Shanxi, Xinjiang harmony Machinery Co., Ltd. production of cast iron HT300 categories: gray cast iron material grades: HT300, referring to the test bar diameter: 30mm minimum tensile strength of 300MPa gray cast iron. Material Standard: GB 9439-88 gray cast iron: Malleable iron flake graphite: graphite ductile iron floc: spheroidal graphite cast iron vermicular: Graphite for wormlike Machinery Co., Ltd. Shanxi, Xinjiang harmony classification Share iron products: Press carbon in the presence of different HT300 cast iron status and form, can be cast into: white cast iron: the great majority of carbon in ferrite and peaceful state of existence Xinjiang mechanical fracture bright white, hard and brittle ferrite mechanism is seldom used. Carbon exists in the form of gray cast iron with graphite: graphite flake exist. Malleable Iron: floc. Ductile iron: spherical. Compacted graphite iron: wormlike in the organization of the same matrix, in which the mechanical properties of ductile iron (strength, ductility, toughness) is the highest, followed by HT300 malleable cast iron standards, compacted graphite iron production also followed HT300 cast iron, gray iron most poor. However, due to the low cost of gray cast iron and has a casting, workability, abrasion and shock absorption are excellent features, is the industry's most widely used cast iron. Xinjiang peaceful machinery, iron HT300 Yuncheng, Shanxi, Xinjiang and peaceful harmony by mechanical machinery Limited. Shanxi, Xinjiang harmony Machinery Co., Ltd. (www.xianghemc.com/) strong, credible, Shanxi Yuncheng machining industry has accumulated a large number of loyal customers.
