In order to improve the strength and hardness of iron, a small amount of carbon is often added to pure iron. Due to the interaction of iron and carbon, the foll

The process of steel heating is a thermal activation process. The austenite transformation of carbon steel includes four processes: austenite nucleation, carbid

There are many classification methods for wrought aluminum alloys. At present, most countries in the world usually classify them according to the following thre

Precipitation hardening stainless steel is a material with higher strength at room temperature and below 500°C. 05Cr17Ni4Cu4Nb (630) is a low-C martensite m

At present, the widely used biomedical metal materials mainly include stainless steel, cobalt based alloy, titanium and titanium alloy (including titanium based

The carbon tool steels used as cold stamping dies mainly include: T7A, T10A, and T11A, among which T10A steel is the most commonly used.

Classification, use and grades of alloy steel

Alloy steel is a special purpose steel by adding a certain amount of alloying elements to Fe-C alloy steel. The c

2Cr13 steel should belong to stainless steel from the classification point of view. A more accurate classification should be attributed to martensitic stainless
