Q:Does the bending of stainless steel bars need heating?
Fine can fix with bending machine, but the comparative costs of SAF-t and bottom die. The rough can be heated, but it will change the strength of the workpiece.
Q:A stainless steel pull rod problem
Simply speaking, because the 200 series of prices cheaper than the 300 series, the appearance is not much difference, although the performance is far inferior to the application, but a short period of time there will be a growth trend, especially in the domestic inland areas, the lack of real understanding of stainless steel, manganese steel will have a great market. However, due to manganese steel containing manganese is very high, used in food utensils, long-term will be harmful to the human body, and manganese in the same nickel binding is not easy to be separated, for the use of renewable resources is very unfavorable, so the manganese steel is not environmentally friendly, long term to be eliminated.
Q:304 stainless steel bar, why not a good car?
Cutting force is large, the demand for cutting temperature is relatively high. Henan Zhengzhou stainless steel is the strength of the larger data, in the cutting because of its large tangential stress, plastic deformation, so in the cutting needs of the cutting force is relatively large. In the process of cutting stainless steel, stainless steel is a material which is very slow in thermal conductivity, so it needs cutting at high temperature. High temperature cutting usually gathered in adjacent cutting edge area, so that the tool wear is very serious.
Q:Is there any difference between 303CU stainless steel bars and 303F stainless steel bars?
The chemical composition of steel production standards (chemical composition of steel strip compliance requirements of not less than 10 of nickel, not less than 2 mo, not less than 16 chromium, carbon is less than or equal to 0.08), if there are people return or claim, all losses themselves.
Q:Stainless steel grounding rod, really can rust?
In practical application, the steel which is often corroded by weak corrosive medium is called stainless steel, and the steel which is resistant to chemical medium is called acid resisting steel. Because of the difference in chemical composition between the two, the former is not necessarily resistant to chemical medium corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. The basic alloying elements of stainless steel, as well as nickel, molybdenum, titanium, niobium, copper, nitrogen and so on, to meet the various requirements for the use of stainless steel structure and performance. Stainless steel is easy to chloride corrosion, because chromium nickel chloride is collocated elements, elements will be collocated to form stainless steel corrosion exchange assimilation.
Q:Round stainless steel bar is formed after how to deal with customers?
Hello, stainless steel round surface is bright, is the hot rolled stainless steel rod after cold drawing of cold rolling mill, the surface layer of the black color to remove.
Q:How many kinds of stainless steel bars?
According to the material quality, there are 4 kinds of austenitic stainless steel bars, ferritic stainless steel bars, martensitic stainless steel bars and duplex stainless steel bars
Q:Which items need 316 stainless steel to make?
The use of a wide range of pulp and paper equipment, heat exchangers, dyeing equipment, film washing equipment, pipelines, coastal areas, building materials for external use.
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:304 why are stainless steel bars hard and soft?
304 is austenitic steel, with work hardening, that is, after cold processing, such as wire drawing, cold heading, it will harden. If the processing is excellent 304, want to soften it again, very simple, annealing will do.
