Product Description

Details Concentrate or Not: Non-concentrate Shape: lump or powder Alloy or Not: Is Alloy Dimensions: 10 to 130mm HS Code: 7202801000 Model Number: FeW80-A, FeW80-B, FeW80-C, FeW70 Chemical Composition: Fe, W, C, P, S, Si, MN, Cu, As, Bi... Packaging Detail: 100kg per iron bucket Specifications: 1. Properties: Wolfram is one of the important alloy elements which are used to make special steel. While Wolfram reduce a little elongation rate of steel, it raises strength limit and yield point and also raises hardness and abrasion resistance of steel. It is very important that tungsten has good influence on high temperature mechanical properties of steel to improve heat resistance and tempering stability of steel. 2.
