RollWell

Rollwell consumables are available in open are (OA) and submerged arc (SA) process. Submerged arc wires are designed to work with specific type of fluxes. Fluxes are available in drum pack or in bags with controlled grain sizes.

Rollwell Range of Consumables :

A range of properties can be obtained, depending upon the composition of the weld deposit and the subsequent heat treatment procedure. Compositions are restricted by metallurgical factors affecting both hot and cold cracking. Weld process can be selected depending on roll material, deposition rate and cost of product.

Some of features of Rollwell products are as under

• Elevated temperature oxidation resistance.Resistance to localized pitting and crevice corrosion.
• Maximum resistance to stress corrosion
• Maximum tempering resistance to prevent softening during service.
• Resistance to thermal and thermo mechanical fatigue.
• High thermal conductivity.
• Low coefficient of thermal expansion.
• High hardness and resistance to abrasive and adhesive wear
• High strength and toughness, good weldability, reasonably priced.
