CA6NM：Everything you should konw
For the maker of machine parts, no metal material is best. According to the various characteristics and prices of metal to choose the most appropriate metal materials to manufacture the most cost-effective mechanical parts, is the ultimate goal of customers to choose materials. The following is a brief introduction to CA
Classification of stainless steel
The development of stainless steel Stainless steel appeared since the early 20th century. The development of the stainless steel speed very quickly. There are more than 300 brand has formed a series of categories of steel. And application range widening. Consumption soared to the 1990 s, the world’s stainless steel consumption is growing at […]
The role of alloying elements in CA6NM martensitic stainless steel 8
The role of alloying elements in CA6NM martensitic stainless steel tube Adding micro alloy elements Ti, Nb and V in martensitic stainless steel tube is usually expected to form a nitrogen compound with C and N. As a result increasing the strength of the steel. Ti is a stabilizing element. At the same time it is […]

The role of——Si in CA6NM martensitic stainless steel Si is a strong ferrite stabilizing element in martensitic stainless steel . It can suppress temper embrittlement and the decomposition of retained austenite during tempering. At high temperature or in a strong oxidizing medium adding a certain amount of Si to the surface to form a layer […]

The role of——Al in CA6NM martensitic stainless steel First of all as a deoxidizer we often add Al element into steel. At the same time Al is also a ferrite forming element. As a result its promoting effect on ferrite formation is about 2.5~3 times of that of Cr. Al element can form a dense […]
The role of alloying elements in CA6NM martensitic stainless steel 5
The role of——Mn in CA6NM martensitic stainless steel Mn is a kind of element that expands austenite phase zone in phase diagram. In steel, the stability of Mn to austenite is only below Ni, which can greatly improve hardenability of steel. Thus, in super martensitic stainless steel Mn can partially replace Ni. However, the corrosion […]

The role of alloying elements in CA6NM martensitic stainless steel——Cu Cu has a weaker effect on the formation of austenite. A small amount of Cu addition can not optimize the martensitic microstructure of martensite. In the corrosive medium, Cu can form an enrichment layer under the oxide layer of the steel, thereby preventing the […]
The role of alloying elements in CA6NM martensitic stainless steel 3
The role of alloying elements in CA6NM martensitic stainless steel CA6NM martensitic stainless steel alloying elements ——Mo Mo——the addition of alloying element Mo in martensitic stainless steels is beneficial to the strength. And also to toughness and corrosion resistance. Mo is a ferrite forming element. It can reduce the Ms temperature. The addition of Mo […]
The role of alloying elements in CA6NM martensitic stainless steel 2
The role of alloying elements in martensitic stainless steel 2. The role of Ni in martensitic stainless steel Ni—— the alloying element has no strengthening effect on the matrix of martensitic stainless steel CA6NM. According to the known Cr will promote the formation of ferrite. Therefore a proper amount of Ni (4~6, wt%) should be […]
The role of alloying elements in CA6NM martensitic stainless steel 1
The role of alloying elements in martensitic stainless steel CA6NM: Cr 1. The role of alloy element in martensitic stainless steel CA6NM: Cr Cr——one of major alloying elements in martensitic stainless steel CA6NM. It plays a decisive role in corrosion resistance. With Cr in the steell the corrosion resistance of stainless steel in the corrosive medium will increase accordingly. […]
