We are glad to propose 500 MT of stain less steel mill scale. Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products. At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel. The recovery ratio after melting in furnace for the most valuable alloy elements is: - Ni: 3.5 - 4.5% - Cr: 6-8% From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows: Waste code: 10 02 10 The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers. Chemical analysis of the material is available on request.

The Solid CBN Inserts are made of cubic boron nitride micro power under the process of super high temperature and high press. Solid of CBN Inserts are used for rough and finish machining. More SuperHard s solid CBN inserts for multiple machining requirements. Whatever your cutting application requires, solid CBN inserts provide the best in geometry, hardness and performance.
Name: Solid CBN inserts Brief Introduction: solid cbn inserts are used for rough and finish machining of hard steel ,cast iron and hard surface workpiece. type: RNMN,SNMN,TNGN,CNMN,RCMN,RCMX application: turning hard steel,cast iron Details Cubic boron nitride inserts (CBN Inserts) is a high-performance type of cutting tool material from a polycrystalline mass. CBN is a high hardness, high heat resistance crystal synthesized by boron and nitrogen under high temperature and high pressure. Applications of solid CBN inserts: Processing workpiece: rough and finish machining of the hard steel ,cast iron and hard surface workpiece. Processing materials: ferrous materials possessing hardness from approximately 45 HRC as well as gray cast iron, Cr-chilled cast iron and wear alloys on a cobalt, nickel or iron basis. Usages of PCBN inserts: 1.PCBN bladesare mainly using in processing of hardened steel whose hardness is of HRC50-60. such as: carbon tool steel, bearing steel, die steel, high-speed steel and so on.
