We strictly in accordance with the national standard "GB / T18838.3-2008 high carbon steel shot and grit", "SFSA20-66 steel abrasive standards," American Society of Automotive Engineers Association of American steel "SAE J1993 standard sand casting", People's Republic of China ferrous metallurgy industry "YB / T5150-1993 standard sand casting," the US military standard "MIL-S-851C clean up and strengthen with metal grit and steel shot," and the International Organization for Standardization "ISO11124-3 high carbon cast steel shot Grit standard "to produce. ? Grit Main Specifications:? Name (grit) sand casting chemical composition of carbon (C) 0.70 ~ 1.20% manganese (Mn) 0.35 ~ 1.20% of silicon (Si) 0.40 ~ 1.20% sulfur (S) ≤0.05% phosphorus (P) ≤0.05% average hardness (measured at 500g load) GP grit: 42 ~ 50HRC (399 ~ 509HV) GL grit:? 56 ~ 60HRC (620 ~ 713HV) GH grit:? 63 ~ 66HRC (759? ~ 889HV) Hardness deviation range of the maximum deviation of ± 3.0HRC or ± 40HV uniform microstructure of tempered martensite or tempered troostite + dispersed carbide minimum density (alcohol displacement assay) 7.4g / cm3 Shot , Grit range of applications: 1. Cleaning: shot blasting, shot blasting, casting cleaning, blast cleaning castings, forgings, shot blasting, shot blasting casting sand forgings, steel cleaning, cleaning up steel, steel cleaning, H-beam cleaning, steel cleaning. 2, rust: shot blasting, abrasive blasting, rust casting, forgings rust, rust steel forgings descaling rust steel, H-shaped steel rust, steel rust, sand-blasting , steel blasting, sandblasting the secondary sand-blasting, sandblasting the secondary blast cleaning. ? 3, strengthen: shot peening, heat treatment pieces of shot peening, shot peening gear. ? 4, Shot: steel shot, steel sandblasting, ship blasting, steel shot, steel shot. ? 5, Shot: steel blasting, steel shot blasting, steel shot blasting. ? 6, playing sand: play sand. ? 7, pretreatment: treatment before painting, coating pretreatment, surface preparation, pretreatment Ship, steel pretreatment, pretreatment of steel, steel pretreatment, before the steel handle. Different hardness Grit 1, GP Grit: made of this new abrasive, sharp edges are shaped, the course will soon be rounded corners, particularly suitable for descaling steel surface pretreatment operations. 2, GL Grit: Although such grit emery hardness is higher than the GP, but still lost in the sandblasting process corners, particularly suitable for descaling steel surface pretreatment operations. ? 3, GH grit: high hardness such grit in blasting operations will remain the edges of the formation of the rules, hairy surface is particularly effective. GH grit blasting machine for the job, should be considered in preference to the price factor construction requirements of the occasion (such as cold rolling mill roll processing). This grit blasting equipment is mainly used for compressed air. ? Gangsha For:? ???
