Q:What are the BITAUTO stainless steel bar?
The carbon content in the stainless steel bar is also a key indicator of the hardness of stainless steel. The harder the carbon content is, the harder the material will be, and the opposite is the opposite.
Q:What is the hardness of 416 stainless steel bars after heat treatment?
Such stainless steel is also chromium as the main alloy elements (chromium, 10~18%), carbon in the range of 0.08~1.2%, the majority do not contain nickel, and a small amount of nickel (2.5%). Martensitic stainless steel heat treatment generally has the following processes:1, after annealing - hot rolling, because of the rapid cooling and hardening, in order to soften treatment, increase ductility, need to be annealed. The annealing temperature is 850~9200C, the furnace is cold to 6000C, then the air cooling is called full annealing, and is usually carried out in bell type furnace. The annealing temperature is 620~7800C, and then air cooling is called process annealing, which is usually carried out in a continuous furnace.2, quenching martensitic stainless steel can obtain very high hardness after high temperature quenching, its quenching temperature is 925~10650C, oil quenching or air cooling. In order to eliminate the internal stresses after quenching, general stress relief, annealing and tempering are also necessary. However, such treatment is generally used for bars and mechanical parts, and steel strips and steel plates are seldom used for such treatment.
Q:What about the weight of stainless steel bars?
The density of stainless steel with 8.0kg*10 three times /m fandThe mass of a steel bar is equal to the volume by the density;The volume of a steel bar is equal to the square of the outer diameter by the PI divided by four.
Q:The difference between 440C stainless steel bars and 420 stainless steel bars
440C is a high strength cutting tool steel, carbon is slightly higher. 420 stainless steel applies to all kinds of precision machinery, bearings, equipment, etc..
Q:How much temperature would you like to burn the stainless steel bar red?
The metal will has 680 degrees, 960 degrees of dark redOrange 1100 colors, when the temperature exceeds 1300 degrees, will appear incandescent.
Q:How many kinds of stainless steel bars?
According to the material forming process, there are 2 kinds of forged stainless steel bars and hot rolled stainless steel bars
Q:Which is good, the moxibustion bar, the stainless steel and the brass?
Moxibustion stick, also called warm moxibustion moxibustion tube or rod is a cylinder made of metal materials such as the tool, the cylinder bottom pointed flat sleeve, a small tube, a small tube around the hole. Materials are pure copper, stainless steel, iron and so on.
Q:What steelmaking furnace for stainless steel bars?
At present, most with two kinds of stainless steel smelting furnace, a furnace is another electroslag furnace, intermediate frequency furnace is mainly used for less demanding occasions do not yield, while electroslag furnace materials used in the occasions with higher requirements.
Q:What are the manufacturing processes of stainless steel bars?
According to the weight of the product selects the corresponding ingot and hot rolling, straightening, cutting head, rod inspection and packaging Sinotrans
Q:How about 440C stainless steel?
4116, I do not know, stainless steel, I heard that it is not good grinding (high wear resistance), the price may be higher440C stainless steel is quite good, but also relatively inexpensive, sanding will not be too difficult, hardness, toughness, rust resistance are good. All together, I like 440C, but I don't expect it to be too high
