Jinan Huafu Forging Co., Ltd is located in Zhangqiu City, Shandong Province, 45 kilometers to the Jinan Downtown, next to the 309 national way, information collected fast, traffic convenient. Our company covers the 8, 000 square meters area, over 100 employees, annual output is 15, 000 metric tons. Our main products are forged, cast steel balls, steel cylpeb, decorative iron wrought products. The application for our products are mines, cement plant, building material, power station industry. Our products both sold to the domestic and foreign country. The products export to America, Chile, South Africa, Australia, Korea, Japan and other countries and regions, got highly appreciated by our customers.
Our company regulate and produce strictly according to the ISO9001 Quality Standard. The main products are:
1. Anti resistant steel ball: Dia. 20mm-dia. 150mm forged steel ball and high, medium, low chrome cast ball in dia. 17mm-dia. 120mm. Huafu steel ball is good in accurate dimension, roundness geometry shape high hardness and good mechanical properties with good characteristic of anti resistant, no deformation, no break. Huafu steel ball is uniform surface hardness, hardness distribution uniform for the advance quenching device in the producing process.
Huafu steel ball have the below characteristic: A: High hardness( surface hardness is50-65 HRC, volume hardness is 48-58 HRC with uniform hardness distribution); B: High impact toughness( above 12J/cm2); C: Low break rate( anti break is ten times compared to the normal cast and forged steel balls, factual break rate is lower than 1% when falling times is above 20, 000 from the 10 m high dropping machine) D: No deformation: Steel ball no deformation out of the round for using. Huafu steel ball is made from the perfect carbon steel and alloy steel.
2. Steel cylpeb: We absorb the advance technology, add the Cr, Mn, Si, Mg, Al, Cu and others to make the alloy cements. The products produce in the intermediate frequency furnace and fall to the high, medium, low chrome category. Its characteristic is steady quality, high hardness, anti resistant, low break rate, various kinds
3. Decorative wrought iron products: We mainly produce the forged baluster, spears, the assembles and the arctic iron door, fence, guarding windows, room furniture, various kinds for above. Our products are famous in the world by it's highly view and use value.
