Expanite surface hardening process for stainless steel pumps

The Expanite surface treatment is a GAME-CHANGER in the industry. Parts can be treated with extremely short leadtimes – a few days which is previously unseen within surface hardening of stainless steel.

Stainless steel is the material of choice if corrosion properties are of importance – so for the food & beverage industry. In many cases, however, the surface of stainless steels is prone to excessive wear. This is a big issue especially in pumps that are used in food handling where abrasive and corrosive media are handled.  Expanite just achieved a major break-through in the pump industry with German, US and Japanese customers by increasing the surface hardness of both, screw and PD pump parts that are used in food industry

With Expanite, it’s possible to increase the surface hardness of stainless steels by up to 10 times, while maintaining or even enhancing corrosion resistance. This method is considered unique since it’s suitable for austenitic-, ferritic-, martensitic and duplex stainless steels. The Expanite process improve resistance against surface wear such as galling, cavitation erosion and abrasive wear. 

With the Expanite treatment we reduce substantially the risk of corrosion of the materials and improve the cleanability. Also the mechanical and wear properties are remarkable Increased without adversely affecting corrosion resistance a huge benefits for many industries due to decrease downtime and thereby achieve cost savings.

After Expanite treatment surface is suitable for direct food contact - FDA conform process.

Benefits include:

  • Increased surface hardness to 1000-1500 HV0.05 (depending on base material and surface conditions)
  • Non-galling and wear resistant demands of industrial fluid handling pumps
  • No risk of delamination and spalling
  • Lead-time down to 3working days
  • Reliable and repeatable solution - materials remain unchanged after treatment

Surface hardening.

The technology of Expanite can increase the value of the products of many industries significantly - from knives, valves via mixers and grinders for the food industry, to pump, extruder screw and injection parts for the automotive sector, as well as screws, bolts and washers in the different industries apply. There are 3 different basic processes, which each can be optimized according to customers' requirements in terms of abrasion, wear, corrosion and scratch resistance. This means that Expanite develop and customize solutions for many different companies and industries.
