Classification, type and chemical composition of stainless steel

Stainless steel is divided into martensite and austenite, ferrite and duplex. 1. Martensitic chromium stainless steel is mainly low-carbon or high-carbon steel with chromium content in the range of 11.5%-18%. Designations 403, 410, 414, 416, 416 (Se), 420, 431, 440A, 440B and 440C, the corrosion resistance of these steels comes from “chromium”. The martensitic stainless…

Classification and characteristics of aluminum alloy materials and application fields

Aluminum alloy materials are the most widely used non-ferrous metal structural parts in the industrial field, and are widely used in aviation, aerospace, automotive, machinery manufacturing, shipping, electronic machining, molds and chemical industries. Aluminum alloy materials are divided into different grades. Each grade material contains slightly different elements. Different grades are suitable for different ranges:…

Selection of “Copper Clad Steel” Copper Plating Process

The particularity of the wire processing industry makes the requirements of the copper plating process different from the conventional copper plating of steel parts. Therefore, how to choose a copper plating process suitable for wire processing is a very important subject. Generally, the basis for selecting the plating process is first of all the requirements…
