it is 2 ~ 3mm, and in places with deep groove, it is 5 ~ 6mm. The distance from the nozzle to the working is generally no more than 5mm.
Steel strip, thin strip, roll strip, calendering strip and other strips can be cut with a thickness of 0.03 to 0mm (Note: stainless steel calendering strips of various thickness and width can be produced according to the needs of customers)
.The specific steps of continuous casting billet process of stainless steel pipe fittings are as follows: according to different steel grades, the vibration process of mold is matched with protective slag, which can improve the yield of 10%, save energy and shorten the production cycle,Price of 304 stainless steel strip, so as to improve the yield of molten steel.
The specification and appearance quality shall comply with the provisions of gb14975-2002 stainless steel seamless steel pipe. The steel pipe is usually 5 ~ 10m long (indefinite length) hot rolled steel pipe, and the hot-rolled steel pipe is equal to or greater than 1m. The wall thickness of cold drawn (rolled) steel pipe is 0.5 ~ 0mm, 0 ~ 7m; the wall thickness is greater than 0mm, 5 ~ 8m.
.Cold rolled oriented silicon steel strip (sheet) represents: 100 times of DQ + iron loss value (at the frequency of 50Hz, the waveform is sinusoidal, G is added after the iron loss value to represent high magnetic induction. For example, dq133 represents cold rolled oriented silicon steel strip (sheet) with iron loss value of 3 and thickness of 0.3mm. Now the new model is 30q133.
6 Density 400 & rdquo; Density of series: 93310s, 309S and 316316 density stainless steel coils of 30323042001 are divided into Austenitic, ferrite, martensite, duplex (ferrite austenite) stainless steel cold rolled coil and stainless steel hot rolled coil.
Today, Xiaobian can help you. If you want to choose high-quality stainless steel pipe water supply pipe, you can choose this: choose the material of stainless steel pipe water supply pipe.
Someone asked whether the stainless steel pipe was rusted and caused toxic problems?
Stress corrosion cracking (SCC) refers to the cracking caused by the combined action of stress corrosion stress (mainly tensile stress) and corrosion of austenitic stainless steel Austenitic stainless steel is prone to stress corrosion in corrosive media containing chloride ions. When the Ni content reaches 8% - 10%, it is a long-term enterprise engaged in stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe. Welcome to consult. The stress corrosion tendency of austenitic stainless steel is very large. Continue to increase the Ni content to 45 ~ 50%, and the stress corrosion tendency gradually decreases until it disappears.
The atoms around the gap rearrange with time, resulting in the continuous accumulation of holes, weakening the material, and finally forming macro cracks,S30815 stainless steel plate, resulting in the fracture of stainless steel pipe material. Compared with room temperature, high temperature promotes the accelerated oxidation of materials and the accelerated diffusion of atoms. Under the action of stress, which reflects the relationship between deformation and time under specific temperature and stress structure. The typical creep curve includes three stages: creep stage, with a gradually slowing creep rate; The second stage of creep: steady-state creep stage, which is an important stage when the stress process and recovery process reach equilibrium; In the third stage of creep, the creep process accelerates until fracture.
Latest consultation.When the stress exceeds the limit, even if the stress no longer increases, the steel or sample continues to have obvious plastic deformation. This phenomenon is called yield. Professional stainless steel plate, stainless steel coil, then the yield point & sigma; s = PS / fo (MPA) service and quality. Your satisfaction is our pursuit! Welcome to inquire The small stress value when yielding phenomenon occurs is the yield point. Let PS be the external force at the yield point s and fo be the cross-sectional area of the sample, MPa is called MPa, which is equal to n (Newton) / mm (MPA = 106pa, PA: Pascal = n / m.
In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness of various stainless steel coils meet the requirements, the stainless steel coils must undergo heat treatment such as annealing solution treatment and aging treatment before delivery. The corrosion resistance of stainless steel coil mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the interior of stainless steel coil
(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,Stainless steel round pipe 304, 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
L is a model of stainless steel pipe, and its current use value and market demand are also very large. People who often pay attention to the price of stainless steel pipes will find that the price of stainless steel pipes fluctuates greatly, sometimes rising to an exaggerated degree, and sometimes falling to the bottom. Only after understanding the factors affecting the price of stainless steel pipe can we be keenly aware of the fluctuation of stainless steel pipe price and respond in advance. So what is the price of L steel pipe?
Welcome to inquire.National standard thickness of stainless steel pipe. Stainless steel pipe is a brand of stainless steel produced according to American ASTM standards. Before the national standard thickness of stainless steel pipe, there are stainless steel pipe national standard thickness national standard wall thickness table product name specification material price (yuan ton) rise and fall welded pipe 6 points 5mm (& phi; 275mm) 3850 + 30 welded pipe 1 inch 0mm (& phi; 330mm)
Therefore, there are requirements for the service environment of stainless steel, and it is necessary to remove dust frequently and keep it clean and dry.
The shielding gas is argon with a purity of 999%. When the welding current is 50 ~ 50a, the argon flow is 8 ~ 0lmin, and when the current is 50 ~ 250A, the argon flow is 2 ~ 5lmin.
.201 series & mdash; Chromium nickel manganese austenitic stainless steel.
The steel grades for JIS mechanical structures are: S + carbon content + letter code (CK), in which the carbon content is represented by the intermediate value & times; 100, and K: represents steel for carburizing. For example, the carbon content of carbon coil s20c is 0.18-0.23%. The grades of silicon steel sheets in China and Japan are.
The process of this product determines its limited performance. Generally, the precision of seamless steel pipe is low: uneven wall thickness, low brightness on the inner and outer surface of the pipe, high sizing cost, and there are pockmarks and black spots on the inner and outer surface, which are not easy to remove; its detection and shaping must be processed offline. Therefore it embodies its advantages in high pressure, high strength and mechanical structure materials.
