, generally, the upper part of the tank is made of 316 stainless steel, and the rest of the tank is made of 304,” explains Parcitank’s Director of Production, Antonio Parra.

Outokumpu’s Supra 316plus is a new high-chromium austenitic stainless steel grade that represents a competitive alternative to 316(L). “It has better resistance to corrosion compared to the standard 316 grade, and more strength,” says Parra.

 

Collecting information

Taking these advantages into account, Parcitank has decided to purchase Supra 316plus and is planning to use the new grade more widely. “We are performing tests in the lab, following the specifications from Outokumpu,” says Parra.

“Initially it is performing pretty well, so we are going to manufacture several wine tanks, for our own winery and for some trusted clients in our area,” announces Parra.

This change of material is important to Parcitank since wine tanks are one of their key products. The company is based in the winemaking region of La Mancha in central Spain, and makes wine tanks for customers worldwide.

Parcitank is closely monitoring those tanks to better understand the performance of the material. “After that, we will be able to use this material more broadly,” says Parra.

 

Looking forward to new grades

Parcitank’s quality control process will make it possible for the company to progressively expand the use of Supra 316plus. As a business that requires large amounts of steel for its operations, Parra highlights the need to keep up to date with the latest developments in the industry.

“That is important for us. We are always very interested in any new innovations and new grades, and we rely on steelmakers to inform us of new materials that are best suited for a particular product and sector.”

Recommended products and insight

Building and infrastructure

Landmark buildings and bridges make a statement. When they’re built of stainless steel, that statement reflects an enduring legacy – a legacy of timeless beauty, exceptional strength and unmatched durability.

Bridges and infrastructure

Bridge projects are in a class of their own – just like Outokumpu stainless steel. Marked by harsh environments, heavy lifetime usage and high aesthetic expectations, bridges demand special considerations upfront if they’re to go the distance.

Forta

The Forta range contains duplex and other high strength stainless steels that enable thinner structures and weight reduction (measured in Rp0.2 > 400 MPa. PRE 16 to 43).

Rebar

Outokumpu offers a full range of stainless-steel rebar with high availability.
