Overview

Why This Route Exists

High alloy parts are where material choice, not machine time, decides the cost and the service life. Eurona groups this business into four families: stainless steel food machinery parts, incineration grate bars, screw pump rotors and biomass furnace castings.

The common thread is a hostile working environment — heat, abrasion, corrosion and high hardness — so casting, heat treatment, machining and inspection are planned as one route rather than as separate purchases.

Capability

Process And Quality Capability

Inspection

Dimensions, flatness, assembly clearance, 3D scanning, RT, PT, hardness, chemical composition and tensile testing.

Material Control

Chemical analysis on each melt, sampling from the product body and third party testing for special elements.

Heat Treatment

Rotors are annealed to 20-35 HRC before machining, then quenched at about 1020 °C to 59-63 HRC.

Problems It Solves

What Usually Goes Wrong Without This Route

Grate bars burn out or deform early because the alloy was substituted for a cheaper grade.
Stainless parts for food contact arrive without material certificates or with the wrong grade.
Rotor hardness is quoted but never measured, so wear life varies from batch to batch.

Choosing Heat Resistant Alloys for Grate Bars and Furnace Castings

Grate bars are consumables, so the alloy decides the operating budget. This guide explains the grades Eurona works with and how the working condition narrows the choice.

Buying Guide

What NDT and Quality Documents to Specify on a Casting Order

Most acceptance disputes come from an inspection scope that was never agreed. This guide covers what to specify and when to specify it.
