wire drawing and wire drawing
Surface treatment difference: surface treatment is usually divided into polishing, and the cost is about 1 yuan and 1 meter. If it is thrown into the lens barrel, the cost per ton will increase by 3000 yuan.
The folded stainless steel hot rolled strip is hot rolled into a strip with a thickness of 80mm-00mm and a width of 50mm-1200mm.
.Section shape stainless steel pipe can be divided into round pipe and special-shaped pipe according to the section shape. Special shaped tubes include rectangular tubes, rhombic tubes, elliptical tubes, hexagonal tubes, octagonal tubes and various cross-section asymmetric tubes. Special shaped pipe is widely used in various structural parts, tools and mechanical parts. Compared with circular pipe, special-shaped pipe generally has large moment of inertia and section modulus, and has large bending and torsion resistance, and the hot rolled steel strip has good ductility and toughness.
.In addition, when selecting the reasonable thickness of the steel plate, its service time, quality and stiffness should be considered, and the strength requirements of the plate under pressure should be considered; Thermal conductivity; Distribution of pressure and format specification of pressing plate.
As long as it is a socket connected stainless steel wire, buttress must be set through calculation.
Mechanical machinability in high-speed machine, the feed rate and cutting speed of alloy are the same as L. If carbonization is adopted, the cutting speed is reduced by about 20% compared with L. the performance of machinery and equipment and their components plays a key role here.
As we all know, stainless steel pipe has a strong ability of atmospheric oxidation and is not easy to rust under normal circumstances & ldquo; Stainless steel pipe & rdquo; Hence the name of. But what I want to tell you today is that stainless steel pipes will also rust. I believe many friends will be surprised! I believe there are many people who don't know how to explain to customers! Next, let's popularize science!
W = (outer diameter wall thickness) & times; wall thickness & times; 0.02491 = KGM (weight per meter).
Ti-5a alloy with improved titanium and overall corrosion resistance has been used to manufacture u and Pu solution evaporation boilers and heat recovery evaporation boilers in Donghai reprocessing plant, Japan. In addition, because zirconium has stable corrosion resistance in the environment, zirconium is used in its continuous dissolution tank in the reprocessing plant in liusuo village, Aomori County, Japan. The US Academy's ruling that the countervailing duty is not suitable for products from non market economy countries has just given China's steel pipe enterprises a little relief. The anti-dumping stick from the EU has given a heavy blow to hundreds of domestic stainless steel pipe manufacturers.
Service first.Relevant information stainless steel export is an important part of China's export economy. It plays an important role in stimulating China's economic growth. However, from the current situation of China's stainless steel foreign trade, China's stainless steel export has encountered great resistance.
L stainless steel pipe is a kind of hollow long round steel, which is mainly used for industrial transmission pipelines and mechanical structural components such as petroleum, chemical industry medical treatment, food, light industry, etc. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in all kinds of manufacturing mechanical parts and engineering structures.
Stainless steel belt, stainless steel conveyor belt, stainless steel belt, stainless steel coil belt, ultra-thin stainless steel belt.
2020303043310s, 331632404420, 430 and other materials.
Product line.2D cold rolled, heat treated, pickled or similar matt surface.
In many construction sites, we use this kind of welding for priming, which can effectively ensure its quality and has certain construction difficulties. Therefore, careful and skilled welders should be selected for this work.
It has good local corrosion resistance. Compared with austenitic stainless steel with the same alloy content, its wear-resistant corrosion and fatigue corrosion properties are better than austenitic stainless steel.
.All decreased in varying degrees, the prices of construction wire rod and rebar, which account for a large proportion of China's steel output, fell by 9% and 7% respectively, and the prices of medium and heavy plate and hot rolled coil fell by 7% and 7% respectively.
(II) The price of steel has been running at a low level. From January 31 to June 2012, the overall performance of the domestic steel market was depressed. With the substantial release of crude steel production capacity, the market supply and demand fell into an imbalance and the steel price entered a downward channel, which has been weak for more than four months. As of June 26, 2013, the steel price index had dropped to 100.48 points, lower than the first 6 points. The prices of eight steel varieties mainly counted by the iron and steel industry association were lower than the first 6 points
Cold rolled steel strip shall be delivered in the state of heat treatment (annealing, normalizing and tempering after normalizing), and shall be delivered smoothly.
