Heat resistant castings

 

         Heat resistant castings are capable of sustained operation while exposed to temperatures often exceeding 1200°F and up to 2100°F.  Demonstrating excellent resistance to warping, cracking and thermal fatigue heat resistant castings have many applications.

        Heat resistant castings are made of alloys that are typically divided into two catagories: Iron-Chromium alloys with 10% to 30% Chromium and lesser amounts of molybdenum and nickel. The HA and HC alloys are in this category and have a ferritic microstructure.

        The second category is the Iron-Chromium-Nickel alloys containing more than 13%Cr and more than 7% Ni. This category contains both ferrite-austenite and straight austenite microstructures. This category of alloys is typically chosen for higher temperature applications with corrosive environments. Alloys in this category can be used at temperatures up to 2100°F and withstand carburizing, oxidizing, and reducing atmospheres.  Alloys in this category include: HE alloy, HH alloy, HK alloy, HL alloy, HP alloy, HU alloy, HW alloy and HX alloy.

        Commercial applications for heat resistant castings include heat treat furnaces, cement kiln equipment, oil refinery heaters and furnaces, chemical process equipment, paper plant equipment, steel mill equipment, glass and rubber manufacturing equipment, paper processing equipment, and power generating equipment.

Melco makes make Blow Bars for the following crushers in High Chrome Irons, Manganese steel and also Martensitic Steel.

We have an in house Design Shop and make patterns for these in house. We can develop any kind of Blow bars based on the customer’s drawings. We will also help you decide the best material for blowbar based on the material you crush.

Manganese Steel wear parts

Melco Manganese wear parts are a relatively low-cost option, offering good wear life and are ideally suited for high impact applications where tramp metal or uncrushable objects are included in the feed material.

Martensitic Steel wear parts

Melco Martensitic wear parts are considered ideal in applications where the feed material varies. Offering impact resistance similar to Manganese Steel with improved wear properties, they also demonstrate good resistance to abrasive gouging.

Chrome White Iron wear parts/ High Chromium Spares

Melco Chrome White Iron wear parts are ideally suited to applications with high abrasion offering cost effective wear life.  They are not suited to applications where tramp metal or uncrushable objects are included in the feed material.
