Abrasive Steel, Grit, Glass Bead, Aluminum Oxide Shot

Our cost-effective range removes ceramic residue from investment castings, deburring, and surface finishing of aluminum die castings. The steel shot that we offer is widely used in shots for blasting operations for inner/outer surface cleaning of steel castings, CI castings, s.g. Iron castings, forgings. According to the casting defects of gray cast iron According to the casting defects of gray cast iron cylinder body, type selection and coating formulation are developed For different casting defects (such as sand sticking, porosity, sintering, veining, shrinkage porosity at hot spot, etc.), the foundry should analyze the defect characteristics and causes together with the coating suppliers

Choosing the Right Blast Media for Abrasive Blasting

When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile. In the U.S., the depth profile is measured by mils thousandths of an inch.In the metric system, the micron(one millionth of a meter) is used. Ductile Iron Hardening Treatment - Iron foundryDuctile Iron Hardening Treatment :Hardening treatment to ductile iron could increase the surface hardness of castings, to make the casting with good hardness and abrasive resistance.. The normal quenching and tempering treatment could increase the surface hardness to about HRC 30 to HRC 40 of Rockwell Hardness, this process includes the heat heated to 880-930 centigrade, then quenching in Lodge HMSB 12 oz.

Reasonable machining hardness range for iron and steel

However, by the special steel alloy cutters or ceramic cutters, the cast iron with hardness under HB 300 can be machined. 2. The reasonable hardness range to cast steel Since the cast steel is more brittle than cast iron, so it can be machined more easily. The cast steel with hardness under HB 330 can be machined by the normal steel alloy cutters. Sand casting, vacuum casting and cast iron - Piano World Apr 06, 2012 · Cast iron is an iron-carbon-silicon alloy. Steel is similar, but with a lower carbon content (<2.1%). The iron atoms in cast iron have a certain order to them. At ambient temperatures, this structure is known as body centered cubic (BCC). At higher temperatures, the structure changes to face-centered cubic (FCC).

Sand castings are made by creating a negative in a bed of sand to create the cavity for casting. A sand shell creates a rough exterior to castings. Typical surface finish of sand castings are 250 Ra as cast, and need extensive work afterwards to create a surface finish that is acceptable in most applications.
