SUGAR REFINING.

The following base metals can be hardfaced: • Stainless steels • Manganese steels • Carbon and alloy steels • Cast irons • Nickel-base alloys • Copper-base alloys Carbon and low-alloy steels are strongly magnetic and can easily be distinguished from austenitic manganese steel which is non-magnetic. Carbon and low-alloy steels with carbon contents of Product Purity Six Ways to Attack Metal Contamination to Improve Product Purity and Avoid Recalls The responsibility for product purity is shared by processing plants and their suppliers. • Metal carbide and soft austenitic matrix - These alloys contain large amounts of metal carbides in softer matrix and are good for severe abrasion applications. If the hardfacing alloy produces check cracks, such as a chromium carbide alloy, then it's wise to use a tough manganese product as the buffer to blunt and stop the check cracks from penetrating into the base metal.
